​​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
​​
​​

​
​Goals

​
​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.

​
​Proponents

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

​Deliverables

​
​Proposed deliverables related to #1 include:
  • ​​Documentation outlining issues and potential solutions to minimize errors in exposure and white balance ssociated with converting camera data to ACES.
  • ​​Test procedures to verify exposure and color balance. • Recommendations on test equipment.
​
​Proposed deliverables related to #2 include:
  • ​​Documentation outlining the strengths and weakness of various IDT models (e.g. 3x3 matrices, 2D LUTs, 3D LUTs, etc.).
  • ​​Offer test procedures to camera manufacturers to verify camera spectral sensitivities. • Recommended defaults steps in P-2013-001 where options are presented.
  • ​​Recommended datasets.
  • ​​A reference implementation of the procedure specified in P-2013-001.
  • ​​Test procedures to verify the quality of an IDT.
