I recently purchased PS CS2 though I already had Elements 4. In processing my travel photos for print publication in magazines, is there a general rule on when to use CS2 or Elements 4? Eighty % of the time the corrections are minor and auto levels and auto color plus unsharp mask will suffice. Would I, for instance, do the easy stuff in Elements and use PS for more serious manipulation? Is there somewhere online where I can compare the differencies between them? Thanks.
