Input Device Transform (IDT) Implementation Virtual Working Group
Josh Pines - Working Group Chairman
Alex Forsythe - ACES Technical Lead -
Steve Tobenkin - ACES Adoption/Comms Lead -
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

How the ACES VWG Process Works
If you’re new to our Virtual Working Group structure, please note the following:
- Working Group Meetings are held on GoToMeeting
- Discussions are hosted on ACESCentral.com in the named VWG Discussions category
- Schedules, documents, to-dos, etc. are hosted on the named VWG workspace (i.e. you’re on the Workspace for this group: ACESclip Requirements Review and Revision)
- A list of all the active and past VWGs can be found on the Workspace Home: https://aces.mp/VWG_HOME

Group Proposal Form
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.
