Chris, first off, are you familiar with photoshop actions? They are "actions," written, or recorded, by photoshop users. What they do is automate certain techniques that you use over and over again. Some people sell them, some people give them away free. The one I used was a free one, I think, but can't remember where I found it. You might try http://www.atncentral.com/download.htm
There are a lot of great FREE actions there you can expirament with!
As I am still trying to educate myself.......can you please explain what you mean by a cross processing action? I love the effect but have had no luck applying it! Thanks for any advice you might be able to provide :)
