capture the entire photonic information of a scene
with essentially infinite depth of field, meaning that pictures can be focused after
the photo is taken, and low-light conditions do not require a flash. Lightfield images are also “3D” without the need for stereo lenses.
Lightfield (aka “plenoptic”) technology was developed in the 90's: the first working prototype required dozens of separate cameras and a supercomputer. Professional plenoptic cameras
have been available for the past year; the Lytro
startup intends to release a consumer-ready shirt-pocket lightfield camera later this year. [more inside]

DSLR News Shooter
is a new photo site featuring the use of the latest HD-dSLRs like the Canon Eos5DmkII, 7D and Nikon D300s for news, documentary and factual shooting. By Guardian news photographer Dan Chung
, it's a place for professionals, educators, students and industry figures to discuss the practice and the art of cinematic photography in documenting the real world. For example, the time-lapse and slow-motion film of the recent 60th anniversary parade of the PRC

Ban on Camera Phones in Iraq
Q: What do you do if your troops take pictures of physical and sexual abuse in American-run prisons in Iraq?
A: Ban cameras, of course. What the people can't see don't happen.

The Kodak vs. the King
of the the Belgian Congo (aka the Congo Free State) from it's heyday under the personal rule of the very evil King Leopold
. The contrast between the photographs used by Leopolds apologists
and those used by his enemies
(lead by the remorseless E.D. Morel
) is probably unsurprising but interesting as evidence of perhaps the first propaganda war to be dominated by photography. Also, the first genocidal atrocity to be, very partially, documented photographically.
The kodak has been a sore calamity to us. The most powerful enemy that has confronted us, indeed.... Every Yankee missionary and every interrupted trader sent home and got one; and now -- oh, well, the pictures get sneaked around everywhere, in spite of all we can do to ferret them out and suppress them.

site which takes as its starting point Mark Twain and his anti-imperialist campaigns and branches out most impressively from there)

is nothing new
. 300 years before there was film people were using the idea of the Camera Obscura
to project images onto nearby surfaces. Using the process to capture the images onto film was a simple progression. But camera cases break, and leak light exposing the film to early.
Enter Thomas Hudson Reeve
who folds his own one time only cameras with the very photo-paper he presents as his finished work
. Only a simple brass plate pinhole shutter is reused and developing is done in the camera by pouring the chemicals directly in.

The myth of megapixel cameras
is explained here in detail, finally "illuminating" why digital resolution is often worse
than you'd expect. In brief, digital cameras interpolate to get a color image from a black and white CCD -- losing sharpness in the process, and taking up far more flash card space than reason dictates. Conclusion: buying into the latest technology
isn't worth the expense
, until camera companies wise up. Finally, evidence which backs up my faith in scanning photos taken on a (decidedly analog) Nikon N70! [via Honeyguide
