Hands-on with the DJI Osmo Action

16 May

DJI Osmo Action hands-on

The Osmo Action is DJI’s answer to the action cam. The 4K rugged action camera utilizes DJI’s built-in stabilization technology, offers dual screens, and like the Osmo Pocket, is simple to use.

Here is what you need to know about it.

Hardware overview

The DJI Osmo Action is built around a 1/2.3″ sensor—the same found in the Osmo Pocket—and has an F2.8 three-glass aspherical lens with a 145 degree FOV. The camera also features a de-warp function so you can maintain a wide perspective of a scene but eliminate the fish-eye effect typically found in action cameras.

The device features three buttons: power, record and quickswitch (QS). The QS button on the left-hand side lets you toggle between different video modes (video, HDR, slow) and photo without digging into the menu. Holding the QS button down will toggle between the front and back screens on the camera.

The camera is charged via a USB-C port located above the microSD slot on the camera’s left-hand side.

Build

The Osmo Action is shockproof up five feet, dustproof and waterproof down to depths of 36 feet without additional waterproof housing, though users will want to ensure that the microSD and USB charging slot is locked and the screw on front lens protector is secure before submerging. It can withstand temperatures as low as 14° Fahrenheit.

The rear touch screen features coatings to keep water and fingerprints away, and the protective lens cap has an anti-reflective coating to reduce glare and an anti-fingerprint coating to keep things free of smudges.

Photo

The Osmo Action shoots 12MP Raw or JPEG photographs in 16:9 or 4:3 ratios. A self-timer countdown feature is included, and the camera can shoot in burst mode at 3/5/7 fps. Users can select either spot metering or AE lock mode. A setting called Face-Oriented Exposure ensures that faces stay bright in the scene.

The Osmo Action also allows you to set custom white balances and shoot in full manual exposure mode with an ISO range of 100-3200 and shutter speeds up to 1/8000sec. Additionally, the camera offers WiFi or Bluetooth to connect to the DJI Mimo app. Using the camera with the app gives it added functionality: live feeds, story templates and in-app editing.

Video

The camera can shoot 4K video up to 60 fps at 100Mbps with options to shoot as low as 24 fps, HDR video at 4K 30 fps and 8x slow motion in 1080p 240fps or 4x slow motion in 1080p 120fps. Built-in dual microphones and a speaker give the Osmo Action audio recording performance that is on par with that of a high-end smartphone. Adding the 3.5mm adapter accessory will allow you to connect an external mic for higher quality audio.

Timelapse mode makes it easy to turn hours of footage into seconds with just a few taps. Timelapses are recorded at 1080p and can be set at intervals of 0.5 sec up to 30 sec and durations can be set from 5m up to infinity. Custom exposure mode can be set up to 120 seconds for shooting nighttime landscapes or starscapes.

RockSteady/EIS

A new electronic image stabilization technology called RockSteady works to create footage that is smooth and stable even when shooting at 4K/60fps. The technology has a higher image cut ratio, removing blurry shots for smoother footage and analyzing raw data from the frames to increase stability by predicting the movement of the user. It is the first handheld DJI camera to incorporate the tech.

LCD screens

The Osmo Action has a 2.25″ rear touchscreen that can be used to access all of the features of the camera. There is an additional front-facing LCD that can be activated by tapping the back screen twice or by holding the QS button down. The 1.4″ front screen doesn’t offer touch functionality. The brightness of the LCDs mean that they can be used in direct sunlight with ease.

Performance and media

The Osmo Action uses a removable battery that is charged via USB-C in approximately 88 minutes. A fully charged battery will last 116 minutes when recording at 1080/30p or 91 minutes of 4K/30p with Rock Steady enabled. The camera uses microSD cards up to a maximum size of 256GB.

Price and availability

The Osmo Action will be available on May 22 for $ 349. The in-box setup includes camera, frame kit, quick release, two adhesive mounts (one flat and one curved), screw, and a USB-C charging cable. Customers can add accessories like ND filters for shooting in bright conditions, a waterproof case for deep sea shooting, the 3.5mm adapter for attaching a mic, an extension rod for unique angles, a floating handle for shooting underwater and a charging hub that can charge three batteries at once.

What is Royalty-Free Editorial Stock Photography and Can You Earn Money From It?

16 May

The post What is Royalty-Free Editorial Stock Photography and Can You Earn Money From It? appeared first on Digital Photography School. It was authored by Kevin Landwer-Johan.

Photographs of just about anything can be sold as royalty-free editorial stock photography. How they are licensed is defined as either editorial or commercial. An image sold with an editorial license can only be used in news or general interest publications like;

  • Blogs
  • Textbooks
  • Magazines
  • Newspapers

An editorial stock photo cannot be used to directly promote anything for profit.

Photos sold by a stock agency with an editorial license are more limited in how they can be published. Commercially licensed photos can be more broadly used, but there are more restrictions on what they contain.

What’s the difference between editorial and commercial stock photo licensing?

Editorial stock photos do not require model or property releases.

You can submit photos of individuals or whole crowds for editorial licensing and no model release would be requested. If you submit any photos of people for commercial use, signed model releases are required. Whenever a person can identify themselves in a photo, a release is required if the photo is to be sold with a commercial license.

Commercial licensing prohibits the inclusion of any copyrighted elements in your photos. Any branding or products must be removed from the photos. This also goes for people and private property. These things must be accompanied by an appropriate release form. If they’re not stock agencies will not accept the images into their collections.

Editorial licensing allows visible branding, products, people and property. However, no manipulation of the content is permitted.

If you have a photo of something containing a logo or company name, you can remove it and still license the photo with a commercial license. When uploading editorial photos, you will be asked to state that you have not manipulated the photo in any way. Editorial stock photos must depict things as they really were when you took the photo.

Most stock agencies have disclaimers attached to editorial licensing of photos. The buyer is in control of how the photos will be used and must be made aware of the restrictions and their responsibilities. Stock photo agencies make it clear they are not liable for how the purchaser uses editorial photos.

Are there restrictions on the types of photos you can upload?

Most royalty-free stock agencies don’t have many restrictions. So long as you are uploading photos within the bounds of common decency, you won’t have any problems. Check with each stock agency where you wish to submit photos. They will be able to provide you with their company policy on what they want you to upload.

The law in most countries allows you to photograph anything you like from a public space. However, in doing so, you must not infringe on the rights of others or abuse their privacy. Photographing military facilities, power plants and other important infrastructure can sometimes get you into trouble. Check with local laws before you do.

Don’t just upload any old pictures. Make sure to only submit your best images. The market has become so saturated with photos that it’s increasingly difficult to make sales. Make sure your pictures stand out from the crowd.

How do you know what photos will sell?

You really don’t.

Predicting how well editorial stock may sell is very difficult.

If you have a good photo of a spectacular event or happening of international significance, it will likely sell well. If you were the only photographer to capture this amazing occurrence, then it will certainly sell better. However, these type of situations are extremely rare.

Carrying your camera with you wherever you go will increase your chances. It will also sharpen your awareness of what a good editorial image can be as you learn to focus your attention. If you leave your camera at home, it won’t happen.

Upload a variety of images and build up a large number of your photos in a stock agency website. Doing this gives you practical experience of what will and will not sell. There are many variable factors involved.

If you can build up a solid base of your own photos, you will be able to analyze which ones sell more consistently. You can then use this information to plan what you will photograph.

Once you have this information to work with you can decide on a niche or two to concentrate on. Look at which of your editorial stock photos sell the best and which of them you enjoyed making the most. This is what you will be best to focus your efforts on.

Royalty-free stock agencies boast collections of millions of photos. They contain photos already of pretty much every subject you can think of. You need to take better images than the ones they are already selling.

Browse these collections for ideas. See what others have done and come up with a new angle. If you see that there is a number of similar images that sell well, and you can produce photos of the same subject, do so. Don’t just copy. Improve on what’s already been done.

Update images you find that might be out of date. Has your city’s skyline changed recently? There may not be many new photos of it online yet.

Has there been some big news recently that you can illustrate with a stock photo? This will have to be ongoing news, or you’ll need to produce and upload your photos quickly so as not to miss the moment.

How many agencies can I upload my editorial stock photos to?

You can choose to upload exclusively to just one agency or to as many as you have time to service.

Signing an exclusive contract to supply just one agency has certain benefits. However, you are restricted to only their customers buying your photos.

Supplying to many agencies takes time. Each stock library has its own requirements and contracts, and you must understand these and follow their terms closely. If you don’t, you may find you’ll have many of your photos rejected for one reason or another.

Conclusion

Do your research and understand what’s required before you start uploading photos to sell as editorial stock. You will probably find you have a huge number of images on your hard drive you can upload.

If they’re only stuck on your computer, you’ll never make any money from them. Uploaded to a stock agency, you won’t get rich overnight, but you will earn something over time.

Taking a business-like approach to stock photography is best if you are serious about it. Treating it too casually, not paying attention to what’s working and what’s not, will not bring you success. You’ll need to stick with it and consistently upload to make a really good go of it.

Simple Methods for Creating Better Still Life Images

16 May

The post Simple Methods for Creating Better Still Life Images appeared first on Digital Photography School. It was authored by Charlie Moss.

Many find shooting still life images a real challenge when they’re just starting out because it can be hard to know where to start. But taking the time to shoot a great still life can be a rewarding and somewhat meditative pastime for photographers.

Still life photography can help you hone your photographic skills at your own pace while still creating work that can go in a portfolio or be printed for your wall. But styling tabletop images doesn’t come naturally to all photographers, so here are some simple things to think about when you’re next shooting still life.

Choose props for color and mood

Now might be a good time to go and brush up on your color knowledge, because you’re really going to need it when it comes to creating still life images! Everything, including the colors, in your still life scene, will be there because you put it there. Nothing has to make it onto your tabletop studio if you don’t want to include it in your shot.

Colors can be a way of introducing either harmony or contrast. If you were photographing something blue, for example, and you used blue and green backgrounds you’d have a very harmonious and potentially calm image. On the other hand, if you added yellows or oranges into the scene, it would create tension and result in a more dynamic overall feeling to the shot.

You can bring color to your still life images in different ways. Backgrounds, fabrics, plates, bowls, vases – all these items are props that you can start collecting to build up a color library of props. Don’t forget natural objects like flowers and foliage too; they can often really bring a shot to life.

Selecting complementary backdrops

Your backdrops will often be the most dominant colors in your scene, so pick wisely (it’s also hard to change it once you’ve started arranging your props). Pick your backdrops according to the feel you’d like to create in your final image.

Backdrops can be anything that works with the scene you’re creating. It might be a marble countertop, a beautiful old farmhouse table, or a complementary piece of fabric. Whatever helps to set the mood for your images.

As well as the color of your backdrop, think about the texture as well. A scuffed up, blackened old baking tray creates a very different feel to draped silk. Think about the way that different backdrops make you feel as you select them for your scenes and decide if that’s correct for the kind of story you’re trying to tell in your photograph.

Over time you will build up a library of different backdrops to use in your shots. Then you can create a whole variety of different styles of images just by switching out the backdrop. Keep your eye open when you’re out and about for potential backdrops to add to your library!

Thinking about texture

I love including texture in my still life photographs, and it has become a part of my style now. Scouring both high street and artists shops for interestingly textured table linens, bowls, and backgrounds for my still life images are favorite pastimes.

Along with all the other elements of a still life image, texture can really help set the mood. Are you shooting something rustic that would have its story helped by the introduction of some beautiful coarse fabric? Or maybe you’re photographing a more modern scene that would benefit from glossy backdrops and slick, shiny props?

It also adds interest and depth to your final image. If you look around the room you’re in I’m sure you’ll see a whole variety of different textures. Perhaps you have a smooth leather chair with a velvet cushion on it, placed next to a distressed wood coffee table. Our lives are a riot of different textures, and these affect our senses both visually and through touch.

Since you can’t touch the objects in a photograph, you need to tell the viewer what they’re like. Texture is the main way to visually convey what something would feel like if you reached into the photograph and touched it. With that in mind, pay attention to what the textures in your shot are telling your viewer.

Create a beginning, middle, and end

Just like a good story, a photograph needs a beginning, middle, and end. Except we usually refer to these things as foreground, middle ground, and background when it comes to visual storytelling. Creating a layered effect in your photographs helps to create depth in what is a two-dimensional object.

Try building your still life scenes intentionally. First of all, place your main object roughly where you think you’d like it to be. It helps if you put your camera on a tripod for this because you can keep the framing and focus consistent.

After you’ve placed your main object try creating some foreground interest. This could be some petals if you were photographing flowers, or perhaps the curled corner of table linen if you were shooting food. Anything that leads the eye into the shot without distracting too much from the main focal point is good. You want something that adds to the story.

Lastly, place a background element in your scene. In the shots above, I’ve added a yellow napkin which both creates interests and adds a contrasting color, but you could be more subtle. Your background itself could also be your background element if it were sufficiently interesting! It should be like a “full stop” to your composition; ending the viewer’s attention the same way that a full stop ends a sentence.

You might find it easier to play with compositional colors and shapes for the foreground and background if you use a shallow depth of field. Rendering these elements as out of focus in your scene helps to keep the viewer’s attention on the main focus of your image.

Finishing an image in post-processing

There’s no rule in creative still life photography that says the colors have to be true to life. Using different colors – or even turning your digital files black and white – can result in a change of mood and story.

Processing your still life images in Adobe Lightroom allows you to create duplicates of images and try out different color treatments while comparing them side by side. It’s great for black and white conversions too. The best thing about Adobe Lightroom is that the editing is completely non-destructive to the original file. This means you can try out everything from wild color treatments to something more conservative and always go back to the original file.

I touched on color grading your still life photographs in a previous article. It can help evoke different moods, bringing different colors to the fore. It can also help to make items really pop off the page if you use color grading in a way that emphasizes your main subject.

Color grading your shots can also help to contribute to a more coherent style in your work. You don’t always have to treat the color in your images the same way, but over time you might notice that you seem to pick up a style the more you shoot. This can help to make your work recognizable which you might find desirable.

Put it all Together

Now that you know the simple ways that you can improve your still life images it’s time for you to have a go. Get some inspiration, shoot some images, and then come back and let us see them in the comments!

Don’t be afraid to work slowly and try new things when you’re shooting still life. The objects in your scene are not going anywhere, and they won’t run out of patience as a portrait subject will! Also remember, you don’t have to show anyone the images if you’re not completely happy with them.

Adobe adds new Texture slider to Lightroom CC, Lightroom Classic and ACR

16 May
A screenshot of the new ‘Texture’ setting under the ‘Presence’ module inside Adobe Lightroom CC, Adobe Lightroom Classic CC and Adobe Camera Raw.

Adobe has announced the addition of a new Texture slider to the latest updates for Lightroom, Lightroom Classic and Adobe Camera Raw (ACR). According to Adobe, Texture is the result of user requests for a way to smooth skin without reducing image quality or spending large periods of time making adjustments.

‘Photoshop may still be needed for some workflows,’ Adobe’s Max Wendt said in a blog post about the slider, ‘but we think that Texture will be great for many of your images.’

Texture, according to Wendt, was first developed as a smoothing slider that eventually expanded to cover both smoothing and texture enhancement. Positive texture — that is, enhancement rather than smoothing — is described as something like a cross between positive Sharpening and Clarity. Negative Texture for smoothing is comparable to Noise Reduction.

Texture reduces or enhances what Adobe calls ‘mid-frequency’ areas of an image, which enables the tool to boost or reduce important details generally without amplifying noise or producing a flat, plastic appearance. Specifically, Texture is great for smoothing skin without obliterating fine details that are key to its realistic appearance.

Texture and Clarity can be used together to adjust different aspects of the image, as well; Adobe provides examples, beyond the ones we’ve included in this article, involving both portraits and landscape images. Those are ultimately just samples of different ways Texture can be utilized, however, with Wendt explaining in his post:

The best way to discover your vision is to experiment. Texture is fully non-destructive, so don’t be afraid to explore and just try things. Go too far, pull it back, go too far again. You’ll find what values work for you. It’s all about your own vision.

Users can access the new Texture slider by updating their software to the latest versions of Adobe Lightroom CC, Adobe Lightroom Classic CC and Adobe Camera Raw available in Creative Cloud.

The OnePlus 7 Pro comes with 3x hybrid tele, ultra-wide-angle and pop-up selfie cam

15 May

Chinese manufacturer OnePlus has announced its latest flagship smartphone, the OnePlus 7 Pro. The new model comes with a completely new triple camera module that features a 48MP Quad-Bayer sensor, F1.6 aperture and optical image stabilization in the primary camera. The 16MP ultra-wide-camera offers an equivalent focal length of 17mm and an F2.2 aperture.

The stabilized tele puts out 8MP image files and has an F2.2 aperture lens. It combines a longer focal length with digital zoom for an 78mm-equivalent focal length (3x). The AF-system combines PDAF and laser methods and there’s also an improved night mode.

By default the primary camera produces 12MP image files but can be set to capture at full 48MP resolution. In video mode the OnePlus is capable of recording 4K footage at 60 frames per second. In super-slow-motion mode you can shoot 1080p video at 240 fps or 720p at 480fps.

The 16-megapixel f/2.0 front selfie camera is built into a pop-up mechanism, eliminating the need for a camera notch in the display. OnePlus says the mechanism has been tested for more than 300,000 actuations.

The device is powered by Qualcomm’s high-end chipset Snapdragon 855 and UFS 3.0 storage should help increase operating speeds. The 4,000mAh battery supports fast charging. The OnePlus 7 Pro will be available from May 21st. Unfortunately it’s not quite the same bargain as its predecessors anymore. It the US is will start at $ 669 for a 6GB RAM / 128GB storage model. There also an 8GB / 256GB version for $ 699 and the top-of-the-line 12GB / 256GB model will set you back $ 749.

DJI hopes to take on GoPro with its new Osmo Action camera

15 May

DJI has taken a detour from drones and gimbals to release the Osmo Action, a robust action camera designed to compete directly with GoPro’s Hero lineup.

The compact, ruggedized action camera features the same 1/2.3-inch sensor found inside the Osmo Pocket and captures 12-megapixel Raw stills, as well as 4K HDR video. In front of the sensor is a three-element F2.8 glass lens with a 145 degree field-of-view.

As noted in our hands-on, the Osmo Action features DJI’s electronic image stabilization (EIS) technology it refers to as RockSteady, an tongue-in-cheek nod to GoPro’s HyperSmooth EIS technology. It’s worth noting though that DJI estimates an 18-22% crop factor when using RockSteady. DJI has also included a de-warp function to minimize the exaggerated perspective of the wide-angle lens.

One, er two, of the stand-out features of the Osmo Action are its dual displays. In addition to the 2.25in rear touchscreen that’s used to navigate the menu and compose shots, DJI has also added a 1.4in front-facing screen so you know what you’re getting in the shot when snapping a selfie.

Being an action camera, it shouldn’t come as any surprise the Osmo Action is designed to take a beating and keep on working; it’s dustproof, shockproof up to 1.5m (5ft) and waterproof down to 11m (36ft) as is. If more protection or underwater capabilities are required, DJI is also offering an external housing.

The device itself features three buttons: a power button, a record button and a dedicated button DJI calls the Quick Switch (QS) button. The QS button makes it easy to transition between shooting modes, flip what screen is active and change settings, even with gloves on. If the Quick Switch button doesn’t fit the bill, the camera can also be turned on and start recording with your voice thanks to integrated voice control.

On the photo front, the Osmo Action can capture 12MP Raw (DNG) or JPEG images in 16:9 or 4:3 ratios. It features an ISO sensitivity range of 100-3200 and shutter speeds between 120 seconds and 1/8000th of a second. In burst mode, the Osmo Action can capture shots at three, five or seven fps, and the self-timer mode can be set for three or ten second intervals.

When it comes to video, the Osmo Action can capture 4K/60p video at 100Mbps and 4K HDR video at up to 30 fps. For high frame rate video, the Osmo Action can capture up to 240 fps if the resolution is dropped down to 1080p.

The Osmo Action has built-in Bluetooth and Wi-Fi so it can be paired with Android and iOS devices via DJI’s Mimo mobile app. When connected, you can compose shots, change settings, capture images and instantly transfer content on the fly.

Media is stored on microSD/SDXC/SDHC cards up to 256GB. The battery, which DJI says can be fully charged via the onboard USB-C port in 88 minutes, can last 116 minutes when recording at 1080/30p or 91 minutes when recording 4K/30p with RockSteady enabled.

The DJI Osmo Action is currently available to pre-order at Adorama and B&H for $ 349. It comes with a camera frame, a flat adhesive mount, a curved adhesive mount, a quick-release base, the battery, a battery case, a locking screen and a USB-C cable. Additional accessories are also available.

The Profoto A1X is an upgraded A1 with improved battery life, recycling times and more

15 May

Profoto has announced the A1X, an updated version of its A1 speedlight that’s improved in nearly every way.

The A1X isn’t quite a successor to the A1. Instead, it sits alongside the A1 as a more powerful alternative in the event the A1 just isn’t enough for your needs. In the words of Profoto, it has ‘a little more of everything.’

Specifically, the A1X has a more powerful internal battery that gets 450 full power flashes per charge compared to the 350 of the A1. It also features a 1 second recycling time compared to the 1.2 second recycling time of the A1, 20 wireless channels instead of 8 and a new display interface, similar to the one found on Profoto’s B10 light. The A1X is also available for Sony, whereas the A1 was limited to Canon and Nikon camera systems.

Aside from the above differences, the A1X is effectively identical to the A1. It features the signature round head, AirTTL and HSS, a magnetic click-on mount for Profoto’s optional Light Shaping Tools, an LED modeling light, built-in Air Remote capabilities and firmware update functionality. The device can be used both off-camera and on-camera, features flash durations from 1/800th to 1/20,000th and can work at distances up to 300m (1,000ft).

Below is a hands-on video created and shared by Adorama:

The A1X measures in at 75mm x 108mm x 165mm (3.0in x 4.3in x 6.5in) and weighs 560g (1.23lbs) with the included battery. Included with the flash unit is a Li-Ion battery, a USB Type-A to Micro B, a power cable, a battery charger, a flash stand, a dome diffuser, a bounce card and a dedicated bag for protecting the A1X.

Chinese camera cuts through smog to record details almost 30 miles away

15 May
In this illustration (a) shows the distance between the camera and the target on a map of Shanghai, and (b) shows what the target building actually looks like. Image (c) is the view of the target through the smog of the city, while (d), (e) and (f) show earlier technologies attempting to record the target. Image (g) is the result of the researcher’s improvements

Researchers in China have created a camera that can record through the atmospheric pollutants of Shanghai to pick out objects just 60cm (2ft) high at a distance of 45 kilometers (28 miles). The ‘camera’ uses laser technology to fire light of a specific wavelength at a distant object and then uses a sensor to record the light when it returns so it can produce a picture that shows shapes with some distance information.

The project is being carried out by scientists at the University of Science and Technology of China in Shanghai, who have so far been able to record the form of a distant building with enough resolution to show the windows. The picture is technically a photograph, but not quite as we would expect to record with a normal visible light camera. The idea of the research is to produce an instrument that can ‘see’ further than is possible using visible light, and to be able to see in conditions visible light can’t get through.

At top left you can see the actual set-up of the LiDAR camera mounted inside the telescope, while the diagram top right shows what’s going on inside.

The scientists mounted a LiDAR (Light Detection And Ranging) camera inside a Cassegrain mirrored telescope and fired a near-infared (1550nm) beam from the top of a building on Chongming Island in Shanghai towards the K11 skyscraper 45km away in the centre of the city. As the scientists knew the distance and the speed of the light they were using they were able to calculate when it would return and thus isolate the image forming light from any other stray light in the scene.

An illustration showing how different methods of image extraction can be used to yield a more detailed image.

The quality of the image recorded is hardly going to serve for holiday pictures, but outlines, shapes and forms can easily be seen even when the atmosphere was too thick for visible light. The technology will be useful for seeing when we can’t see – through clouds, atmospheric haze and smog and for security surveillance.

This shows how the researchers are using distance information from the LiDAR to create depth maps of scenes that can hardly be seen with the naked eye

The researchers say they can improve the resolution and the range of their invention, and that they will be able to create 3D images in the future. Already with the range defining abilities of the LiDAR system they can incorporate depth and distance information into their images.

You can read the research paper as a PDF online.

The Ricoh GR III is a compact 24MP APS-C format camera with a 28mm equivalent F2.8 lens. The third in a series of APS-C ‘GR’ compacts from Ricoh, the GR III has been a long time coming, but updates the GR II in some highly significant ways. Several Ricoh representatives have described the GR III to us as a ‘labor of love’ – keep reading to find out whether the work of the company’s engineers has paid off.

Key specifications:

  • 24MP APS-C sensor
  • 18.3mm (28mm equivalent) F2.8 lens
  • 3-axis in-body SR stabilization system
  • On-sensor phase detection autofocus
  • Ultrasonic sensor cleaning
  • 3″ 1.04M-dot touch-sensitive LCD screen
  • Anti-aliasing filter simulation
  • Optional 21mm equivalent GW-4 wide adapter lens
  • 1080/60p video
  • USB 3.0 (Type C) enables in-camera charging

Ricoh took its time with the GR III. The original GR was announced a full six years ago, and the intervening GR II was such a minor update that Ricoh felt compelled to reduce its MSRP by $ 100 less than a month after it was introduced.

The GR III is a major update to the GR and GR II that preceded it. The resolution increase from 16-24MP was expected (and overdue) but the addition of sensor stabilization, a touch-sensitive screen, and the removal of the built-in flash make the GR III a very different photographic tool, albeit one that should feel instantly familiar to GR / II fans.

The GR III is available now for $ 899: $ 100 more than the introductory price of the GR II in 2015 (and $ 200 more after the GR II’s rapid MSRP reduction three weeks after it launched).

KONO! launches new 35mm Original Mirage film stock and Original Sixpack

15 May

European analog photography company KONO! has announced a new film stock called Original Mirage. This 35mm C-41 200 ISO pre-exposed color negative film offers ‘two awesome colors at once,’ according to KONO!, which has added the product to its ‘Original’ line.

Images captured on the Original Mirage film experience a distinct color shift from warm to cool; when the environment is bright, KONO! likens the color shift to ‘a warm, late summer day’ that, in the same photo, transitions toward a late day likeness in which the ‘colors get more prominent and richer.’ Below is a collection of sample images captured on the new Original Mirage film:

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_9597090346″,”galleryId”:”9597090346″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

In addition to the new Original Mirage product, KONO! now offers an Original film bundle containing six film products in the series: Original Sunstroke, Original Moonstruck, Original Monsoon, Original Candy, and Original Galaxy. The new Original Mirage film is included in the six-pack bundle for free.

A roll of the 24-exposure Original Mirage costs $ 14 USD; the KONO! Original Sixpack is available now for $ 67 USD.
