This is a 30 frame rotoscoping test of an explotion done in photoshop

If you want to give it a try for yourself take a look at the Rotoscoping tutorial here.

Photoshop can import QuickTime files and image sequences for editing and what not.  So I wanted to see how hard it would be to rotoscope some footage.  The result was the ability to make some great 2D effects using Photoshop.
