I know that CS4 has some very interesting interesting features and new tools. Even though I do not have CS4 my son took a seminar on it a week ago and has been driving me crazy trying to explain everything he was shown. I'm afraid the old bucket is fairly full and can take only so much at a time. I suppose I must break down and purchase it but I have been challenging myself in the last few months by trying to only produce photos that can be made in the camera. I have only used Photoshop for those things I could do in a wet darkroom. It has not only been a lot of fun but more satisfying. And thanks to Henning and Geoff for their inputs on the technique.
