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

brinno2

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

gigapixmanhattan

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

binarypix

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. Read more…

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

mitchip1

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. Read more…

Apple Patents Method of Generating HDR Photos from Single Exposures

applehdrpatent

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.

Shooting a Rocky Beach in HDR with Trey Ratcliff

Trey Ratcliff is the well-known and well-loved HDR photographer behind the travel photography blog Stuck in Customs, and in this behind-the-scenes video he talks you though his gear and how he sets up a few shots of this rocky beach in the Virgin Islands. The video offers some great insight into Trey’s thought process as he composes the resulting HDR images, one of which you can see in higher resolution (including some 100% crops) here.

Time-Lapse Journey into an Abandoned Asylum Created with 35,000 Photos

Washington Times video producer Drew Geraci created this amazing time-lapse video of an asylum that was abandoned decades ago.

Opened in the early 1920s, the Asylum closed down and was abandoned decades ago. Rooms remain untouched – left as they were when the last of the employees departed. These buildings stand as a testament to the horrors and miss treatment that patients had to endure during the time of its operation.

Our 7 month journey into the Asylum led us on many adventures; from dodging security vehicles, ghostly figures and even a meth head. This is no place for the faint of heart. Asbestos blanketed every room we entered like new winter snow, so shooting was sometimes difficult.

They used a combination of traditional HDR, tone-mapping, and time-lapse techniques. Every single frame was a still photo, and they snapped 35,000 of them with two Canon 5D Mark II DSLRs over 7 months to complete the project.

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.

Is HDR Acceptable in Photojournalism?

The Washington Post raised some eyebrows last Friday after running an uber-saturated front page photo with the caption stating that it was “a composite created by taking several photos and combining them with computer software to transcend the visual limitations of standard photography.” After emailing the photo editor, Poynter learned that the image was simply an HDR photograph. While it’s a pretty common technique these days, some believe that it has no place in photojournalism,

Sean Elliot, president of the National Press Photographers Association, said, “HDR is not appropriate for documentary photojournalism.” The organization’s code of ethics say photographers should respect the integrity of the digital moment, “and in that light an HDR photo is no different from any other digital manipulation.”

“By using HDR,” he told me by email, “The Washington Post has combined different moments, and thereby created an image that does not exist. The aircraft visible in the final product was not there for all the other moments combined into the final, and that alone simply raises too many questions about the factual validity of the actual published image.” [#]

What complicates matters is that many new cameras (e.g. Nikon D4, Apple iPhone 4S) offer HDR features that create single images from multiple exposures in the camera. The Washington Post published a response to the controversy yesterday. Do you think HDR is an appropriate technique for photojournalists to use?
