Question

I'm trying to figure out how to translate (even if roughly) RGB curves from Photoshop into Quartz Composer - and ultimately into iOS. Any ideas on the best way to do this? Thanks!

No correct solution

OTHER TIPS

For generating a LUT in Photoshop use File > Export > Color Lookup Tables.

For importing LookUp Table into Quartz Composer composition you may use JavaScript patch. Look at this post: How to use LUT with JavaScript?

Touching iOS development, you should get acquainted with Quartz Composer runtime implementation for iOS on GitHub (by Joris Kluivers). Find it here:
