I am really not sure how to word this question. I have seen where a person in a photo looks like it has been cut out of it's background. So it's just the person without a background behind it. How can you do this??? Also, I have seen where multiple (4 or 5) poses of a person is put in one single picture...how is this done?? I have Photoshop CS4. I hope these questions make sense...it's kind of hard to describe what I'm talking about. THANKS!
