What would be very interesting, is if you could mod the device to work with a better camera. Then, it would probably be useful in the photography industry. Maybe it would allow you to correct issues with lighting? It would allow someone editing pictures to easily select a part of the picture in the foreground or background. With selections being much easier, you could enhance specific parts of photos to make them stand out around other less-important parts without much effort at all.

I'm sure there are many more applications for this technology in the photography and even videography industry. Any ideas?
