NebThere is a private patch called Color Channels that is capable of doing what you want to do. It controls which RGBA color channels the subpatches can write to. By placing it inside a Render In Image patch you can split the image into RGBA and modify it as you'd like. Keep in mind this patch is not included in QC 3 because it is not yet released. Everything I have read says there is nothing illegal or immoral about using these patches as they are included in OS X but are not made easy to get to. That said, it might not be the best for a production compostion.
To find the private patches try Googling for Quartz Composer private patches.

How would I go about splitting a single image feed into RGBA or HSBA component channels, so that I can process each channel individually as images, and then reassemble (or not) later on in the chain? I'm using QC3 on leopard. Thanks! - Neb
