If you’re a photographer and you follow the trends and fads of the business, you’re likely aware of the term HDR or High Dynamic Range photography. It’s sweeping the internet, and everyone wants to know how to do it. Why?

HDR photography creates a very surreal effect, where every part of the image is “properly” exposed and well defined. I think of it as hyper-realism, because a properly done HDR image (when done properly) is one that best reflects what I see with my eyes.

Technically, this is done by combining multiple versions of the same image, all of which have been exposed slightly differently. It’s easy to push the images too far, however, and ruin the effect - but if you’re good, you can create simply stunning photographs. » MORE

Trey Ratcliff is one of my favorite “unknown” photographers. He’s only unknown because he doesn’t really do this for a living, not because he potentially couldn’t. Since he first visited Chernobyl and published Part 1 of his two part photo essay from the hot zone, Trey garnered the attention of the online community and his blog has earned itself a lot of traffic.

For a living, Ratcliff works for a game company… in fact, he’s the CEO. During his travels, he takes along his camera and shoots high dynamic range images of (seemingly) everything he sees or can get close to.

Despite the “fad” impression I get surrounding the hype of “HDR” images these days, it’s tough not to love their rich, hyper-real quality. What’s nice about Trey’s photography is his use of HDR. Very few people who attempt HDR imaging seem to understand when enough is enough, and push their images too far. Trey’s photography could easily be misunderstood for impeccably lit traditional photography, but they still have that slightly processed look which is typical of HDR.

Go visit the two part Chernobyl Adventure over at Trey’s blog, “Stuck In Customs“.

For the guys at xRez, it’s all about “extreme resolution”.

We’re not talking megapixels here, we’re talking gigapixels - with resulting images that are so highly detailed, you can zoom in to even the tiniest object in the distance and bring it in with clear and crisp fidelity.

xRez is like a studio, or a collective of photographers who are commissioned for special projects. They have some unique and highly specialized equipment designed for the purposes of gigapixel level panoramic work, high dynamic range photography, large scale “full dome” panoramas, etc. It’s the sort of stuff we all dream of doing, but very rarely get a chance to.

By combining powerful 3d tools and techniques appropriated from the visual effects field, possibilites arise of new imagery and animation that are truly novel and unprecedented. Applications of these new techniques can range from experiencing stunningly large prints in fine art gallery installations, providing a substitute to live-action shooting in feature film backgrounds, and enriching a national park visitors understanding and interpretation, to name a few.

The team currently consists of Greg Downing (who specializes in 3D based imaging), Eric Hanson (a visual effects designer), and Ron Shirley (a film and photography major) and together they have worked on visual effects for numerous outfits and companies. All these guys are teachers as well as professionals, and they’ve got some interesting work in their online portfolio that shows off this gigapixel obsession.
