After seeing the tutorials I wonder if AE could be useful for stills, too.
Spreading one picture out over 30 frames, adding an effect (maybe a lazer beam or something like that), and then use the one frame where it looks best for the final picture - would this be a bad idea, and maybe better done using PS?
Thanks for these links, Vovka! And also thanks for the awesome tutorial in area 51 with the music video. Now I know how it's done I can work on creating my own!
