Digital Cameras Leave Unique 'Pixel' Fingerprints

Fingerprint image

This article reveals technology that could prove that an image was taken by a cerain camera based on the "fingerprint" of the camera:

In technical terms, Fridrich and her co-inventors Jan Lukas and Miroslav Goljan found that every digital picture is overlaid by a weak noise-like pattern of pixel-to-pixel non-uniformity. As with fingerprints, that digital noise pattern will be consistent among all images taken from the same camera.

Though this technology is intended to be used against child pornography (as it exaplained in the article), I think that the same technology could be used to prove the copyrights of photographers on their photographs. The only thing is that the cameras should be legaly registered (the fingerprints scanned). So later on when the camera changed the owner, you still can prove that an image was taken by your camera. Well, you got the idea.

Digital Angle Viewfinder for DSLR from Argraph

Zigview

Zigview - the World's first digital angle view finder for digital SLR. Here is how it described by the manufacturer:

ZIGVIEW simply attaches to the eyepiece of your digital or film SLR cameras and displays the image in real time on a 2 inch/TFT color display for easy viewing at any angle.

The Zigview is particularly useful for low angle photography where you would struggle to see through the viewfinder especially with macro work, high angle situations such as press work where it is impossible to see the subject when taking pictures over crowds, and for copy work, etc. Zigview makes it easy to see the subject without difficulty in these, and many more situations.

Zigview

Argraph offers two models of the viewfinder: SC-V100B - $249 and SC-V100R - $299. The more advanced one (SC-V100R) has additional capabilities, such as cable shutter release, interval shutter selease (intervalometer), and motion detection shutter release.

For some time now I was thinking about buying Canon Timer Remote Controller TC-80N3, which price is $133. But after learning about ZigView, I am strongly thinking about the ZigView-R (the advanced model). It combines the viewfinder with all those nice features. And it will be more compact - one piece instead of two.
