Had a go yesterday with new version of IPP2 on Helium sensor and it seems to work nice now. I did test in ACEScc with Resolve and was really happy about it. We got the same images like client saw in their side and we could work without red provided transforms in the end of pipeline. In a way as ACES has nice rolloff we can do the same things in just adjusting the footage like we always do but they have done it in different technical lut’s and there is many of them.
Tech side in cam: it was RWG and Log3g10. All lit with household lights and nothing that we see on pro set. So one can imagine how good all would look with proper light setup.
For now it seems promising and things seems to work as they are intended keeping ACES in mind.
My subjective visual feel but still seems like good starting point for colorist. Does not matter so much which body DOP uses as colors are there.
