I wish I knew photoshop but you can't learn everything.  I can use photoshop brushes in corel which comes in handy when doing textures.  Finally I have been able to trade my 2 and a quarter slr for a digital slr so now I can photograph my own cloth and textures.  Photo paint lets you edit avi, and animated gifs which paint shop pro doesn't.  Before learning 3d, I used to combine 200 plus photos to make one photo.  3d makes it a lot simpler once I designed my own characters.  I tell you one thing, there should be a program that worked with poser that actually made it easy to create your own character from photographs.  And I hate smith Micro.  My computer crashed and burned last month and have been trying to put programs back on.  Can't seem to update poser now.  Anyway that's my problem.  If I can help you with paint shop pro, just ask.
