Adobe has posted a case study on its Web site detailing the use of After Effects and Photoshop in the VFX-heavy blockbuster 300.
Photoshop was used to create the concept and poster artwork, and for colour correction and rotoscoping of key scenes. After Effects was used to composite the live-action, bluescreen footage with the CG environments in some scenes.
The piece interviews the film's visual effects art director, Grant Freckelton, and DFX supervisor Tyler Foell from Pixel Magic, one of the VFX houses that worked on the film.
