Back in February 2007, myself and Peter were confronted by the Performing Arts department to create a video of an actor on a magic carpet flying over different locations for a play, we decided to use Photostory for some of our background images and it made all the difference, when used right it has the potential to work fantastically!
The department head was happy!
Photostory is excellent for advanced and basic users alike with its simple control panels and yet advanced features. For help with photostory contact me on here and i'll be glad to give you a hand ;)
I'm sure Peter could put it up in the theatre as a greenscreen example?
