In a very cool way Flickr is sharing the camera information of its users through a new Camera Finder page they have put up. Not only interesting but a great way to know your getting a decent camera (after reading reviews on Amazon of course).

How do they do it? They are probably reading the Exif data that is embedded in every Jpg image taken from a digital camera. This data identifies things such as camera used (duh!), date/time, was the flashed used, focal length, image compression, and much more.

Also, thumbnails of the original image can sometimes be found in cropped JPG images (remember the TechTV girl Cat Swchartz incident), so watch out. This isn’t in the Exif data but show how other information can be stored within.
