Hi Shebbe,
Thank you for pointing out the new update for Resolve, I got that installed but haven’t noticed a difference yet (on my M1 iMac 2021).
I am currently looking at Affinity Photo next to Resolve on this iMac monitor with a fresh bracketed exposure image pair. In Affinity, the HDR merge was created using their default “sRGB IEC61966-2.1 (Linear)” ICC profile, and then I exported to .exr 16-bit half-float for import to Resolve. In Affinity Photo’s “32-bit Preview” panel, I have Display Transform set to “OCIO Display Transform” using ACES with the sRGB ODT. In Resolve, I am using the ACES 1.3 sRGB ODT. Affinity’s viewer is very saturated and red compared to Resolve.
If I change Affinity’s preview to “ICC Display Transform”, the colors now match Resolve’s ACES sRGB ODT, but still with a slightly higher exposure. It does not seem to matter to Resolve whether I enable “Use Mac display color profiles for viewers” or leave it off and use a Video monitor LUT.
@TooDee, if I render out an .mp4/h.264 of this frame with the tags set to Same as Project (ACES sRGB), Quicktime shows the video looking exactly the same as the Resolve viewer. Same result if I switch the project to ACES P3D65/PQ-1000nit and export as .mov/ProRes.
The reason any of this matters is that if our DP is making initial color adjustments in Affinity or creating a show LUT in Resolve, I need to know that:
A. He is not accidentally clipping the data.
B. The colors are not wildly differing from expectations when we get to Resolve.
C. We are able to view a shot in the proper delivery format so that we don’t get surprised at the colorist facility a year from now.
