Hello Elle, I put together the ACES 1.0 OCIO config for The Academy. Hopefully I can help answer some of your questions.
Specifically, you asked " Does anyone use ACES in conjunction with ICC profile color management? If so, do they use OpenEXR to store RGB data? " We have found that many people that use ACES and ICC profiles convert their images to a 16 bit integer encoding before working with the data. The transfer function used for the encoding is usually one of the many flavors of log, like Cineon, ACEScc, LogC, a bespoke log-base2 transform and so-on. ICC profiles are then authored to expect data in that encoding. Example ICC profiles are included in the ACES 1.0 OCIO config's 'baked' directory. A growing number of people are painting directly on linear/HDR/scene-referred data as Photoshop has increased it's support for LUT formats that handle linear/HDR/scene-referred data more naturally than ICC. The Cinespace (.csp) LUT format seems to be gaining wider use in facilities that want to do this, as the format is now relatively well supported in Photoshop and a number of major applications used in VFX, like Nuke and Maya. Example .csp LUTs for the ACES and ACEScg space are also included in the ACES 1.0 OCIO config's 'baked' directory. I know your original question wasn't about ACES specifically, but hopefully that helps. If you have further questions about the ACES transforms, the OCIO config or the general ACES approach, feel free to ask directly, through the ACES Google Group or through the a...@oscars.org alias. We'd love to get feedback from the Gimp development team and user community.
