The Rescued film project aims at developing and archiving film rolls that, for some reason, were left undeveloped. In this video they present their work, and more specifically when they discovered 31 rolls shot my an American from WWII soldier.
The compressive sensing blog Nuit-Blanche reports this publication: First-photon imaging. The technique allows to capture depth and (limited) reflectivity information using only a small number of photons (virtually in the dark).
Imagers that use their own illumination can capture 3D structure and reflectivity information. With photon-counting detectors, images can be acquired at extremely low photon fluxes. To suppress the Poisson noise inherent in low-flux operation, such imagers typically require hundreds of detected photons per pixel for accurate range and reflectivity determination. We introduce a low-flux imaging technique, called first-photon imaging, which is a computational imager that exploits spatial correlations found in real-world scenes and the physics of low-flux measurements. Our technique recovers 3D structure and reflectivity from the first detected photon at each pixel. We demonstrate simultaneous acquisition of sub-pulse duration range and 4-bit reflectivity information in the presence of high background noise. First-photon imaging may be of considerable value to both microscopy and remote sensing.
The following is an artist made animation approximating the 3D structure of IC 1396, a nebula and young stars cluster in the constellation of Cepheus. On his blog, the author, J-P Metsävainio, explains how he created this animation.
Three days ago one of my photos on Flickr was invited by the Yahoo! staff in a group for some news related use. I had no real idea where it would end up and supposed it could be an illustration for an article or maybe their blog. I accepted nonetheless.
Attending a photo exhibition on Sunday motivated me to take my camera with me again. Not to go out and shoot, rather just in case, for those “would make a nice photo” moments.
While commuting back from work in a half empty train on Monday, there was such a moment. This man sat in front of me and soon he tried to sleep. But although his eyes were closed, I could see he wasn’t sleeping (unlike so many Japanese commuters who just instantly fall asleep, often in the middle of checking their mails). His face looked calm and unworried. With the empty seats, I thought it would make a good image as soon as some motion through the window would contrast with his quiet looking.

But before that moment came, another commuter sat next to him. I spent a while wondering if I just missed the shot or if I should take both of them anyway. I liked his face and kept staring at him, after he gave up on sleeping, waiting for an eye contact so I could take his portrait.
That moment didn’t come either. Finally I took my camera and aimed anyway. After a few seconds, I pressed the button.
He looked at me, and smiled.
