  • Review of the Tamron 18-400mm F/3.5-6.3 DI-II VC HLD Zoom Lens

    Tamron has been specializing in super-zoom lenses for the last few years. You may be familiar with their 16-300mm, 18-270mm or 150-600mm lenses. Their newest super-zoom is an even more astonishing focal length, the Tamron 18-400mm. I recently had a chance to review this lens for a few weeks so I thought I’d give you an idea of who this lens is for, the good, the not-so-good, and my overall recommendation.

    Review of Tamron 18-400mm F/3.5-6.3 DI-II VC HLD Zoom Lens - Hibiscus

    About this review

    I know you already know this (because you read ALL my pieces for dPS, right? Right?!) but my lens reviews are pretty real world. I don’t sit in a lab or use techy gizmos to measure sharpness. I actually hold a lens in my hands and shoot with it. This lens was tucked in my favorite bag for most of August.

    That said, my intention was to see how a lens holds up for an actual shoot. I used this lens to photograph Lipizzan horses at a dressage performance as well as at the racetrack. Then I used it on a mission to photograph old barns and finally to make some macro flower images.

    The goal was to make images at most focal lengths with a variety of apertures, but a few might have been skipped because I was really out there shooting. I shoot at the focal length, shutter speed, ISO and aperture that each situation calls for. So let’s just say I apologize in advance if I’ve skipped something important to you. Give me a shout in the comments if that’s the case. I’ll dig through my notes and image archives to see if I can answer your question.

    Lens specs

    Let’s start off with a quick overview of the lens specs. This lens is for Nikon and Canon APS-C (crop sensor) cameras only. I tested the lens on a Canon 7D Mark II.

    The Tamron 18-400mm super-zoom is a variable aperture lens. Meaning that at 18mm, the maximum aperture (largest opening) is f/3.5. But when you zoom into 400mm, the maximum aperture is f/6.3. The minimum aperture (smallest opening) is f/22 at all focal lengths.

    The lens has an HLD Autofocus Motor that is quick and quiet for a consumer lens at this price. It also has Tamron’s standard VC Image Stabilization. This feature enables you to get sharper shots while hand-holding at longer focal lengths. The lens also has what Tamron calls Moisture-Resistant Construction. I’m relieved to tell you I didn’t get to test this feature.

    The minimum focusing distance – important especially if you want to try your hand at making macro images – is 17.72″ (45 cm). Macro is usually a 1:1 ratio and this lens only produces 1:2.9, but I was pleasantly surprised with my macro results.

    If you use screw on filters, like a circular polarizer, the front thread is 72mm. The lens is 1.56 pounds (710 g) and approximately 3.11” in diameter by 4.88″ in length (79 x 123.9 mm). It’s an incredibly compact lens for this focal length range.

    The price, at the time of publication of this article, is $ 649.00 USD.

    Who is this lens for?

    I would describe the ideal user of this lens as an amateur or enthusiast. If you’re an amateur photographer who travels but doesn’t want to carry more than one or two lenses, this is the perfect choice for you.

    With an 18-400mm focal length, you might not need to ever change the lens, except in a dark indoor situation, when you need either flash or perhaps the fast f/1.8 maximum aperture of a nifty fifty.

    This lens would also be great for a busy parent who needs more than a smart phone to capture pictures of soccer matches and dance recitals but who doesn’t have a ton of extra room in her carryall bag. The compact size and weight of the Tamron 18-400mm make it an easy addition to any parent’s standard kit.

    What’s good about this lens

    The size of this lens just can’t be beat. At only a pound and a half and less than 5 inches long, it’s a lot of focal length in a very small package. I was really taken with how small it was since I normally shoot with such large neck-and-shoulder-busting glass.

    Hand-holding this lens for an afternoon at the race track wasn’t even remotely painful. With the insane focal length capabilities, I didn’t even bother to carry a second lens with me (or even my camera bag!) and that made for a really care-free afternoon.

    Great for landscape images

    It’s also a pleasure to catch a pretty landscape out of the corner of your eye and to simply zoom out to 18mm to capture it. Typically if you’re shooting with a long lens, you have to take the time to switch over to your wide-angle lens, take the shot and then switch back to your longer focal length lens again. Well, actually, if you’re me, you see that landscape and think ooh, pretty and then walk away without taking the shot.

    I’m lazy that way so this was the first time I’ve actually made images of the racetrack itself. The lens performed really well in the 18-50mm focal range. It was both sharp and relatively distortion free. Lightroom’s Lens Correction easily managed the slight distortion there was too.

    Things to be careful of

    Remember I said we’d talk about the not-so-good too? It is a touch tricky to twist the lens in order to zoom in past 200mm to get to the 400mm focal length. First, your hand gets a bit “stuck” since anatomically, your wrist only twists so far before you have to reposition in order to continue the twisting motion.

    Second, the lens has what I call a “hiccup” where you need to exert more pressure to push it past this point. I missed a few shots because the twisting motion wasn’t smooth enough and I jerked the lens a bit as I zoomed in from 200mm to 400mm.

    Softness around the edges

    There is a definite softness (or loss of sharpness) at the longer end of the lens, especially when your aperture is wide open, e.g., 400mm at f/6.3. If you crop in too much during post-processing or print too large, you’ll start to see the loss of fine details in your image since they weren’t tack sharp to start. You won’t see this loss of detail in a small 5×7″ print, or if you post to social media – so for many people, this actually won’t be a big issue.

    Tamron 18-400mm lens Review - Riders up

    Riders up at the paddock, Arlington Park IL. Canon 7D Mark II, Tamron 18-400mm lens @ 18mm, f/5, 1/500th, ISO 640, handheld.

    Use the center focus point

    The lens tends to be softest in the corners so sharpness improves if you use your camera’s center focus point. It also improves if you close down your aperture to f/8, f/9, or smaller. Because the lens is not tack sharp all the way through the focal length spectrum, I’m not recommending this lens for super serious wildlife shooters or anyone who likes to print really large. For you guys, I’m going to suggest sticking with a more standard zoom lens like a 100-400mm or 200-400mm. (I apologize in advance for the wear and tear this recommendation will cause your shoulders.)

    If you predominantly shoot wide-angle images, like landscapes, and only occasionally shoot long, this lens will be a good fit for you when you don’t want to carry a ton of gear.

    Final thoughts

    Ultimately there were a number of things I really liked about this lens. The small size and super-zoom focal length make it a very practical tool to have in your bag. At $ 649.00 USD, it’s also a great value.

    However, the softness at the long end of that focal length can become a real issue if you’re not careful. Because of that, I’m cautiously going to rate this lens 3.5 stars out of 5.

    I’d love to hear your opinions too. Have you tried super-zooms lenses? Do they work for your type of photography? Which is your favorite one and how does it compare to the Tamron 100-400mm lens? Please share your thoughts with the dPS community in the comments below.

  • How to Process Real Estate or Architectural Photos with Aurora HDR 2018

    If you’ve ever tried your hand at real estate or architecture photography, you know that these are two of the most complicated forms of photography out there. The challenge is due mostly to having to balance out shadows created by harsh or uneven lighting. Thus, it’s no wonder that High Dynamic Range (HDR) photography is one of the most-used techniques for capturing real estate and architecture photos.

    Before I go any further, let’s make it clear that this article is not about defining what HDR photography is or debating its merits. There is a myriad of arguments for and against HDR, but let’s save those are for another article. For now, let’s talk about Aurora HDR 2018 and how it might help you capture and process better HDR images.

    How to Process Real Estate or Architectural Photos with Aurora HDR 2018

    Simple, intuitive interface

    If you’ve made HDR images using other photo editing programs such as Adobe Photoshop, you’ve probably had trouble figuring out how to use the software. One of the best features of Aurora HDR is that it is very stripped down, presenting you with only a few essential options that you can select to create your image. This greatly reduces your learning curve and makes it easy to get started immediately.

    Use as standalone or with other programs

    Speaking of other photo editing programs, you can use them in conjunction with Aurora HDR. It’s very easy to do. When you install Aurora HDR 2018 you can set it up to work both as a standalone program, or as a plugin for Lightroom, Photoshop, and others.

    You don’t need a tripod

    Historically, you’ve always needed to shoot bracketed images with a tripod to make sure they’re all aligned before merging them into a single HDR image. Not so with Aurora HDR. Thanks to their handy Alignment feature, Aurora HDR can automatically align your bracketed images (more on this in #2 below). This means that you don’t necessarily need to capture brackets with a tripod.

    Of course, your images should be relatively aligned beforehand, but you don’t need the pinpoint accuracy that you used to need with other HDR photo editing programs.

    Macphun Aurora HDR Photo Editing

    Getting started with Aurora HDR

    1. Open Aurora HDR and load images

    When you first open Aurora HDR, you’re presented with a straightforward dialogue box that offers you three options (as seen in the screenshot above).

    a) Open Image – In the very center is a button labeled “Open Image.” You can click on the button to select your images, or drag and drop them.

    b) Batch Processing – If you have multiple sets of bracketed shots that you want to process all at once, drag and drop them into the Batch Processing dialogue box! Aurora HDR is intuitive enough to sort through the batch of files for you and automatically detect and match up your bracketed images.

    Aurora HDR Batch Processing

    c) Open Sample Image – This is a blue hyperlink below the “Open Image” button that you’ll probably only use the very first time you’re getting your feet wet with Aurora HDR. It exists mainly for demonstration purposes.

    2. Set additional settings

    For now, let’s assume you chose to Open Images (or, in the demo screenshots below, Load Sample Images). After doing so, another dialogue box appears with just a few options. The Alignment option is visible, and the others pop up when you click on the “Additional Settings” button.

    Aurora HDR Brackets

    Alignment

    As mentioned above, checking the Alignment box will make sure all of your bracketed images line up properly. This means that you could possibly hand hold your camera while taking bracketed shots. But if you’re shooting a paid job, I’d still recommend shooting on a tripod to make sure you get the right shots, in perfect registration.

    Ghost Reduction

    If you happen to have a moving subject in your HDR brackets, enable the Ghosts Reduction setting. This can minimize the effect of ghosting in which moving objects may appear translucent or ghost-like in your final image. For real estate and architecture photography, you’re unlikely to have moving subjects unless you’re incorporating people in your photo or you can see moving tree branches through a window.

    Aurora HDR Options

    Get to Ghosts Reduction, Color Denoise, and Chromatic Aberration Removal by clicking on the gear icon (seen here in orange).

    Color Denoise

    Reduces the low-light noise in color pixels that can sometimes occur when merging photos together. This option is automatically enabled (as seen above), but you can shut it off if you wish.

    Chromatic Aberration Reduction

    It’s not unusual for real estate or architecture photos to have chromatic aberrations. Luckily, Aurora HDR has an option for minimizing the appearance of the purple and green glow along your image edges that is a clear indication of chromatic aberration.

    3. Merge your photos

    After checking the settings, click on the blue Create HDR button, and wait for your images to merge. This is perhaps the only downside to Aurora HDR (or, the whole HDR process in general). It takes a minute or two for the images to be merged together, so sit tight!

    4. Select a preset or edit with the tools

    Once Aurora HDR is done merging your photos, you’ll be presented with a more robust workspace where you can edit your HDR image further.

    At the very bottom of the screen are a bunch of presets that you can choose to automatically adjust your image to a certain style. The Basic presets are selected by default, but if you click on the yellow “Categories” hyperlink, a bunch more will appear. For real estate, the Architecture presets are particularly helpful. Once you select a preset, you can adjust the amount to lessen or magnify the effect to your taste.

    If you prefer to manually edit the photo with or without presets, use the far right panel where you’ll find basic photo editing tools. Scroll down to find even more editing tools such as Adjustment Layers and Dodge and Burn (more on these below).

    aurora HDR

    Preset categories here.

    Aurora hdr

    Lessen the effect of a preset by lowering the slider.

    5. Add Adjustment Layers

    Another fantastic feature of Aurora HDR is the ability to easily add Adjustment Layers in order to make targeted, non-destructive edits to your image. This is extremely useful in real estate and architecture photography, as you often need to make color and tonal adjustments to your image without inflicting permanent changes on the pixels.

    For example, the image below illustrates the addition of an Adjustment Layer that targets the blue tinge in the staircase and chairs in the middle of the image, with the goal of color correction. Adjustment Layers also exist in Photoshop, and they function very similarly in Aurora HDR. The best part is that it is much more intuitive and easier to find in Aurora HDR than they are in Photoshop.

    Aurora HDR Adjustment Layers

    Adding an Adjustment Layer for local color control in selected areas.

    6. Dodge and Burn

    If you’ve upgraded to the brand new Aurora HDR 2018 version, you’ll find a couple of essential real estate photo editing tools that are much handier to access: Dodge and Burn Tools! If you’re unfamiliar with dodging and burning, you can read up on these photo editing processes in this dPS article.

    In short, dodging helps you brighten targeted areas of an image while burning lets you darken them. Both techniques are essential for real estate photography retouching. In the new version of Aurora HDR, these tools are easily accessible in the right-hand panel. Simply scroll down to the “Dodge and Burn” panel and click on “Start Painting.” This will activate a few settings right above your image.

    Aurora HDR Dodge and Burn

    Use the Dodge and Burn tools to do special localized tone control in your image.

    In Conclusion

    If HDR photography sounds interesting to you and you’re looking for an easier way to post-process your images, give Aurora HDR 2018 a shot! Its intuitive, clutter-free interface is relatively easy to learn and you can begin enhancing your real estate photos in no time.

    Are Photographers Artists? Let's Discuss

    I took this image while on a trip out west to the Grand Teton Mountains and Yellowstone National Park with my family and about 50 other people. We were driving towards our next lodge, past the mountains and the Snake River where we would be rafting the next morning when I became rather fascinated with the scene that lay before me.

    Having never seen mountains before in my life – besides seeing the photographs online and in movies – I was awestruck. Immediately I grabbed my camera and began snapping away, fighting the glare of the window while also paying careful attention to the meter in my viewfinder. After I had arrived home about a week later, I was culling the images I had taken on the trip. Almost immediately, this became my favorite.

    Are Photographers Artists? Let's Discuss

    This image was also taken in the mountains, another favorite of mine, was a much more thought out composition. Our tour guide had told us that we would be stopping to see a church with plenty of photographic opportunities. Almost immediately I knew the shot that I wanted.

    I set up my tripod ever so perfectly, did a few test shots to make sure my exposure was right-on, and then explored the area, leaving my camera in position until everyone else was back on the bus. Although I knew I would be the last back in my seat, I knew it would be worth the wait. And it most definitely was, for as everyone else was loading on the bus, the scene was almost completely empty. I took three exposures of the scene, bracketing it just in case the light had changed, and got back on the bus.

    Are we artists or photographers?

    The reason I’m telling you about these two images is not to make you jealous of my amazing adventure with my family. Rather, I tell you about these to get you thinking. You see, since the days of Ansel Adams, there has been a major debate regarding whether or not photographers should be considered artists.

    Ansel Adams himself had struggled with this, having been amongst many other photographers in the beginning of the craft who used soft-focus lenses to create images which looked less like reality and more like paintings. Why? Because photography as a form of art was not taken seriously at the time and to make it among other artists, you had to make your images look like they were painted, not photographed.

    Do we document or make art?

    So, this begs the question: as photographers, are we crafting works of beautiful art? Or are we simply documenting the world around us with some special – yet easily done by others – ability?

    Are Photographers Artists? Let's Discuss

    One argument that is commonly brought to light against photography being an art form, is that anyone can do it. There is no need for special gear, no apprenticeship is mandated; you do not even need to take a class to learn photography. Most professional photographers haven’t taken a formal education.

    But if this is the case, why do we bother honing our skills? What is the point of constantly learning new compositional techniques, new ways of post-processing? Why do we bother to buy “better” camera bodies, new lenses, sturdier tripods, if our craft is not considered a form of art? If anyone can do it, what is the point of buying a $ 4000 Nikon D850 that everybody is drooling over?

    Because not everyone can do what we do

    Are Photographers Artists? Let's Discuss

    Yes, everyone can be a photographer; every random guy on the street can pick up a camera – or use his smartphone – and take a pretty picture of the sunset. Just look on Instagram and you will see what I mean. But that can be said of painters, sketch artists, etc., as well. Everyone can be an “actual artist” as well. I can pick up a paintbrush, slap some paint on a canvas, and call it modern art. I can draw a single line in the center of a 20×30 foot canvas, hang it in a prestigious art gallery, and sell it for millions. It’s been done before, and it will continue to be done. So, the question is, is this still art?

    So if you tell me that painting a single stroke on a canvas is art, then you must also allow me to tell you that photography is art. Otherwise, you are saying that everyone can do photography yet not everyone can paint a line, correct?

    Are Photographers Artists? Let's Discuss

    Photographers as documentarians

    There is also the argument that, as photographers, we are simply documenting the world. We are merely at a location at the right time; we are lucky.

    But if we are lucky, how can you explain the countless hours we spend sitting in one spot, waiting for the light to hit, only for the photograph to not turn out as we had hoped. And then we go back to that same location and wait even longer, hoping that the light will turn out this time. Then when it doesn’t, we continue to go back until finally, that light works out. Is that truly luck?

    Are Photographers Artists? Let's Discuss

    Yeah, just like painters we could probably find a way to Photoshop in some light, replace the sky in the scene to something more visually appealing, and then call it a day.

    It’s more than just luck

    To say, however, that we are lucky with almost all the shots that we obtain only undermines the countless hours, months, years that we have spent attempting to get better at our craft. Studying compositions of the great photographers before us, buying tutorials of the photographers we admire in hopes that they know something we do not – that does not constitute luck.

    Yes, as photographers, we rely on chance. We rely on the weather turning out how we had hoped and the scene we are looking for to be found. At the same time, however, we must learn to adapt to our surroundings, and to our situation. If we are to make it as photographers, we must learn that not everything will turn out as perfectly as we had hoped.

    Are Photographers Artists? Let's Discuss

    And at that point, we can either come back to the location later or find a way to make it work. We must use our creativity to craft a scene that will be just as good, if not better, than the one we had originally planned in our head.

    Looking back at the photographs I had taken while out west, I must ask myself, am I an artist?

    What does the master say?

    I think Ansel Adams had it right when he said:

    “A photograph is made, not taken. A photograph is not an automatic recording, neither is it an accident. It is a concept, a vision of the world translated into shades of gray, communicated in terms of simple devotion to the medium – a statement of the utmost clarity and perfection possible…”

    Are Photographers Artists? Let's Discuss

     

    Art has always been subjective. It doesn’t matter if you are taking a picture of your cat or a grand vista in Iceland. In my opinion, if you have an opinion, a mood or emotion, that you are trying to convey to the world through your imagery, then you are an artist.

    So, the question is, do you consider yourself to be an artist? Let’s discuss in the comments below.

  • Tips for Aerial Photography from Small Planes and Drones

    At its heart, good photography is about showing people views of the world they would not otherwise see. That might be; places your viewers have not visited, impossible ways of seeing to the human eye such as long exposures and night photography, but most often this novelty comes in the form of a different perspective. Even familiar scenes and objects can make compelling photographic subjects if we are willing to explore them from new angles.

    Tips for Aerial Photography from Small Planes and Drones

    Aerial photography is one of my favorite ways to provide that novel perspective. I’m fortunate to spend a lot of time in small planes. My life in Alaska is full of flights in bush planes to remote places in the state. While only occasionally do I fly specifically to make aerial images, I find simply going to and from different locations provides ample opportunity.

    The second way I frequently use to access an aerial perspective is by flying drones. While both techniques get me the elevation I want, the photographic experience is very, very different. The two methods, planes and drones, require very different ways of thinking about image-making.

    Tips for Aerial Photography from Small Planes and Drones

    Here are a few tips to improve your aerial photography images, whether you are shooting from a plane or using a remote drone.

    Airplanes

    While big passenger jets are great for getting us from one place to another quickly, they are lousy photography platforms. Sure, I’ve made some images from jet windows, but they inevitably follow the same formula. There’s an airplane wing in the foreground with some sunset or mountain beyond. It gets old. Plus the perpetually fogged or scratched windows will destroy your image quality. Except for the occasional phone snap, I rarely bother with it anymore.

    Small, single-engine planes, however, are a different story and can be an amazing platform for creative aerial photography.

    Tips for Aerial Photography from Small Planes and Drones

    Sharpness

    Attaining a sharp image is a major challenge because airplanes are vibration-filled nightmares. Here are four things to help you improve sharpness:

    1. Use a fast shutter speed. I like anything over 1/1000th of a second.
    2. Don’t brace your lens or arms on the plane. Hold your camera and elbows free of the window. If you touch the plane, the vibrations will be transmitted straight into your camera. I tuck my arms against my sides and hold the lens an inch or so away from the window glass.
    3. Focus at infinity. I often shoot manual focus from the air and pre-set my focus point to infinity. Everything you are seeing from the air will be in focus when the lens is set to infinity, so don’t even bother with autofocus.
    4. Shoot wide open. The depth of field is not a problem from a 1000 or meters from your subject. So a take advantage of the extra shutter speed provided by your fastest f-stop.

    Lens Choices

    Tips for Aerial Photography from Small Planes and Drones

    When flying 100+ mph at low altitude, the landscape passes very quickly. If you don’t act quickly, you’ll miss the shot. That’s why I like zoom lenses for aerial photography. I can quickly compose with different focal lengths, without having to change lenses or cameras. I favor a wide to moderate zoom. A 24-105mm or similar lens is about right.

    Communication

    Usually, in a small plane, you’ll be in direct communication with your pilot, who might be willing to help you out with your photography. When I’m flying over something interesting, but a wing or strut is in the way, I’ll often simply ask the pilot to tip a wing one way or another. Pilots are often happy to accommodate you.

    Tips for Aerial Photography from Small Planes and Drones

    You can also ask them to make slight turns, or even circle if there is something particularly compelling. If you’ve chartered a flight for photographic purposes, feel free to ask for what you want.

    I recommend talking to your pilot ahead of your trip to discuss what kind of images you want, and how he or she might be able to help you. If it is a photography-specific flight, you may even be able to remove windows or doors from the plane.

    Tips for Aerial Photography from Small Planes and Drones

    Remember your pilot is the final judge of what is acceptable in terms of safety and time. If they say they can’t do something, they can’t. Don’t push them into something with which they aren’t comfortable.

    Composition

    There are almost as many ways to shoot from an airplane as there are from the ground so any discussion of composition runs the risk of leading us deep into the photographic weeds. However, the general rules of landscape photography still apply. Remember depth, foregrounds, and the way lines connect the image.

    Tips for Aerial Photography from Small Planes and Drones

    Some shots from the air could be details of the landscape below, but more often they will be sweeping landscapes. I like to place elements in the frame that guide the eye through; a river, a mountain valley, or a highlight like a lake or patch of colorful ground.

    The altitude at which you are flying will also dictate your options. When making aerial images of mountain environments (my usual subject) I prefer the plane to be below the level of the surrounding peaks. This perspective still provides a sense of grandeur, while maintaining the unique aerial perspective. Ask your pilot if you can fly lower or higher, and they may be able to help you out if conditions are safe.

    Drones

    Flying a remote copter or drone is a very different experience from being up high yourself. There are advantages, but also some drawbacks.

    First the drawbacks. Most consumer grade drones limit you to one focal length. Without the ability to zoom or change lenses, most drone shots tend to have the same wide-angle look. To change the scene, you’ve got to move the drone. Drones also have limited ranges, elevation capabilities, and at times, limiting regulations.

    Tips for Aerial Photography from Small Planes and Drones

    Some locations, like national parks in the United States (and many other countries) are off-limits for drones. Range limitations also mean that you have to get yourself close to your desired subject. So if you want to make images of some remote, or difficult to access location, you’ll still have to do it on the ground.

    The advantages, however, are many. Cost is a big one. For the price of a couple hours charter of a small plane, you can buy a decent drone, literally. Flexibility is another. If you want to go make some aerial photos, you simply do it, no waiting around for a pilot or plane charter. If the light is right, you just go fly.

    The biggest advantage for me, though, is composition flexibility. You can create an image from a few meters off the ground, to a couple hundred. You can also spend the time necessary to get the composition right. The drone sits still when you want it to, or you can adjust to your heart’s desire.

    Composition

    I like to fly my drone fairly low. I find the combination of altitude and wide angle lenses make everything look less dramatic and smaller if I’m flying too high. 20-30 meters off the ground is probably my favorite height, but of course, it varies on where I’m flying and the image I’m creating.

    Remember to take advantage of the many camera angles drones allow. Shooting straight down is almost impossible from a plane. But with a drone, it’s as easy as angling your camera.

    Playing with lines and patterns is a drone specialty, so take advantage of the way the world looks from above. Play with dividing your images into parts using the natural variations in the landscape. Trees from above, for example, create a starburst pattern, not a typical way humans see a forest!

    Tips for Aerial Photography from Small Planes and Drones

    The flexibility provided by drones is extraordinary. Don’t be afraid to experiment with aerial images of places a plane could never fly.

    Drone Warning

    Follow the rules! Flying a drone in a dangerous area like around airports, or at the scene of an emergency is not only irresponsible it can be life-threatening. Be aware of the laws surrounding drones, and fly only in areas where it is allowed, and at permitted elevations.

    Lastly, be respectful of others. Don’t fly over private property if you don’t have permission, and be aware of how your flight is impacting the experience of others. Simply put, don’t be a jerk.

    Tips for Aerial Photography from Small Planes and Drones

    Conclusion

    Aerial photography is a gateway to new ways of seeing. Whether you are shooting from the passenger seat of a Cessna or from your phone screen using a drone, there are abundant opportunities to make new and exciting images. Explore it and share with me what you make!

  • New Ayesha Curry, Michael Mina San Francisco Hot Spot International Smoke, A Contemporary Take on Barbecue

    International Smoke
    International Smoke, San Francisco’s newest restaurant in the lobby of the Millennium Tower

    International Smoke

    Last night mrsth, the four kids and I had the opportunity to dine at San Francisco’s newest restaurant hot spot from celebrity chefs Ayesha Curry and Michael Mina, International Smoke. The restaurant is the latest lobby tenant in the great leaning tower of Millennium at 301 Mission Street in San Francisco’s SoMA district.

    Only a week old, International Smoke is already solidly booked for months. The good news though is that they take walk ins at the bar and have several tables that can seat up to six in the bar. Before getting into my thoughts on the food, I will say that with a big family (six of us) one of my frequent disappointments is when too many diners are crammed into a small table at a bar. In the case of International Smoke this is not the case for their 6 tops. They are large, roomy and comfortably accommodated our large group. There are also several 4 tops in the bar and of course you can also dine seating at the bar itself. We luckily got the last table in the bar last night just before dinner service started at 5:30 pm.

    The bar also has several televisions which can be viewed from almost every seat and which were appropriately tuned in last night to the Warriors 124-116 win over the Philadelphia 76ers during dinner.

    Although barbecue features prominently on the International Smoke menu, it would be misleading to call it a “barbecue” restaurant. While definitely a place for carnivores, the barbecue has a more modern and international presentation and the menu also includes many non-barbecue offerings.

    Many of the offerings are also fairly theatrical in nature, not quite what you’d find at say Edith’s down in Cabo San Lucas, but they incorporate smoke prominently to give you your fun little dinner show to go along with the food. In addition to serving two of our dishes (the smoked burrata and instant bacon) in glass encased smoke filled canisters, they prepare the Wagyu Shaking beef in a hot skillet tableside and use a cooking torch to caramelize the sugar while serving the ribs. It’s always nice to get a little extra pizzaz at the table when taking the kids out.

    So let’s get into the cocktails and food.

    I started off the evening with the Curry Up Now cocktail, because, well Steph Curry right? Plus I like bourbon. The drink is made with Wild Turkey 101 Bourbon, Madras Curry, Amontillado Sherry, and Corazon Bitters. It was served in a beautiful Waterford crystal style tumbler over one of those giant ice cubes you get at fancy bars these days. Although I’m not sure that Steph drinks one of these things every day at cocktail hour, it was a well balanced, slightly sweet bourbon based cocktail and it worked just fine for me.

    We also tried the Rhinestone Cowboy, made with Hangar One Kaffir Lime Vodka, Espolòn Blanco Tequila, and Coconut Calamansi, refreshing served over that nice soft crushed ice that you also find at fancy bars these days.

    WAGYU SHAKING BEEF, International Smoke

    International Smoke’s Wagyu Shaking Beef

    Our first dish was the aforementioned Wagyu Shaking Beef, cooked in that black hot skillet tableside. It comes with lettuce and you make little lettuce wrap taco like things. This was a favorite. The beef was delicious, cooked slightly rare and very juicy. They added a marinade to the beef as it was cooking. It’s Wagyu so it’s bound to be tasty, but as expected for things labeled Wagyu, it’s also expensive and you wish you got a lot more of it. I would probably order this again, and probably again, and again.

    Classic American Wedge, nternational Smoke

    Smoked, Burrata, International Smoke

    Next up was International Smoke’s take on an all time classic, the wedge salad. It’s prepared cut in half with everything served up on top. Again, a little small, but delicious and a beautifully balanced mixture of dressing, bacon, onions and tomatoes.

    The burrata was served at the same time as the wedge and came in the previously described smoke filled canister. The aha moment comes as the canister lid is lifted and the smoke disappears into the air, leaving you with a very creamy piece of smoke flavored cheese. The brussel sprouts went well with the cheese and it was a nice bit of salad before getting into the meats.

    We also ordered a mixed pickle jar which is a myriad of pickled vegetables. At $ 6 it felt like a bargain on the menu and if you like pickled veggies I’d recommend it. I liked the pickled onions the best.

    Kalua Style, Instant Bacon, International Smoke

    The Kalua “Instant Bacon” is more like a pork bun than anything, served in another one of those smokey canisters with the big reveal — a very rich piece of pork served in a bun — again very tasty, but two to a plate a bit on the small side.

    Smoked Pork Shoulder, International Smoke
    Smoked Pork Shoulder, International Smoke

    We tried two orders of the Trio Sampler smoked pork shoulder. This consisted of an American pulled pork slider, Cuban Mojo Tostones and Korean Scallion Crepes. The American pulled pork slider was the favorite (especially with the kids) but I liked the Cuban Mojo Tostones the best myself. I did not care for the Korean Scallion Crepes.

    Double Duck Wings, International Smoke
    Double Duck Wings, International Smoke

    The double duck wings were up next. These were ok but my least favorite dish of the evening. They were pretty basic and a bit bland. The sauce they came in was tasty and interesting, but I would not order this again. We didn’t eat most of this dish and took it home with us in a box. I tried it again for breakfast this morning and it tasted a little better cold, but still not a favorite.

    Smoked Pork Ribs, St. Louis Cut, International Smoke
    Smoked Pork Ribs, St. Louis Cut, International Smoke

    Up next was the main event, a full slab of the smoked pork ribs. As previously mentioned, they bring these out with a cooking torch and torch the sugar on the ribs right there tableside. As far as ribs go these were perfectly adequate but nothing spectacular. The ribs probably had too high a bar to live up to in my mind though. When I read “St. Louis Cut” on the menu the only thing I could think about from then on was how much I love the ribs at Pappy’s in St. Louis. Those juicy, beautiful bone dripping ribs at Pappys, or if not Pappy’s at least all of the great sauces at St. Louis’ latest downtown barbecue spot Sugarfire with one of the best neon signs ever.

    International Smoke’s ribs were just fine, but they were not as good as what you’d get at the best spots in St. Louis, or Kansas City, or Texas or Alabama. Again, I’m spoiled having experienced some spectacular barbecue over the years though. I probably should have known San Francisco celebrity chefs would be no match for hardcore pitmasters who’ve been doing their thing for 30 years.

    Along with the ribs we ordered the french fries, which were pretty much the same basic fries you’d get anywhere and three sides of the mac and cheese.

    Smoked Rib Tip Mac and Cheese, International Smoke
    Smoked Rib Tip Mac and Cheese, International Smoke

    The mac and cheese was interesting — actually it was my favorite dish of the evening, but I’m a big mac and cheese fan. It’s served with rib tips and cornbread crumble on top. It was very good. I was very happy with this dish… but… would I rather have International Smoke’s mac and cheese or the buffalo chicken mac from Homeroom? See, again, it’s a high bar in my opinion, so while I was perfectly happy with this dish it was probably doomed from the start in my mind.

    Anyways, there you have it. We ordered too much food for dinner so didn’t have room for dessert. Apparently my youngest daughter Kate was promised ice cream earlier in the day, however, so we stopped by Fenton’s on the way back home to pick up a half gallon of toasted almond. I’m sure International Smoke’s ice cream is probably just fine, but I doubt they hold a candle to Fentons. ?

  • Full Frame or APS-C for Wildlife Photography – Which is Best?

    Choosing between a full frame or cropped sensor camera for wildlife photography can be a tough decision. Both options offer their own benefits, so choosing between the two can cause quite the headache. Lots of photographers have their opinions, but choosing what’s right for your own use will largely come down to your personal style of shooting. So let’s break it down.

    FX full frame and APS-C - Full Frame or APS-C for Wildlife Photography - Which is Best?

    The Basics

    Most modern camera companies use either full frame or APS-C (crop) type sensors in their DSLR (and mirrorless) cameras. The former is often classed as the professional standard, with the sensor size being a close replica to that of a 35mm film negative.

    APS-C on the other hand, is roughly two thirds the size of a full frame sensor, resulting in the field of view being multiplied by a factor of 1.5-1.6x that of a standard full frame model. These sensors feature mostly in the lower tiered offerings by camera companies, with the chips being less expensive to produce.

    Full Frame or APS-C for Wildlife Photography - Which is Best?

    Working with APS-C means you can travel lighter.

    Crop Factor

    For APS-C models one of the largest benefits for wildlife photographers is that of the additional crop factor. The 1.5-1.6x magnification of your optics can be hugely beneficial when working out in the field, trying to photograph small birds or distant wildlife.

    The crop factor also allows you to get a similar angle of view with a far smaller lens, helping to reduce the gear you need to carry while still giving you great telephoto reach. This is something a lot of photographers find as a huge benefit, as they can minimize the size and weight of the gear they need to carry out into the field.

    For example, a 70-200mm lens on a 1.5x crop-factor body gives you the equivalent of a 105-300mm lens. A perfect compact wildlife setup.

    APS-c cameras crop factor can be a great benefit for wildlife photography - Full Frame or APS-C for Wildlife Photography - Which is Best?

    APS-C cameras crop factor can be a great benefit for wildlife photography.

    ISO Sensitivity

    One of the large benefits of a full frame camera is that of better image quality when shooting at high ISO. The larger sensor means in the individual pixels (and light sensitive photo sites) are larger than those on an APS-C type camera. This means as a general rule they are more sensitive to light, allowing cleaner noise-free images at high ISO settings, something that is fabulous when trying to work and photograph wildlife in low light conditions.

    Now with modern sensor advances, APS-C models of the past few years have come up leaps and bounds in terms of ISO performance – easily being useable to ISO 6,400. But, if low light usability is key for the subjects you’re working with, a full frame camera is still king.

    Full Frame or APS-C for Wildlife Photography - Which is Best?

    APS-C cameras can still make great results at a high ISO.

    Depth of Field

    When comparing that of full frame sensors with APS-C models, one extra thing to consider is the depth of field characteristics and how areas are rendered out of focus.

    With the smaller sensor in APS-C models, they give the effect of having a larger depth of field at equivalent apertures when compared to a full frame camera. This means that if you are going after images that render clean bokeh and have a very restricted depth of field to isolate and direct your viewer’s attention to your subject, a full frame model will be better suited.

    Full Frame or APS-C for Wildlife Photography - Which is Best?

    Full frame cameras are great for shallow depth of field effects.

    Of course, if you do a large amount of macro work and want to maximize the depth then an APS-C camera might be right up your alley.

    Resolution

    In the past few years, technology has advanced in resolution steadily, with cameras being introduced that have high 36-42 megapixel sensors. For the most part, ultra high-res sensors have been used in the realms of advertising and commercial photography for years. But of course, now having been brought into DSLRs they offer photographers more flexibility.

    The high resolutions models are mainly full frame sensors, as packing huge numbers of pixels onto small sensors can heavily impact their quality. The FX models that have high resolution offer a unique advantage, as they make the most of the benefits of full frame models, yet offer the ability to crop heavily to replicate the crop factor of those advanced APS-C DSLRs.

    Often a disadvantage is that these high-resolution cameras are slower in terms of frames per second, due to internal data writing limitations. But this is advancing all the time, especially with new forms of storage media offering faster write times.

     

    Full Frame or APS-C for Wildlife Photography - Which is Best?

    High megapixel full frame cameras offer great all-around performance.

    The full frame camera with a high-resolution sensor can be somewhat of a perfect compromise for those wanting the ISO performance and bokeh rendering benefits of full frame, combined with the ability to crop. Providing, of course, that they aren’t to hung up on needing blazing fast frame per second shooting rates.

    Cost

    One factor that always plays a part when looking to buy new gear is that of cost. Full frame bodies by their nature are more expensive, with the chips inside being harder to engineer and more expensive to produce. APS-C cameras are often found at lower price points, but this depends on the body design and extra features such as speed, construction, and technologies implemented.

    Some full spec APS-C cameras are significantly more expensive than full frame models due to the advanced autofocus features, frame rates, and build quality.

    So what to choose?

    For wildlife photography, it largely depends on your target subjects.

    If you love photographing birds and small creatures, a high-end APS-C body that combines the crop factor with speed will serve you well. The crop factor is also a huge benefit if you want to get a longer telephoto reach without having to shell out for ultra-expensive super telephoto lenses. Meaning you can have a small set up that offers a good compromise for most situations.

    If you want to truly get the best performance and quality, full frame models are where to look. The high-resolution sensors and excellent low light performance make for great image quality. However, of course, you’ll also need to invest in the best optics to make the most of them.

    These are both costly and a large burden to carry around. However, if you want the best quality imaginable that’s what it takes. For those starting out investing, an APS-C model would be my recommendation. Save your funds to buy decent quality lenses, as these will largely make more of a difference to your images than a single stop of ISO or a slightly higher resolution sensor.

  • How to Use Framing in an Urban Environment

    Photographers have long developed different classifications to pair with the design and execution of a photograph – lines, shape, texture, light, framing, contrast, just to name a few. For example, leading lines appeal to a viewer’s natural tenancy to trace line into a photograph. Sharp lines are used to grab attention and organic lines create a peaceful atmosphere.

    Other composition techniques like the Rule of Thirds require a photographer to mentally break down an image to evaluate balance. Low and high perspective alter the way a viewer sees the world and symmetrical/asymmetrical elements highlights the quirky beauty of life. The technique we’ll have a quick look in this article, demonstrates the power of framing, especially in an urban environment.

    How to Use Framing in an Urban Environment

    What is framing?

    Framing in photography creates a self-contained image, like a photo-within-a-photo effect. As photographers, we are used to seeing the world through the frame of a viewfinder. We constantly evaluate what we’ll keep in an image and what we’ll exclude. We deliberately apply perspective, aim, zoom and positioning techniques to construct our photographs – sometimes without even noticing.

    By cradling the subject in a balance of space and line, a frame is created, not dissimilar to the photo frames you’d find on your shelf at home.  Essentially, you are crafting a frame within a frame to deliberately bring focus to a subject, adding narrative and the unique experience of voyeurism that photography affords.

    How to Use Framing in an Urban Environment

    How do I frame a photograph?

    For such an effective technique, framing has plenty to offer. It makes use of strong design skills, adding an extra layer to an image to create more depth.  Framing can also be used to obscure more mundane areas of a scene, boosting the efficacy of a photograph when viewed by others.

    Composing an image by making use of framing is fairly straightforward. Start out searching for windows and doors as they are the most abundant frames in an urban environment. You’ll find that windows and doors, when photographed, contain their own little ecosystem within the one image. This is great for capitalizing on both content and narrative, almost like reading a window in a comic strip!

    Frame shapes

    Square or rectangular frames are probably the first things that leap to mind when someone considers framing. Doorways and windows are a great way for emphasizing a subject or depth, but they are not the only options and framing is not limited to squares or rectangles.

    The image below proves how versatile the urban environment can be for artificial framing. The image was taken from the floor of a train station, lens pointed to the floor above. The darkness of the building structure is silhouetted against the blue sky, forming a crescent shape. The frame draws attention to the contrast of the architecture against the sky but also cradles the form of a human passing by.

    This photo was taken by chance in a late night shopping district. The framing of the man emphasizes his presence but also isolates him from the rest of the landscape.

    For this image, I aimed to align a gap in the cage with the cat’s face. The slight distortion caused by the lens draws the center square closer to the viewer’s eye. Framing isn’t always a split-second discovery, taking the time to assess a situation and respond creatively can be just as effective as shooting from the hip.

    How to Use Framing in an Urban Environment

    Shattered windows in rundown urban landscapes offer beautifully detailed landscapes complemented by an informed framing technique.

    Keep it real

    Framing can be really effective for highlighting specific areas of a photograph. However, it’s important to keep in mind that not every photograph needs framing. Some images are much more effective when they stand alone. Like most photography, you need to be versatile and trust your instincts.

    While lining up a perfect shot through a fence can be effective, make sure to be aware of your surroundings too. Don’t focus so heavily on framing that you sacrifice other photographic opportunities. You don’t need to force a frame on an image, so don’t overthink it. You want natural images that are enhanced by a frame, not poor images that require a frame to garner interest.

    Just stay open to the idea of framing and gather enough experience to recognize a framing opportunity when one presents itself. This way, opportunities tend to reveal themselves rather than you having to force them out of hiding.

  • How to Understand Pixels, Resolution, and Resize Your in Photoshop Correctly

    Size, resolution, and formats… What do pixels have to do with it?

    Do you buy your camera based on its number of megapixels? Are you having problems sharing your photos online? Does your print look low quality even if it looks great on the screen? There seems to be a lot of confusion between pixels and bytes (image size and file size), quality and quantity, size, and resolution.

    So let’s review some basics to make your life easier, your workflow more efficient, and your images the correct size for the intended usage.

    How to Understand Pixels, Resolution, and Resize Your in Photoshop Correctly

    This image is sized to 750×500 pixels at 72 dpi, saved as a compressed JPG which is 174kb. Let’s look at what all that means.

    Is resolution the same as size?

    One of the biggest misunderstandings comes from the concept of resolution. If this is your case, believe me you’re not alone.

    The problem is that resolution can refer to many things, two of them relate to the problem at hand. Further on I’ll explain these two resolution concepts, however, they have one thing in common that I need to clarify first. They both have to do with pixels.

    You’ve probably heard a lot about pixels, at least when you bought your camera. This is one of the most available and “valued” specs on the market so I’ll start there.

    What is a pixel?

    A digital photo is not one non-dividable thing. If you zoom in far enough you’ll see that your image is like a mosaic formed by small tiles, which in photography are called pixels.

    Pixel grid - How to Understand Pixels, Resolution, and Resize Your in Photoshop Correctly

    The amount of these pixels and the way they are distributed are the two factors that you need to consider to understand resolution.

    Pixel count

    The first kind of resolution refers to the pixel count which is the number of pixels that form your photo. In order to calculate this resolution you just use the same formula you would use for the area of any rectangle; multiply the length by the height. For example, if you have a photo that has 4,500 pixels on the horizontal side, and 3,000 on the vertical size it gives you a total of 13,500,000. Because this number is very unpractical to use, you can just divide it by a million to convert it into megapixels. So 13,500,000 / 1,000000 = 13.5 Megapixels.

    Pixel density

    The other kind of resolution is about how you distribute the total amount of pixels that you have, which is commonly referred as pixel density.

    Now, the resolution is expressed in dpi (or ppi), which is the acronym for dots (or pixels) per inch. So, if you see 72 dpi it means that the image will have 72 pixels per inch; if you see 300 dpi means 300 pixels per inch, and so on.

    The final size of your image depends on the resolution that you choose. If an image is 4500 x 3000 pixels it means that it will print at 15 x 10 inches if you set the resolution to 300 dpi, but it will be 62.5 x 41.6 inches at 72 dpi. While the size of your print does change, you are not resizing your photo (image file), you are just reorganizing the existing pixels.

    Imagine a rubber band, you can stretch it or shrink it but you’re not changing the composition of the band, you’re not adding or cutting any of the rubber.

    Pixel Density 72dpi - How to Understand Pixels, Resolution, and Resize Your in Photoshop Correctly

    Pixel Density 300dpi - How to Understand Pixels, Resolution, and Resize Your in Photoshop Correctly

    In summary, no resolution is not the same as size, but they are related.

    So quantity equals quality?

    Because of the aforementioned correlation between size and resolution, a lot of people think that megapixels equal quality. And in a sense it does because the more pixels you have to spread out, the higher the pixel density will be.

    However, on top of the quantity you should also consider the depth of the pixels, this is what determines the amount of tonal values that your image will have. In other words it is the number of colors per pixel. For example, a 2-bit depth can store only black, white and two shades of grey, but the more common value is 8-bit. The values grows exponentially so for example with an 8-bit photo (2 to the power of 8 = 256) you’ll have 256 tones of green, 256 tones of blue, and 256 tones of red, which means about 16 million colors.

    This is already more that the eye can distinguish which means that 16-bit or 32-bit will look relatively similar to us. Of course, this means that your image will be heavier even of the size is the same, because there is more information contained in each pixel. This is also why quality and quantity are not necessarily the same.

    Therefore quantity helps, but also the size and depth of each pixel determine the quality. This is why you should look all the specs of the camera and its sensor and not just the amount of Megapixels. After all, there’s a limit to the size you can print or view your image, more than that it will only result in extra file size (megabytes) and no impact in the image size (megapixels) or the quality.

    How to choose and control image size and file size?

    First of all, you need to choose the outlet for your photo, there is a maximum density that you need. If you are going to post your image online you can do great with only 72 dpi, but that is too little for printing a photo. If you are going to print it you need between 300 and 350 dpi.

    Of course, we are talking about generalizations because each monitor and each printer will have slightly different resolutions as well. For example, if you want to print your photo to 8×10 inches you need your image to have 300dpi x 8″ = 2400 pixels by 300dpi x 10″ = 3000 pixels (so 2400×3000 to print an 8×10 at 300dpi). Anything bigger than that will only be taking up space on your hard drive.

    How to resize in Photoshop

    Open the menu for the image size and in the popup window, you need to tick the Resample Image box. If you don’t activate “resample” you will only be redistributing the pixels like I explained at the beginning of the article.

    You can also choose to tick the Constrain Proportion if you want the measure to adjust according to the changes you make. So the width adjusts when you change the height and vice versa.

    How to Understand Pixels, Resolution, and Resize Your in Photoshop Correctly

    8×10 inches at 300 ppi, this is the size needed for printing an 8×10. Notice the pixel size is 3000 x 2400.

    750×500 pixels at 72 ppi. This is web resolution and is the exact size of all the images in this article. The size in inches is irrelevant when posting online – only the pixel size matters.

    On the top of the window, you’ll also see how the file size changes. This is an uncompressed version of your image, it’s the direct relationship I explained in the first part of the article: fewer pixels means less information.

    How to Understand Pixels, Resolution, and Resize Your in Photoshop Correctly

    Now, if you still want to change the file size without resizing anymore, you have to do it when you save the image. Before saving your photo you can choose the format you want:
