HPA Tech Retreat: Academy Color Encoding System Updates
By Debra Kaufman

Under the aegis of the Academy of Motion Picture Arts and Sciences, hundreds of motion picture and TV technologists created ACES (Academy Color Encoding System), a color management system to enable color decisions to be successfully retained throughout the workflow.
