A lot has changed over the last 50 years in photography, and if you need evidence of that, check out this rather fascinating short film about photographer David Buett. At the time, he was working for Contact Press Images doing documentary photography and also wearing some very era-appropriate robes when hanging around the house. In the film, Buett takes an assignment to document some cowboys moving a herd of cattle in the American southwest. It’s full of absolutely fascinating little bits of information. We get to hear him talk about putting some of the costs for the trip on a credit card in order to defer the cost. We get to see the process of selecting images and then looking at them once they have been published. We also get to see some of the images, which rounds the whole thing out nicely.

Not everyone is on-board with the semi-recent rise in software subscription plans, and Corel is emphasizing that fact with the release of its new PaintShop Pro X9 and X9 Ultimate photo editing software. There is a handful of new features in PaintShop Pro X9, all of which will likely appeal to specific sets of users. The new Project Templates make it easier to create design projects such as greeting cards and collages using photos and text. A new Screenshot feature is meant for capturing and aotating things that appear on the computer screen. The new Interactive Gradient Fill is designed to give more control when doing local adjustments on an image. And the software now supports Windows Real Time Stylus in case you’re working on a device such as the Surface or SurfaceBook. (The software is compatible only with the Microsoft operating system, not with Apple’s OS.) There’s als

The new Sony Wireless Radio flash trigger system hasn’t started shipping just yet—it’s slated for early September—but Sony is getting its flagship full-frame camera, the A7R II ready with a new firmware update. V3.30 of the Sony firmware brings full compatibility with the new flash trigger system, which I got to use briefly in concert with the new Sony lenses out in San Diego. In addition to the trigger compatibility, the update also includes overall stability and “improves stability in picture shooting mode (optimizing temperature control, effect is different according to temperature).” Even if you haven’t been having issues or you won’t be using the new flash triggers, it’s good to keep your camera up to date with the latest updates so you don’t get too far behind.

Gear Acquisition Sydrome is something that gets talked about a lot online as a way to describe the overwhelming compulsion many photo enthusiasts feel to constantly buy camera gear. For Dilish Parekh, the urge isn't about the latest and greatest, but rather building a huge archive of classic cameras he keeps as a collection. His hobby started decades ago, and since then he has put together an arsenal of more than 4,500 cameras—and the collection keeps growing. Many of his cameras are cheap and obscure, but from the looks of the video, there are also some true gems to be found in there, including the Leica 250, which can fetch tens of thousands of dollars on its own depending on condition and type.

Pro-grade DSLRs like the Nikon D5 or the Canon 1D X Mark II (or standard DSLRs with grips attached) require a big bag. The problem is that the bags typically don’t get smaller when the gear is removed, so you have that Ninja Turtle look even when you’re actively shooting. The Think Tank Shape Shifter bags, however, compress down to just 3-inches deep when there’s no gear inside. Then, the bag can re-expand to carry those big camera bodies home. There are three different models of the new Shape Shifter V2.0, across two different sizes. The Shape Shifter 15 holds a 15-inch laptop, while the Shape Shifter 17 holds a 17-inch laptop. There’s also a “Naked” version of the Shape Shifter 17, which uses Skin Pouches or Lens Changers instead of traditional padding to make it more customizable.

[embedded content] Lost in Light from Sriram Murali on Vimeo. If you tried to capture the recent meteor shower, you may have found things more difficult than expected. One common culprit for ruining epic night sky photography is light pollution from cities. Heavily populated areas throw so much light into the sky that it can almost totally wipe out the ability to capture celestial bodies effectively with long exposures. this clever video from Sriram Murali shows the effects of light pollution in a very nice time-lapse format. Obviously, the areas with less light pollution provide more spectacular views of space. So, next time you’re thinking about getting out into the dark for some impressive views of space, make sure you take the time to get far, far away from the bright lights of the big (or even small) city. If you want to find dark sky near where you live, there are several apps a

Color accuracy is often one of the most neglected aspects of photography, and it can be costly once you get into things like printing. Datacolor has released a new bundle including three of its popular calibration products in one case for a single lower price. The Spyder5 Capture Pro bundle includes the SpyderCheckr and SpyderCube tools meant to be used during a shoot. Both offer reference points that can later be used when editing to get consistent and accurate color. The Spyder5Elite is a display calibration system that helps monitors display accurate colors that will match printed photos. The SpyderLenscal is actually meant to calibrate lenses with specific cameras using inteal micro-adjustments to help ensure sharp images.

Last we checked in on Eye-Fi the company was taking some serious flack for aouncing that its cards sold before 2015 would no longer be supported and lose functionality because of changes to the software. Now, the company has released a new Mac utility called Eye-Fi X2 Utility to keep OS X users in operation, at least for a while. According to the aouncement, the software will transfer images to a computer using “an Infrastructure or Direct network coection.” So, it won’t have the full capabilities users are used to, but the cards will still be viable for some usages. There are more caveats, as well. Right now, the company says it’s considering a Windows version but can’t commit to it. The release is also said to be a one-time release, so no updates are plaed for the future. It's good to see that the old cards won’t be totally obsolete for all users, but many photographers will still be totally out of luck. It will be interesting to see how Eye-Fi users react to th

As you might expect from a general interest news network, there’s not a ton of nerdy information available in the video, but historically a company called Camera Corps from the U.K. has been involved in a lot of these initiatives. I actually got to use one of the robotic cameras back at Photokina 2012. Cruising around the Getty site, there are some pretty impressive underwater shots of the swimmers with a fisheye-style lens, including this one from iconic sports photographer, Al Bello. I haven’t seen as much 360 VR coverage from the Games as I would expect so far, but then we saw a whole bunch of 3D coverage from the 2012 games and we all know how that worked out, so maybe it’s good that the tech isn’t trying for too much too fast.

[embedded content] Getting started with off-camera lighting can be a bit overwhelming. You have triggers, modifiers, models, reflectors, power settings, and a million other things to think about. The best way to start, however, is by keeping it simple. This well-done video tutorial (with help from Elinchrom, who didn’t pay for this post in any way shape or form) shows the process of creating a nice one-light portrait from start to finish. Here, you’ll find the editing process. This is a great weekend project because it’s something that’s easy to set up, doesn’t take a lot of gear or space, and allows for tons of tweaking. The final product in this case is actually a little too "dramatic" for my taste in this case, but that's one of the great things about a technique like this, you can tweak it endlessly until you get what you want.

During a recent studio visit with iconic group portrait photographer Neal Slavin showed off one of his favorite old cameras, the Linhof Master Technika, which he says he has owned since the early '80s.

"It's a real workhorse. It has traveled with me pretty much around the world. Wherever I went, I would always use this as my camera of choice," Slavin says. "We had great times together, it and I, and I've made some great pictures with it, I think. It's a wonderful machine."

This old 4x5 camera has an omni-directional film back that allows for swing and tilt movements for interesting focus effects. Compared to a full-frame DSLR, a 4x5 camera has a crop-factor of roughly 0.29x, which means a 150mm lens that is on Slavin's camera will have roughly the same field of view of a 50mm lens on a full-frame body. You can still buy a new Linhof Master Technika “Classic” via custom order for around $10,000, while older used models can be had for $1,500 and up on the secondary market—but don't expect Slavin to give up his anytime in the near future. He says this is one camera he won't be parting ways with.

With most wide-angle lenses, distortion is a way of life. Warped edges and a bulging center are often byproducts of a wide field of view, but Venus Optics created its new Laowa 12mm f/2.8 lens with a promise of “close-to-zero” distortion. This full-frame (35mm format) lens will be available in mounts for a variety of popular DSLRs and mirrorless interchangeable-lens compact (ILC) camera systems.

The 12mm lens covers a 122-degree angle of view, which Venus claims makes it the widest rectilinear lens with an f/2.8 maximum aperture. The optical formula includes 16 elements in 10 groups, with three Extra-Low Dispersion elements and two aspherical elements. Despite all that glass, it weighs in at 1.34 pounds.

The lens is currently in Kickstarter mode and you can currently (as of the time of this post) get one for a pre-order price of $899. Once the early-bird deals are over, the price moves up to the retail price of $949. It’s available for Canon EF, Nikon AF, Pentax K, and Sony A and E mounts.

There’s actually a pretty great selection of technical information available on the Kickstarter page, so if you’re curious about how this thing actually works, it’s worth checking out. We're looking forward to getting a production model in to the Popular Photography Test Lab to see how well it lives up to its claims.

Setting up one of those “hands-in-bowls” time-lapse recipe videos that are oh-so-popular on the inteet right now can be trickier than it looks because of the camera angle. The Povie is a lanyard-style smartphone camera mount, however, that looks to remedy the problem of how to hold your camera when you’re already using your hands.

The actual mount includes a hinge, so the phone can be held at whatever angle is ideal for getting the best point of view. It might not be ideal for walking around since the footage won’t be that stable and, well, you’ll look kind of ridiculous, but if you make how-to videos that show your hands, this could actually be really great. Of course, you could always wrap a Gorilla Pod around your neck, but that’s not quite as elegant.

On a personal note, my giant beard probably precludes me entirely from using this. Other people with giant beards, take heed.

Say what you will about mirrorless cameras, but when it comes to professional photography in challenging situations, most pros still use high-end DSLRs to get the job done. Nikon’s latest, the D5 ($6,497, street, body only), builds on the capabilities of its predecessor, the D4s, to reach new heights for Nikon in terms of speed, noise control, autofocus, and video capture.

The pixel count rises to 20.8MP from 16.2MP. Standard sensitivity now spans ISO 100–102,400 and can be expanded to cover ISO 50–3,276,800, though in its specs Nikon rounds off the top end to 3,280,000. The burst speed steps up to 12 frames per second with a massive buffer capacity of up to 200 JPEGs, 102 14-bit RAW, or 92 TIFF files. Lock the mirror up and you’ll get 14 fps.

The new 153-point AF system works with the 180,000-pixel metering system for 3D subject tracking. The LCD screen steps up to 2,359,000-dot resolution with touch controls during playback, but not while shooting. Video has been bumped up to include 4K capture at up to 30 fps. While the D4s had one CompactFlash and one XQD slot for memory cards, you’ll have to choose a model with either two CF or two XQD slots. (Our test unit used XQD.)

Given all of these improvements, we were eager to see how the D5 would stand up in the Popular Photography Test Lab and in the field.

In the Test Lab

Our overall image quality rating balances resolving power, noise, and color accuracy to assess the image capture of a camera. The Nikon D5 eaed an Excellent rating in image quality from its lowest sensitivity of ISO 50 all the way through ISO 12,800. In contrast, the D4s managed to hold its Excellent rating only up to ISO 800. The difference here comes down to the D5’s extra 4.6 megapixels, which let it maintain Excellent-level resolution even at ISO 25,600.

At ISO 50, the D5 captured 2625 lines per picture height. That’s not even a hundred lines more than the D4s’s 2550. But, while the D4s fell below our cutoff of 2500 for an Excellent rating above ISO 800, the D5 could nab 2510 lines even at ISO 25,600. As sensitivity rose further, resolution began to drop rapidly: to 2410 lines at ISO 51,200; 2160 at ISO 204,800; and 1525 at ISO 819,200.

At the camera’s top sensitivity of ISO 3,276,800 everything becomes blanketed in a sea of snowy noise under which about only 990 lines per picture height could be seen. It’s hard to imagine when someone might make practical use of the images the D5 makes at that sensitivity. But with the benefits to the images at lower ISOs, we won’t complain too much.

In our color accuracy test, the D5 easily gaered an Excellent rating with an average Delta E of 5.3. That essentially matches what we saw in the D4s, which scored 5.4 in this test in which lower scores are better.

While we usually use the software that comes with the camera to convert RAW files to uncompressed TIFFs for evaluation, with the D5 we instead used Adobe Camera Raw for conversion. Back when we tested the D4s, Nikon’s View NX 2 software varied the amount of default noise reduction applied according to ISO used. The new version, View NX-I, appears to apply the same level of noise reduction to all images. So, as we do with some other cameras, we applied 0-, 25-, 50-, 75-, and 90-percent luminance noise reduction with ACR and then looked at how noise and resolution were affected, selecting the best balance of both for the final test results. In this case, we applied 25 percent from ISO 50 through 1600, 50 percent at ISO 3200, and then 75 percent from ISO 6400 through 3,276,800. At the highest sensitivity settings, even this much noise reduction ended up a blurry mess, but the settings used followed closely what Nikon had chosen to do with its default settings on the D4s’s images.

At these settings, the D5 achieved a noise rating of Low or better all the way up to ISO 12,800 with an Extremely Low rating from ISO 50 through 400. It reached an Unacceptable rating for noise at ISO 51,200 and higher. The D4s also had a Low or better rating through ISO 12,800, though it didn’t reach Unacceptable until ISO 102,400.

Looking across DSLR brands, that’s very similar to what we saw in testing Canon’s EOS 5D Mark III, which remains one of the best performing cameras in terms of noise. Canon’s 1D X got a Low or better rating only up to ISO 3200 and reached Unacceptable at ISO 12,800 and above. However, we have yet to test the 1D X Mark II (it’s slated for our next issue) and we wouldn’t be surprised if it shows a marked improvement over its predecessor.

Normally, we’d start talking about autofocus here. But, we’ve decided to shelve that lab test, originally designed for film SLRs in the late 1980s. All the DSLRs we’ve tested in recent years have very fast AF when measuring how quickly the camera focuses and captures an image—even in very dim conditions they lock on and capture in less than a second. Going forward, we’ll speak about the versatility of AF systems and provide observations from our field testing.

In the Field

Designed to be used every day in extreme conditions and for long stretches of time, the D5 feels very comfortable in the hand, despite its size and heft. The grip is expertly sculpted and the control system versatile and well thought out.

A small joystick on the camera back lets you reposition your AF point at a whim, while dedicated buttons for ISO, bracketing, drive mode, image quality, metering, and shooting mode make changing any of the most commonly changed settings simple. Dual command wheels make manual shooting easier, and you can even use the extra command wheel for direct access to exposure compensation when shooting in aperture- or shutter-priority mode. Meanwhile, a bevy of options to customize buttons and dials let you tailor the D5’s controls to your preferences.

The autofocus system lets you select from 55 of the camera’s 153 total focusing points, 99 of which are cross-type. All the AF points are sensitive to at least f/5.6, while the center 15 are sensitive to f/8. This can be a real boon if you like to use long lenses with teleconverters, which cut the amount of light coming through to the sensor. The system lets you group focus points or set the camera to use 25 or 75 points during continuous AF rather than the full 153. In our tests it did a wonderful job of tracking subjects, even through challenging, erratic movements.

Burst shooters should be pleased with 12 fps continuous drive with full autofocus and exposure metering between shots. Plus, if you want to get even faster capture and can deal with locked AF and AE, you can lock the mirror up and shoot at 14 fps.

At 12 fps, you can capture up to 200 JPEGs or 102 RAW frames before the buffer fills. That’s well ahead of the buffer capacity of the original Canon new 1D X, which also shot at 12 fps or 14 fps with the mirror up. However, the 1D X II touts a 14 fps continuous drive (16 fps with the mirror up) and shoots JPEGs until the memory card fills or up to 170 RAW files before the buffer fills when using a CFast 2.0 card (the rival to the XQD format).

Video shooters should be pleased with the footage from the D5. It’s as good as we’ve seen from any DSLR in either 4K or Full HD mode. There’s a slight hint of rolling shutter (AKA jello effect), but it’s quite minimal and, absent a full-frame CMOS sensor with a sensor-based global shutter option (something that doesn’t exist in any consumer-grade cameras yet), this is about as good as one can expect. Canon’s 1D X II can capture 4K at up to 60 fps, while the D5 tops out at 30 fps, but that’s likely not going to push someone to switch systems. The Canon does include its Dual Pixel CMOS AF, though, which can allow for a better continuous AF experience if it ends up behaving the way we’ve seen that system do recently with the 80D.

We don’t usually talk much about batteries, but the D5 uses the same one as its predecessor and can get up to 3,780 shots per charge. So, if you currently own a D4s, your charger and any extra batteries you have will work with the D5.

The Bottom Line

When it comes to really high-end DSLRs, photographers tend to be well entrenched in a particular system. So, we have to ask if any particular camera is enough to make someone switch or compel you to step up from the body you currently use.

Nikon D4s shooters will have to weigh a few things: One, is the addition of 4K capture something you think you absolutely need? Also, will capturing an extra frame per second and the promise of a deeper buffer make a huge difference to your shooting? If you already have a solid experience with the D4s’s AF system, then the D5’s improvements might not make a huge difference, though it is rated to function all the way down to the darkness of EV –4 while the D4s was rated down to EV –3. Again, it’ll depend on what you shoot.

Canon shooters seem like they’ll have a worthy follow up to the 1D X, and we’ll put that to the test next issue. If the 1D X II lives up to the hype, then it doesn’t seem like Canonites would have reason to flock to the D5.

But Nikon photographers who are looking to step up to this level of camera for the first time should hop to it. The D5 is a wonderful DSLR and, as long as you don’t need the mega-resolution of the D810, you will likely be overjoyed with all you can do with the D5.

Looks like Samyang (or Rokinon, depending on where you live) is keeping its streak of summer lens aouncements alive with the new 35mm f/1.2 ED AS UMC CS prime lens for crop sensor cameras. There’s also a cinema version with called the 35mm T1.3 ED AS UMC CS.

The key selling point for the new manual focus lens is the fast f/1.2 aperture, which uses a total of nine blades. There are nine elements in seven groups, including two aspherical elements. It uses the latest Ultra-Multi-Coating as well, to protect the exposed elements and reduce flare and ghosting.

The lens focuses down to 1.24 feet and weighs just under a pound, varying a little bit depending on which mount you choose.

The Samyang 35mm f/1.2 ED AS UMC CS will be available in Fujifilm X, Sony E, and Canon M mounts for APS-C, as well as Micro Four Thirds. In the USA, it will presumably wear the Rokinon badge, and we’ll update this post when official pricing and availability are aounced.

It's not often that we post sample images from a camera or lens that we didn't actually shoot, but there has been a ton of talk about the new super-fast Nikon AF-S NIKKOR 105mm f/1.4E ED Lens and what kind of bokeh it's capable of. Now, Nikon has posted some official smaples and, as you might expect, the blur is in full effect.

There are seven images in total, a few of which I'm posting here. They're not super-high-res and it's unclear how much processing they have received (though, it doesn't look like much), but that bokeh does look very clean and pleasing.

We're looking forward to getting our hands on this as soon as possible, but this will have to do for now.

Researchers have been doing some very cool stuff with imaging algorithms lately, including trying to automatically colorize black-and-white photos and even remove reflections from images after the fact. The latest bit of mad science comes from Princeton University researchers and tries to make portraits shot with a wide-angle lens (like the ones on smartphones) look like they were shot with a more portrait-oriented, short telephoto lens.

The technology maps a model of the face and then uses what’s basically a map of the lens characteristics to make adjustments that result in a photo that looks like it was shot from a different distance, using lens with a different focal length. The results aren’t perfect yet, of course, and there’s no real public demo that I could find beyond the pre-made examples, but I could see how this kind of automatic feature might be very appealing to some people, especially those who take a lot of smartphone selfies.

In its early days, a lot of people were eager to compare 360-degree panoramas and other VR-like photo applications to the ill-fated 3D fad circa 2008. But, 360 photography has already gained far more traction in the industry and it seems like it’s just a matter of time before it ends up natively in smartphone cameras. Until that time comes, cameras like the Insta360 Nano, which plugs directly into the iPhone to capture 360 panoramas, will likely pop up all over.

The $199 camera is available on Amazon and has a built-in Lightning Port adapter so it plugs directly into the bottom of the iPhone. The Insta360 Nano has two imaging modules and lenses that work simultaneously to give a totally spherical capture.

It can shoot video at 3K resolution from each module, which can be combined into VR footage. From the examples, the image quality isn’t exactly as mind-exploding as a high-end VR camera, but it’s fairly affordable and lets you skip the step of having to upload footage after it’s shot or to pair your phone to the camera via wireless, which isn’t always reliable.

It’s no secret that Adobe would like Photoshop and Lightroom to be pretty much everywhere, and now the company is putting a version of Lightroom onto Apple TVs. As you already know, the Apple TV is a device made for consuming media, so if the headline got you excited about editing Raw files on your TV, sorry to dash your hopes. What it is meant to do, however, is give a high-end, integrated way to show Lightroom photos on a TV.

All of the photos viewed on the Apple TV need to be synced through the Creative Cloud, but they will represent the latest versions with current edits, so no bland Raw files will be on display. The app is free from the App store and will work on fourth-generation Apple TVs and presumably future models when they’re released.

The images can be browsed individually or as collections, and you have the ability to zoom in and see high-res images.

While this isn’t exactly a mind-blowing development in the Lightroom world, I can see this being very useful for photographers who want to show work on a display in a studio or at an event or something like that.

Super-fast lenses are as popular as they have ever been right now, and Nikon will surely be making some bokeh addicts happy with its new AF-S Nikkor 105mm f/1.4 ED portrait lens.

According to the press material, this is the first 105mm lens to hit the f/1.4 aperture mark, which means its longer focal length should give it an even more pronounced shallow-focus effect than the popular 85mm f/1.4 portrait lens.

The press release for the new lens puts a clear emphasis on the look of the lens, using words like “luxurious” and even “sultry”—clearly meant to describe the look of the bokeh, but Nikon has put its most recent tech into the lens as well. It uses the electromagnetic aperture control tech to help accommodate high-speed shooting in cameras like the new D500 or the D5. It uses fluorine coatings to help prevent the lens from attracting dust and finger prints. It also uses the most current version of the Nano Crystal Coat to combat flare and ghosting.

On the inside, the lens has 14 elements in nine groups, including three extra-low dispersion elements and a nine-blade aperture.

As you might expect after having read that spec list, the AF-S NIKKOR 105mm f/1.4E ED Lens will also command a rather luxurious price tag of $2,199. That makes it considerably more expensive than the other Gold Ring primes that Nikon offers, but there’s really no other lens like this on the market, so that comes at a premium.

I am very curious to see how this lens performs, especially when shooting wide open. There has been a resurgence in interest in the 135mm f/2 and even 200mm f/2 lenses lately for their extreme bokeh and relative abundance of image compression and this new lens seems like it should do both rather well.

We’ll bring you impressions and a full review as soon as we have a retail unit in hand.

While some of us demand more and more control out of our smartphone photo apps, there’s a larger contingent of casual shooters who are hoping that auto mode eventually gets smart enough to handle any situation that might come up. The new Microsoft Pix app is aimed clearly at that second category, offering automatic modes to help people take better pictures through algorithms.

Microsoft Pix automatically analyzes the scene being captured and prioritizes certain elements in order to anticipate the most important elements. Faces, for instance, hold lots of importance, so the app will automatically try to get them exposed and color-balanced correctly. it also recognizes when a scene has too much contrast or strong backlight. Once the photo is taken, it gets automatically enhanced to further fix tricky shooting situations.

In terms of composition, the app actually takes 10 shots at a time in a burst when the shutter is pressed, so it can keep the photos with the “best” composition. It can also combine that burst of photos into a Live Photo, which adds motion to the short video and can even restrict the movement to a part of the frame like a cinemagraph.

This certainly isn’t the first effort to automatically improve people’s ability to take “good” photos, and it definitely won’t be the last. Google has been in the auto-enhance game for a while and several of these features existed in some form before in Microsoft’s now-defunct Lumia camera tech. Microsoft has also baked in the Hyperlapse tech, which was a hit for its ability to produce smoothed-out time-lapse videos.

The Microsoft Pix app is currently available only for iOS, so no Android compatibility just yet.

Advancing Your Photography has been doing some excellent work lately with their video series about Ansel Adams. The most recent video actually goes inside of Ansel’s darkroom and gives a look at the place where he made some of his truly great work.

It’s full of fascinating little tidbits, including the fact that both his enlarger and his easel were on railroad tracks to move forward and backward. We also get to see some of his dodging and buing tools.

Oh, and did you know he would microwave his test strips to make sure he was checking against dry prints? Fascinating.

The itch for me to get back in the darkroom has been extremely strong lately and this video series is certainly making that much stronger. The man was a master and seeing his work and workspaces is a true inspiration.

The idea of capturing images of colorful reefs and shadowy shipwrecks is alluring to any scuba diver. While waterproof compact cameras may take you part way to bringing back interesting photos from your dive adventures, you’ll get much better control over your images with a more substantial camera encased in an underwater housing.

But choosing the right underwater housing can—and should—be an involved and carefully-considered process. There are plenty of options and you want to be sure you’re getting a rig that best suits your needs (and your budget). Here are the key aspects to consider when shopping for your new housing.

Depth Rating

One of the most critical specifications for an underwater housing is its depth rating--the maximum depth (and pressure) at which the housing is designed to function. At sea level, air pressure is 14.7 psi (pounds per square inch) but increases by 14.7 psi for each additional 33 feet (or atmosphere) below the surface. Exceed the recommended depth rating and controls may not function, the housing may leak or, worst case scenario, implode.

Choose a housing that meets or, better yet, exceeds how deep you plan to dive. PADI --Professional Association of Diving Instructors--the largest scuba certifying agency in the world, sets the depth limit for certified begier divers at 12 metres/40 feet; the maximum depth for advanced open water divers/recreational scuba diving is 40 meters/130 feet. It’s no surprise, then, that camera manufacturers’ housings, such as those from Olympus and Canon, are generally capped at 130-150 feet. Third party DSLR/mirrorless housings are often rated to 200-300 feet.

Plastic or Aluminum?

While a few housings are manufactured of both polycarbonate (high strength plastic) and aluminum, most are constructed of one material or the other. Plastic housings are more affordable than their aluminum counterparts—often by a thousand dollars or more—but require some compromises. They’re usually somewhat bulkier and less durable over the long run. The latter shouldn’t affect those who dive on vacation several times a year but if you’re hard core and spend your weekends exploring reefs and shipwrecks, you may want to invest in an aluminum housing.

Most aluminum housings start at around $2,000 (without a port) and go up from there. But they’re more rugged than plastic models and can withstand heavy use. Additionally, aluminum housings are more finely machined, providing smoother operation of controls.

However, since housings are generally camera specific, your options may be limited to one material or the other depending on your camera model. Most housings for fixed lens or advanced compact cameras are plastic, while DSLR and mirrorless camera housings generally offer more of a choice.

Ease of Operation

Key to ease of operation is access to controls. Check the housing (or the manual, if available) to ensure that there are sufficient buttons/levers/dials/knobs to focus and adjust settings such as ISO, aperture, shutter speed, EV, etc.

Additionally, look at the control layout to see whether you can operate the camera while maintaining a sturdy grip on the housing. And, if you’re a cold water diver, be sure the controls are large enough to manipulate while wearing mitts or gloves.

Look at the tray and handles, which may be optional but configurable, to gauge the comfort of holding the camera. If you plan to add strobes, video lights and other accessories such as an exteal monitor, be sure the housing offers sufficient and appropriate coectors.

Lens Ports

Think of a lens port as the “window” on the front of the housing that the lens shoots through. Some waterproof cases—usually those designed for compact cameras—are equipped with a permanently attached port. You may be able to purchase an optional “wet lens” that mounts to the outside of the port to add wide angle and macro capabilities.

For DSLR/mirrorless camera housings, you need to purchase one or more ports to match the lens(es) you’ll be using so be sure to build that expense into your budget. Wide-angle lenses are the mainstay of most underwater photographers and require a dome (curved) port to maintain the lens’ field-of-view and avoid vignetting. Also, you may need a port extension—a small add-on that fits between the port and the housing—to adjust the lens-to-port distance for different optics. While you can take close up images with wide-angle lenses, for the best macro shots you’ll need a macro lens and flat port. In addition to Backscatter.com, a retailer that specializes in underwater photo gear, manufacturer sites (see resources sidebar) offer guidance for configuring the perfect lens/port combination, as well as what focusing gear(s) you’ll need.

Ports are available in either glass or acrylic. The former is heavier and more expensive but offers better resistance against scratches and may provide improved optical performance (sharpness, color reproduction, etc.). Acrylic/plastic ports are somewhat lighter, cost less but are prone to scratches. Because of their curvature, dome ports are particularly susceptible to scratching but minor scratches on the outside of the port are generally not noticeable because the water essentially fills them in. Major scratches can be polished out with specially designed “sandpaper” such as the Micro Mesh dome port restoring kit, which can be purchased online or at retailers that support underwater photography.

Lighting and Accessories

Given the density of water (800 times that of air) and the absorption of light waves, strobes or constant video lighting are needed to provide bright, colorful underwater photos. As sunlight enters the water, each wavelength is absorbed at varying depths. Red disappears at about 15-20 feet, followed by orange and yellow, leaving you with heavy blue or green casts. The only way to bring back color is to add artificial lighting.

Regardless of the type of lighting (strobe or continuous), power needs to be adjustable to suit the shooting conditions. For macro shots, a single, low power exteal strobe will usually suffice given the short strobe-to-subject distance.

Wide-angle shots, however, require broader and more powerful coverage. For the best results, consider high power, dual strobes, each positioned on either side of the camera.

To attach the strobe(s), you’ll need adjustable arms to position the strobes for the best coverage and to avoid backscatter—white speckles caused by light bouncing off tiny particulates in the water and then reflecting back into the lens.

If you’re shooting video or want better visibility than the camera’s viewfinder or in Live View on the camera’s LCD, consider an exteal waterproof monitor. Be sure it’s waterproof to the same or better depth as your housing. If your camera requires an exteal recorder to capture 4K video, at least one company (Nauticam.com) offers a housing for the Atomos Shogun.

The Olympics in Rio are happening soon as you might already know, and for Getty Images Sport, the Games are very serious business. This moing, the agency posted a picture of some of the Canon gear it will be issuing to its photographers to capture the 1.5 million images or so that will come from the competition.

Even if you’re not from the Canon camp, all those EOS 1D X Mark II bodies and big white zoom lenses are worth drooling over. I’m not going to do the hard math because this is obviously a very expensive pile of gear, but consider that each EOS 1D X Mark II is $5,999 retail, and the popular EF 200-400mm F/4L IS USM Extender retails for $11,000. Then we get into the really long lenses.

If you’re curious about the Getty Images Sport strategy for capturing the Olympics, check out our full interview with VP, Ken Mainardis.

Putting together a collection of classic camera gear can be a ton of work, achieved through a lifetime of dedication and ceaseless chasing. Or, you could just plunk down a cool $1 Million (plus $1,000 for shipping) for this collection of “thousands” of classic cinema lenses.

The auction comes from Calkovsky Cinema Worldwide, a very reputable seller in the cinema world. The collection has some very recognizable names like Zeiss, Canon, Schneider, and other companies that may be much more familiar to cinema shooters than still photographers.

According to the listing, all of the lenses are in working order and are well-maintained.

For an auction like this, I wish the pictures of the actual lenses were, well, better. It’s hard to get a real grasp on how huge this collection really is and what’s in there. Still, how awesome would it be to roll into a room like that with a high-end mirrorless camera and a sack full of adapters to give all these a try?

Here's the official auction page.
