What are people using/doing to create photo filters or photoshop like effects on iPhone OS? Things like B&W, sepia, cross-processing, 'vintage' etc. I see ImageMagick can probably do this with a lot of futzing around, any other options?

Thats a pretty nice looking drop in solution as long as you're ok w/supporting 5.x only (which is really the majority case at this point anyway). – Shizam Apr 12 '12 at 19:06

ImageMagick was not the way, its to slow. The solution is to access the raw byte data and modify the RGB values pixel by pixel using, among other things, 5x5 matrix transforms. Here is a good place to start:
