German photographer Falk Lumo has an interesting post on his blog regarding full frame and crop sensors. His theory is that camera manufacturers have created an artificial barrier between the two sensor sizes for business reasons, and that we’ll soon be seeing big changes in the camera world as this barrier disappears:
[...] there is an artificial separation between the APS-C and full frame markets. Artificial because less people still believe that full frame must be expensive. And artificial because image qualities beyond an effective resolution of 20 MP may simply require full frame. The new offers from Nikon (D800 and D600) therefore directly address this and may accelerate the disappearance of the artificial market separation. This is known as “supercriticality”: the market ought to offer uncrippled, full frame enthusiast cameras in the $1,500 segment but offers APS-C cameras instead. Supercritical systems “fall” into their preferred state after only small perturbations occur. Once this happens, a D800 type camera will be in the $1,500 segment.
He predicts that full frame cameras will soon be much more affordable and compact as mirrorless cameras eat into the APS-C market, leaving “cameras with a full frame mount but a half frame sensor” to be “a curiosity of the past.”

Paris-based photographer Marina Gadonneix documents the artificial spaces that are television studios while they are off the air and completely devoid of humans. The project is titled “Remote Control”.
For her project titled Mirrors, Swedish photographer Ilar Gunilla Persson photographed various landscapes with giant mirrors placed in them. The mirrors give the scenes an surreal and artificial look, but all the shots were captured on film.
Photographer Kim Keever creates large scale landscape photographs using miniature dioramas. He first creates the topographies inside a 200-gallon tank, and then fills it with water. He then uses various lights, pigments, and backdrops to bring the scenes to life for his large-format camera to capture.
We always get a laugh when news organizations or governments try to pass off bad Photoshop jobs as real images, but with the way graphics technology is advancing, bad Photoshop jobs may soon become a thing of the past. Here’s a fascinating demo into technology that can quickly and realistically insert fake 3D objects into photographs — lighting, shading and all. Aside from a few annotations provided by the user (e.g. where the light sources are), the software doesn’t need to know anything about the images. Mind-blowing stuff…

Artificial lens flare is an important part of making certain computer generated scenes look realistic, but up to this point creating realistic lens flare has been a task that requires a good deal of processing power. Now, researchers have come up with a way to simulating lens flare quickly and accurately, taking into account a large number of physical factors that cause the phenomenon:
The underlying model covers many components that are important for realism, such as imperfections, chromatic and geometric lens aberrations, and antireflective lens coatings.
The video above discusses how the technology works, and also touches on the science behind lens flares. The method is patent-pending, and will be presented later this year at SIGGRAPH 2011.
