Quote - hey baggins...can you work with single color channels this way?...say for a faked chromatic aberration effect(by scaling up one of the channels a couple pixels),maybe some vignetting and fish eye lens also

..calling it "Lens" has me thinking of camera stuff :)

Hmmm. Chromatic aberration, not with one lens because it only gets to look at one point at a time. CA is a kind of blur and that means integrating data from multiple points in space. I'll have to think about whether or not there is some trick I can do with multiple lenses.

Vignetting and fish eye could be done quite easily.

Remind me over the weekend. I'll look into it. I'll be travelling all day tomorrow (actually sailing) and I'll forget.
