DSLR Add-On Brings Features Like Lytro-Style Refocusing to Any Camera

Lytro may have made a splash when the company first burst onto the scene with its 'snap now, focus later' technology, but the competition has been growing steadily ever since. In addition to companies like Pelican gunning at the light-field market, a new SLR add-on created by researchers from Saarland University in Germany promises to bring Lytro-style refusing and much more to almost any camera.

Photos of Cell Phone Towers Disguised as Fake Trees

In 1996, a palm tree was introduced to a suburb in Cape Town Africa. The tree appeared almost overnight, and it wasn't an ordinary tree: it was one of the world's first (if not the first) disguised cell phone towers. Rather than have unnatural and unattractive metal towers jutting out of the ground, companies began working to make the towers blend in with the natural environment. This fake tree concept soon spread across Cape Town, across South Africa, and finally across the world.

In response to the spread of these fake trees, photographer Dillon Marsh decided to shoot a series of photos to document the trend. The series is titled, "Invasive Species."

Canon 60D DSLR Hacked to Capture HDR Video in Real Time

HDR (high-dyanamic-range) video is no new concept. In fact, Magic Lantern has offered a way to shoot HDR footage utilizing Canon DSLRs since 2011. It's even become a feature of some mobile phones. But capturing and displaying HDR video in real-time? Well, that's another story.

Brinno Announces the World’s First HDR Time-Lapse Video Camera

When it comes to creating quality time-lapse videos, many photographers relish having a serious amount of control over their result. But if you're the kind of person who isn't into intervalometers or messing with rail systems, and you're looking for something that's more of a "set it and forget it" system, Brinno's new TLC200 Pro may fit the bill just right.

Shooting a Massive Gigapixel Panorama of the Manhattan Skyline

I focus on a relatively obscure (though rapidly becoming more popular) area of photography called gigapixel-resolution photography. I use a robotic panoramic mount to capture tens if not hundreds of images of the same location and then stitch the images together to create a single massive photograph. I've combined this technique with High Dynamic Range imaging to create HDR photographs that are anywhere from 200 megapixels to 4 gigapixels in resolution size.

Rambus’ ‘Binary Pixel’ Technology Seeks to Bring Single-Shot HDR to Smartphones

Tech company Rambus just announced "Binary Pixels," a new sensor technology that intends to bring ultra-high dynamic range to small sensors like those found in smartphones and P&S cameras. By allowing pixels to "reset" and saturate more than once, the pixel tech promises to expand the dynamic range of these sensors to "single-shot HDR" levels.

Imaging Chip from MIT Takes Smartphone Photos to the Next Level in Milliseconds

The majority of in-camera editing and enhancing, especially on the mobile front, is done via software. Software that, according to MIT's Rahul Rithe, "consume[s] substantial power, take[s] a considerable amount of time to run, and require[s] a fair amount of knowledge on the part of the user."

In order to bypass this problem, Rithe and his team of researchers at MIT have developed a new imaging chip that can act as a photographic "jack of all trades" when it comes to taking your smartphone photos to the next level.

Apple Patents Method of Generating HDR Photos from Single Exposures

High dynamic range (HDR) mode is becoming a standard feature in newer digital cameras and smartphones. By snapping multiple photographs at different exposure levels, the camera can automatically generate an image that captures a greater range of light and dark areas than a standard photograph. However, the technique does have its weaknesses. Artifacts appear if any changes occur in the scene between the different shots, which limits the scenarios in which the technique can be used.

Apple wants to overcome this issue by implementing an HDR mode that only requires a single exposure. A recently published patent shows that Apple is well on its way to doing so.

Wearable Cameras May One Day Give Us Ultra-HDR Vision

When doing certain types of welding, special helmets with dark lens shades should be used to protect the eyes from the extremely bright welding arc and sparks. The masks help filter out light, protecting your eyes, but at the same time make it hard to see the details in what you're doing. In other words, the dynamic range is too high, and wearers are unable to see both the arc and the objects they're welding.

A group of researchers in the EyeTap Personal Imaging Lab at the University of Toronto have a solution, and it involves cameras. They've created a "quantigraphic camera" that can give people enhanced vision. Instead of being tuned to one particular brightness, it attempts to make everything in front of the wearer visible by using ultra high dynamic range imaging.

How to Manually Create an HDR Photo in Photoshop

Here's a tutorial on how to do non-automated HDR for real estate photography using Photoshop CS5. The first thing you'll need is a sturdy tripod with a level. The closer you are to a leveled image, the less correction you'll have to do later.

AMP Camera Captures HDR Video in Real Time with One Lens and Three Sensors

Late last year we showed you an interesting demonstration of HDR video filmed using two Canon 5D Mark IIs. The cameras captured the exact same scene at different exposure values using a beam-splitter. Now, a new camera called AMP has been developed that captures real-time HDR video using a single lens. The trick is that there are two beam-splitters in the camera that take the light and direct it onto three different sensors, giving the system a dynamic range of 17 stops. Check out some sample clips in the video above -- they might be pretty ugly, but the technology here is pretty interesting.

HDR Photo of Endeavour Liftoff by NASA

Here's a good example of when HDR photography is useful: NASA created this image of the Space Shuttle Endeavour lifting off for the final time by combining six separate photographs.

Each image was taken at a different exposure setting, then composited to balance the brightness of the rocket engine output with the regular daylight levels at which the orbiter can be seen. The processing software digitally removes pure black or pure white pixels from one image and replaces them with the most detailed pixel option from the five other images. This technique can help visualize debris falling during a launch or support research involving intense light sources like rocket engines, plasma experiments and hypersonic vehicle engines. [#]

HDR Guru Trey Ratcliff Sues Time After Spotting Photos in Video

In mid-2010, Time Magazine showed off a demonstration of a slick tablet app they were making in collaboration with The Wonderfactory. As it became widely shared across the web, HDR photographer Trey Ratcliff of Stuck in Customs started receiving messages from fans who spotted his work in the video demo. Problem was, he had never given the magazine or the agency permission to use his work.

Combine Multiple Photos Using HDR Software for Surreal Results

Flickr user Paul Little creates surreal images he calls "HDR Mixes" by combining different photographs with the help of HDR software. While you're normally supposed to feed the program multiple versions of the same photo (which are bracketed), with HDR Mixes you use two photos of the same scene and a third that's completely unrelated.

Beautiful Chapel in Poland Captured in an HDR Time-Lapse Video

Patryk Kizny created this short HDR time-lapse film titled "The Chapel" that explores the inside of a Protestant chapel located in Zeliszów, Poland built in 1797. The HDR imagery gives the video a eerily beautiful surreal look that makes the video look like it came from a video game.

Double Rainbow All the Way in HDR

The Internet viral sensation "Double Rainbow" video was captured on January 8th, 2010. About two weeks later on the 23rd (and long before that video went viral), I saw a double rainbow myself when looking out my window. I quickly grabbed my camera (a Canon 40D at the time) with my 16-35mm lens (I wanted the widest shot possible) and ran out to shoot the rainbow.

Black and White HDR Time Lapse Shot with a Sony A700

Andrew Rees shot this beautiful black and white time lapse in Cardiff, Wales using a Sony A700 DSLR. He shot 700 pairs of photos (a total of 1400 shots) with 2.5 seconds in between pairs, and combined the resulting HDR photographs into a 12fps time lapse video.

Future Cameras May Be Equipped with Invisible Flashes

Future generations of photographers may one day look back and wonder why we often blinded each other with painfully bright flashes of light for the sake of proper exposure.

NYU researchers Dilip Krishnan and Rob Fergus are working on a dark flash that eliminates the "dazzle" effect of regular flashes in a low-light room. They've created this camera rig that combines common infrared photography techniques with an ultraviolet flash that produces a dim purple glow instead.

The team placed an infrared filter on the lens of the Fujifilm S5 Pro, which is has a modified CCD sensor that specializes in IR and UV photography. To supplement existing UV light, the team created a modified filter on an external flash to emit only UV and IR wavelengths.

HDR Video Demonstration Made with Two Canon 5D Mark IIs

You've most likely seen HDR photographs before, but how about HDR video? The above is a demonstration of HDR video by Soviet Montage, created using two Canon 5D Mark II DSLR cameras. Both cameras recorded identical scenes using a beam splitter, and captured the footage at different exposure values (over and under exposed).

Easy HDR Editing with Oloneo PhotoEngine

French company Oloneo has just released a free beta for their product, PhotoEngine. The software is a straightforward HDR creator and non-destructive editor that allows you to quickly merge HDR photos. Additionally, it has features that can adjust specific light sources in the photo, to change the white balance or the exposure. This could come in handy when shooting HDR frames that have a variety of different light sources with different temperatures.
