Image Noise: Bad for photographers, good for forensics

All cameras introduce varying degrees of imperfections. While these imperfections are undesirable for the consumer, they can be highly informative in an image forensic setting. Sensor imperfections, thermal effects, compression, etc. each introduce noise in the image. This noise manifests itself as slight variations in the recorded intensities of light. If a portion of an image is altered then it is likely that the underlying noise pattern will be disrupted. Differences in the noise pattern can therefore be used to detect and localize image tampering. Soon photo award shows will have their own CSI departments. Read the full research article here.

Alan Friedman’s Astonishing Photographs of the Sun Shot from… his Own Backyard

Alan Friedman points a telescope skyward from his backyard in downtown Buffalo, directly into the light of the sun. Using special filters attached to his camera, Friedman captures some of the most lovely details of the Sun’s roiling surface. The raw images are colorless and often blurry requiring numerous hours of coloring, adjusting and finessing to tease out the finest details, the results of which hardly resemble what I imagine the 10-million degree surface of Sun might look like. Instead Friedman’s photos appear almost calm and serene, perhaps an entire planet of fluffy clouds or cotton candy. Check out his work here, his Tumblr here and TedX talk he gave here.
