<x-tad-bigger>Is there a way to update changes to image faster on the screen?  I tried to change brightness of a 2 MB photo image, and it is too slow.  I, however, tried another program, and it changes brightness instantaneously.  Any help would be greatly appreciated.</x-tad-bigger>

Are you sure the problem is about drawing on the screen ? it may also be in brightness calculation.

How do you draw the image to the screen ? which type of NSView ?

You may profile your program with CHUD Tools to see exactly in which functions your program wastes time.
