Phase One has optimized the world's first fully automated multispectral imaging solution, which will make it faster and easier for art conservation, forensics, and science professionals to examine delicate subjects.
Here is a little exercise to show how we can do things in this modern world. This is not one of those whacky geo-location stunts, this is just ordinary research, some simple geometry, and some careful guessing.
Fujifilm has announced a unique, specialized version of the GFX100 camera. Still insisting on calling it a "large format" camera, this latest version can shoot infrared images at either 100 or 400 megapixels thanks to newly-added pixel shift functionality.
UV photography has many obstacles. Ultraviolet light, or light from 200nm – 400nm in wavelength, is notoriously difficult to image with normal camera equipment. A normal digital camera will record images in the visible light spectrum, or 400nm – 700nm in wavelength. To unlock sensitivity to those shorter wavelengths, a camera has to be physically modified to allow passage of light below 400nm.
A recent photographic analysis technique developed by Professor Siwei Lyu and his team at the University at Albany - SUNY could lead to better forensic analysis of altered images. The technique takes advantage of the fact that, when splicing two images together, each will bring with it the specific noise pattern of the camera it was shot with.
So, when analyzing the obviously fake image at the top, the flamingo Tiger Woods is using in lieu of his golf club shows up as having a different noise pattern than the rest of the image.
People often laugh and poke fun at the cliche of impossible image enhancements seen in TV shows and movies, but you won't be laughing when you see what SmartDeblur can do -- you'll be gawking in amazement. Created by programmer and image processing expert Vladimir Yuzhikov, the program can magically reveal details in photographs that are blurry due to poor focusing and/or shaky hands.
The camera obscura has been around for a long time (Middle Ages long) and typically consisted of a box or room with a hole in one side through which an image of its surroundings could be formed. As you can see from the example above, any room -- in this case a bathroom -- can be turned into a camera obscura given a small enough "aperture." Unfortunately, most rooms have big, blaring windows that let in too much light, and the only image formed on the opposite wall is a shadowy blob.
In the name of forensics, however, Antonio Torralba and William Freeman from MIT have discovered a technique by which they can turn any windowed room into a camera obscura, using a couple of stills of the room to magically gather an image of the outside world.
