7 Non-Photography Items Which No Travel Photographer Should Leave Home Without

27 Aug

It’s fair to say that as a travel photographer you can never be 100% prepared for everything. There are so many different scenarios and variables that can affect your photography and your journey that you simply can’t predict. But over time you will begin to learn techniques that will help you be able to tackle the issues you’ll encounter.

Part of this is your list of equipment. While the obvious photographic equipment might seem straightforward, there are also a number of non-photographic items that will begin to make it on your list. As you will discover over time they can also be invaluable. Here are seven of my must-have items that might also help you along the way.

7 Non-Photography Items Which No Travel Photographer Should Leave Home Without

#1 – Plastic Bag and a Rubber Band

It doesn’t matter how well you prepare and how many times you check the weather forecast, at some point every travel photographer will get caught in the rain. Most times you can avoid you and your camera equipment getting wet by trying to wait it out under some shelter. But sometimes you can’t or more importantly, you still want to photograph. After all, rain can provide wonderful reflections on the surface of pavements and roads not to mention people with umbrellas that can really help tell a story.

So to avoid getting your camera wet, simply take an ordinary plastic bag and cut a hole big enough for your lens hood to fit through. You want roughly half of the lens hood sticking out and the hole in the bag should be a tight fit. Put your camera in from the top of the bag (as if you were putting shopping in it) and stick the lens with the hood attached through the hole. Put the elastic band around the bag near the hole to keep it in place and voila you have created a bag to keep the rain off your camera.

When you want to shoot with your camera simply put your hand in the bag and hold the camera inside. Sure you can probably find an expensive version that you can buy, but why waste money when you can make it yourself?

#2 – A Face Towel

If you ask me what is the one non-photographic item that I always carry with me, it’ll be a small face towel. I have lost count of the number of times that I have used a towel in different scenarios. Whether it’s to wipe my camera dry after getting water, mud, or anything else on it, or wiping my face when I’m hot and sweaty (it’s amazing how much better you feel when you can simply wipe your face with a clean towel when you are out and about all day), wiping my finger when I have cut myself, or even just wiping a bench dry after rain so I could sit down while waiting instead of standing up (or getting my trousers wet by sitting on a wet bench). The number of times that a simple towel will come in handy will astound you.

#3 – Smartphone

Okay, so technically speaking a Smartphone isn’t a “non-photographic” item but ignoring the camera element, it has become a must these days for travel photographers. Whether it’s to check sun direction, weather forecast, maps, making notes about potential shoot locations and metadata details, to simply having access to pass the time by reading the news while waiting for sunset, a Smartphone has become an essential tool for every travel photographer.

7 Non-Photography Items Which No Travel Photographer Should Leave Home Without

#4 – Compass

For the majority of photographers, a Smartphone has replaced the trusted compass. But it’s still worth having a small one in your bag just in case your phone runs out of power or you can’t get a signal. Besides being able to bail you out when you get lost, a compass can help you determine sunrise/sunset direction where the light will move, which is essential for any travel photographer.

#5 – Gloves

Travel photography usually means early starts and late finishes as the soft light in and around sunrise and sunset is great for photography. This usually means you’ll be out and about when it’s colder than during the day and trying to work your camera dials with cold hands or even carrying a tripod is not an enjoyable experience.

During the daytime depending on the time of year, it can be pretty cold for your hands and even in the summer months it can get much colder in the evenings and early mornings. So do yourself (and your hands) a favor and keep a pair of gloves in your camera bag.

#6 – Pen and Paper

Sometimes you simply can’t beat pen and paper. It might be to take notes, to jot down ideas for shoots, to sketch a composition that you want to try and create later, or it might simply be to take the email address of the person who’s photo you have just taken so that you can email them a copy. Whatever the reason, a pen and paper is always useful to have in your camera bag.

#7 – Sunscreen and a Hat

It’s easy to forget sunscreen and a hat among all of the other things above, in addition to your photographic equipment, but they are essentials for anyone working outdoors. As a travel photographer, you will be spending most of your days out and about and it’s easy to get distracted and not notice a few hours going by. The last thing you need on a photo trip is to get sun burned.

Conclusion

Over the years, I have found that these small items have become invaluable. I will, of course, adapt this list as I go and add or remove things for certain destinations. For example, if I’m out in the wilderness I would carry a first aid kit, an emergency kit with things like a whistle, blanket, etc., a torch, and the relevant maps of the areas I’m planning to explore. But my basic list of items accompanies me on any trip even a short city break.

Over time you will build up your own set of items. But for the time being, I hope this list is useful for you.

Anything else you can think of? What non-photographic item do you always carry with you and why? Please tell us in the comments below.

Yongnuo introduces two new speedlights, including a high-end model for Nikon

27 Aug

Chinese lens and flash maker Yongnuo, known for their cheap lighting gear and lens knockoffs, has released a pair of new flash units based on existing models. The high-end YN968N is a new Nikon version of the company’s YN968EX-RT for Canon, and the mid-range TN568EX lll is an upgrade of the mark ll version.

The new Nikon-mount gun offers a guide number of 60m/197ft at ISO 100 and with the zoom set to 105mm. It features optical communication with Nikon’s and Canon’s own flash system as a slave, as well as radio connections with Yongnuo’s own 2.4GHz flash units. In radio mode it can support up to 16 channels and five groups depending on the flash units it is working with, and a built-in LED lamp in the lower side of the head serves as a modeling lamp or video light that accepts color correction filters to balance with ambient light sources.

The YN568EX lll features optical-only communication, and can also work in groups with both Canon and Nikon units. It can operate as a master in a Canon or Yongnuo set-up, and in this version recycling time from a full power burst is reduced from three to two seconds.

Both the new guns have USB ports so they can accept firmware updates as they become available.

The YN968N is on sale for $ 120, but the release date and price of the YN568EX lll have yet to be announced. For more information visit the Yongnuo website.

NASA just ordered 53 Nikon D5 DSLRs for the ISS and training purposes

27 Aug

NASA’s relationship with Nikon is as strong as ever, judging by the fact that the space agency just placed a massive order for 53 Nikon D5 DSLRs.

According to Nikon, NASA ordered the cameras as-is (no hardware modifications) and plans to use them for photography on the International Space Station, as well as astronaut training on Earth. The agency might make some changes down the line, but for now there’s no difference between the D5 cameras available to consumers and the ones being shipped to NASA.

This is the latest development in a long-running relationship between NASA and Nikon, which has provided the space agency with camera gear as far back as 1971 for the Apollo 15 space mission.

Most recently, Nikon provided NASA with 38 units of the Nikon D4 DSLR in 2013 and another 10 units of the D4 in 2016. The camera maker didn’t reveal whether NASA received any special discounts on its bulk order, but assuming NASA paid retail price, the cost could have exceeded $ 344,000 USD.

Why You Might Want to Consider Keeping a Visual Diary

27 Aug

Maintaining creativity can be difficult for artists at the best of times. Fortunately, there are ways to combat the dreaded artist’s-block. Carried around in the crook of many an artist’s arms, the visual diary has developed alongside the very beginnings of art history.

Famous artists like Leonardo da Vinci, Frida Kahlo, Vincent van Gogh and Kurt Cobain all kept detailed visual journals for their thoughts and creative progress. Cecil Beaton, famous for his portraits of Marilyn Monroe, religiously kept scrapbooks of drawings, newspaper clippings, paintings, and copious amounts of photographs. Art school curricular also relies heavily on the use of a personal visual diary to detail a student’s thoughts and processes.

Why You Might Want to Consider Keeping a Visual Diary

Materials in a visual diary aren’t limited to just pieces of paper. Here I’ve fixed a piece of plastic that I wanted to use later into my visual diary for safe keeping.

Why You Might Want to Consider Keeping a Visual Diary

Keeping track of different film I’ve used is easy with a visual diary – I simply stow the flattened box for later reference.

What is a visual diary?

As the name suggests, visual diaries are a collection of visual references compiled by an artist. Made up of notes, diagrams, collage, photography, images, and detritus, a visual diary can contain any number of materials compiled into a series of books or folders.

The purpose of a visual diary is to provide space for an artist to work within visually. By documenting your own progress and inspiration in a physical diary, you can build important skills and identify trends to further your creative skill. A visual diary also provides a cathartic space to record ideas and personal observations. You can combine private journal entries with test-prints and swatches, or you can keep a strictly photo-based body of work. You can even use separate books for separate media or projects. It doesn’t have to be pretty, as long as it works for you.

Why You Might Want to Consider Keeping a Visual Diary

Proof sheets of negatives are most useful when stored in a visual diary for easy reference.

What diary should I use?

One of the most popular formats of visual diaries is spiral-bound booklets. These booklets can be laid flat on a surface and have thick paper for sketching. Plus, you can stick a pen down the spiral joint so you’ll always have a marker at hand.

A4 and A5 booklets are generally the most popular sizes for visual journals. Larger journals are harder to transport and a very small booklet may be too little to stick cut-outs in. Lined and unlined booklets are another consideration. I personally prefer an unlined book – every sheet is like a blank canvas as it holds nothing but potential! Having said that, grid books can be useful for structured lighting diagrams and geometrical drawings.

An alternative to keeping a booklet as a visual diary, mood boards are another great way to maintain inspiration and direction. Having a mood board to look over and update frequently can be just as beneficial as having a visual diary, only it’s a little less portable. All you need is a good cork board, a few pins and a choice selection of images and notes. You can even use several mood boards, each sectioned off for different moods or projects.

Why You Might Want to Consider Keeping a Visual Diary

Keeping a mood or cork board full of artistic material can be a great source of inspiration for projects.

Why keep a visual diary?

There are many benefits to keeping a visual diary.

Organizationally speaking, having a visual diary keeps all your artistic detritus in one place. I’m definitely guilty of spreading my materials out, scribbling notes on bits of paper and losing them shortly after. Writing notes in your journal or taping pieces of paper with notes into your diary will keep them together so you can easily refer back to them later. Visual diaries are also great for unexpected flashes of inspiration – try keeping one next to your bed for those breakthroughs in the middle of the night.

Your visual diary is your own personal work space. Recording your artistic progress now will create a timeline of your personal development to refer back to later. This can help maintain your focus or realign your artistic direction. Once you get into the habit of filling in your visual diary, you will develop a pattern of creativity, training your photographic eye. Plus, if you aren’t keen on posting personal thoughts in an online blog, paper-based visual diaries are a safe space for your own creativity.

Visual journaling is good for your health too. Cutting images out and doodling in your visual diary can be a very meditative process, increasing mindfulness and reducing stress. Simple tasks like cutting and pasting photographs clear your mind of negative thoughts with repetitive motion and critical thinking.

Why You Might Want to Consider Keeping a Visual Diary

Negatives and digital proof sheets that need to be close at hand for projects are easy to find and revise in a visual diary.

Conclusion

Keeping a visual diary is a great way to boost inspiration, consolidate thoughts and even improve your mental health. As a placeholder for ideas and reference material, keeping a visual journal will quickly become an invaluable tool for developing your photography. Think of it as an artistic space, created and curated by you!

Visual diaries are not only great for storing inspirational material but for recording things like photography expenses or even your wish list.

Shutterstock’s new watermarking system foils Google’s AI

27 Aug

Following a study Google released last week showing how easily an AI could remove watermarks from stock images, stock photography website Shutterstock has introduced stronger watermarks that are more difficult to eliminate using automated software. Google notified the stock photography company about the vulnerability before publishing its research paper, and it seems the company took their warning in stride.

Google’s technology works via a computer algorithm that learns to identify the common elements in many stock images—that is, the watermark—and then remove just those elements without altering the underlying photo at all.

Google ultimately identified the consistency of watermarks as their main point of vulnerability. To counteract the vulnerability, watermarks needed inconsistencies that involved ‘random geometric perturbations.’ In other words: the marks should be warped to avoid consistency across the entire photo library. Doing this confuses the artificial intelligence, and results in watermark artifacts being left on the image after attempted removal.

Stock photography website Shutterstock has already implemented an improved watermark system based on Google’s advice. With its new system, stock photos are protected by watermarks that are applied with slight geometry changes, making it impossible for an AI like Google’s to figure out precisely which pixels belong to the watermark versus the image itself.

“The result was a watermark randomizer that our engineering team developed so that no two watermarks are the same,” says Shutterstock CTO Martin Brodbeck. “By creating a completely different watermark for each image, it makes it hard to truly identify the shape.”

Photo of the week: An epic dancer shoot in an inverted room

27 Aug

A month ago, I got in touch with my old friends over at Little Boxes Theater—a recreational performance art/photography studio in San Francisco—about shooting a fun personal project. Since I love to fabricate things in my workshop for shoots, I asked if they’d be up for collaborating on something along those lines.

Aaron Simunovich (one of the studio managers), had a lot of experience woodworking, and threw out the idea of an inverted room. Without any doubts, I said something along the lines of, “yes, let’s make this happen right now.” I immediately got to work on a detailed 3D model of what it might look like structurally, and from there, we budgeted what material we’d need in order to get this set done.

I spent the following 5 days commuting over the San Francisco bridge, gradually building the set with Aaron, and us making frequent trips to the hardware stores… and junkyards. This was all a big experiment, but I called my good friend Valentina Reneff-Olson to model, since this trippy composition just called for a flexible dancer. Combine this two-wall set with a bit of intricate posing, and you end up with a series of photos that emulate anti-gravity perfectly.

Generally, the concept was to have the dancer shooting out of what looked like a painting/mirror frame. Oh yeah, and rain. There was rain.

Technical Details

If I told you how long we actually shot for, you’d probably think I was exaggerating. The truth is, once we had everybody at the studio, we only had 2 hours to get something good. Since I had to travel back to LA for an upcoming shoot, and their studio was booked out, there was just no way to do it the following day.

Little Boxes Theater likes to store set designs in-house, but since I don’t live anywhere near San Francisco, I was not going to leave back to Los Angeles without content that was up to my expectations. Two hours to get both photo and video content? No pressure.

*Game face*

Since I wanted to test the stills and slow motion of my new GH5, I used that body with a 25mm f/1.7 lens, and did everything handheld with the 5-axis stabilization turned on. There were two lighting setups being used simultaneously:

One for stills:

  • Two 600w heads
  • Reflector

One for video:

  • LED panel
  • Reflector
  • 1K Arri fresnel

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_3099455855″,”galleryId”:”3099455855″,”isEmbeddedWidget”:true,”standalone”:false,”selectedImageIndex”:0,”startInCommentsView”:false,”isMobile”:false}) });

Since I was shooting slow motion at a higher shutter speed, I was really pushing the GH5 settings to see how it performed on this test. The power output of the strobes overpowered the constant lights, so for stills we just kept the constant lights on to help with auto-focus.

Together, we all improvised a bunch of choreography and posing for Valentina to follow, and our stylist, Virginie Suos, switched out the clothing after each video sequence in the rain. I got oddly comfortable shooting atop a scaffolding, with my head tilted 90º the whole time.

This shoot ended up being 75% stills and 25% video, so the minute-long short film that I threw together was cut only from about 6 shots only.

To that I’d say: “not too shabby Daniel, not too shabby.”

Check out the full behind the scenes video below:


Daniel DeArco is a Los Angeles-based photographer, filmmaker, and inventor who first picked up a camera in 2011 after he severely broke his neck. Since then, he’s made a name shooting creative portraits and commercial work. You can find more of his work on his website, Instagram, and YouTube.
