This one works way better than I expected.
For best results, feed it a flash picture with a bright subject in a dark room. Candid cell-phone pictures of your mates taken while out partying are ideal.
It won't necessarily work well on EVERY photo, and even when it does work, you might want to clean it up a bit with further editing in photoshop. (My friend pointed out that her hair shouldn't be affected, for instance. To fix that, all you can do is copy the original image into a new layer before running the filter and erase the green stuff from her hair.)
Given the limitations, this Filter makes it amazingly easy to zombify your friends... and that's really all it was meant to do.
