This is only a prototype, currently 3D printed with a controller inside, but the concept remains the same. The camera searches the web for photos taken within a 35 meter radius, and displays the number found with a counter on the back of the camera. If the counter displays a number too high the camera will prevent you from taking a photo. When too many photos have been taken the viewfinder will display a red "X" indicating that it will not allow you to take a picture.
The camera was designed primarily to "help the photographer avoid contributing to the ever-growing mountain of duplicate images available online." This would pose problems for tourists who often seek popular places to take photographs while on vacation.
Schmidt has failed to mention the benefits of choosing this camera over a more standard DSLR design, currently there only appear to be restricting negatives. It is possible that more information will be available closer to release when more designs have been prototyped but currently I am struggling to see the benefits of shooting with this camera over another.
