I won't be much help in software that isn't Photoshop, because it's all I've ever used. But where I CAN help is this: often, it's hard to find help in the help files because you don't know a specific enough term to look it up properly -- you know what you want to do, but not, perhaps, what it's called. (You will have a slight advantage here over many users, because lots of things are generally called by what the photography world calls them -- color dodge or burn, for example.) But if you can't find what you want to do in the help file, call me, and if I know what you should be looking up, I'll happily tell you. Also, I can clarify anything you run into that's specific to the printing industry, like "dot gain 20%" or whatever, if you run across something with which you're not familiar.

Your screen is better than mine, though. Maybe I should ask you to do my color corrections. >:-)
