Input Device Transform (IDT) Implementation Virtual Working Group 

Document Workspace

Josh Pines - Working Group Chairman
Alex Forsythe - ACES Technical Lead - email
Steve Tobenkin - ACES Adoption/Comms Lead - email


This group is intended to : 
  • Determine best practices for camera manufacturers and camera operators to ensure digital camera material comes into ACES with the proper exposure and color balance. (e.g. a normally exposed 18% gray card comes into ACES as R=G=B=0.18)
  • Provide guidance and tools to supplement P-2013-001 in the creation of digital camera IDTs.


Below are the list of proponents for this work listed on the original proposal form:
  • EFILM, Technicolor, ARRI, RED, Sony, Canon, Panasonic, BlackMagic
