Hi there,
I am fairly new to the ACES workflow, but I am really liking it so far. Color matching different cameras has never been easier. And I have downloaded and applied a few LUTs for ACES that I really like. The one thing I’ve noticed however is that LUT generation is significantly different. I did not expect my old LUTs that I built around Rec. 709 or LogC to work in the ACES workflow as they were designed around a different color science (DaVinci YRGB). What I did expect though, was that when I designed a new look in the DaVinci ACES color science and generated a LUT that the look I designed would be baked in using the new LUT. This was not the case. When I applied the new ACES LUT it looked nothing like the look I had designed. The color shifts I had made were similar, but the exposure, contrast, and saturation looked like they had all been affected when I didn’t touch any exposure, contrast, or saturation tools when building the look. My only conclusion is that I missed a step in the ACES architecture somewhere along the way that is being retained in the data of the new LUT I am creating, and then when I apply the LUT it is doubling whatever setting I missed. Can someone help me understand what I am missing? I am using DaVinci Resolve 12.5. My image procesing is 32 bit floating point, my color science is DaVinci ACES, my ACES version is 1.0.2, my input Transform is Alexa, and my output transform is Rec. 709. Is there something I am missing when building the LUT? Or something I should be doing differently?
Thanks,
Vincent Lomascolo
