Magic shots, yes. After a photopass photographer takes a pic, then ask for a magic shot. They might ask you to pose a certain way.
If you ever see Donald Duck, try to get a pic with "him." He (they) have a personality of being super funny, and hamming it up for pics, imo.
If you're in WS at Epcot, around the IG, take some close looks around for meandering characters, OR, a photopass set up near the Friendship boats there.
If you can ride something that has ride photos a few times, try to time them right. I've seen a young kid timing Everest perfectly - looked like she was resting her head on her hands to sleep. 7d, Splash, Buzz, and Everest are easy to time.
Non photo pass: The speedway can make for some great poses before you load, OR, from the grandstands - I got a few great shots of our son having the time of his life driving. People Mover can get you some great shots, and holy balls, if you can manage it, you can take some incredible pics on the space thing (forget the name) - the rocketship spin ride that you take the elevator to? Astro - whatever?
