Capture One and ACES
Hello,
we are working on TV commerials and using ACES for some month now. (https://en.wikipedia.org/wiki/Academy_C ... ing_System)
In ACES you work with scene linear values. A gamma curve or tone-mapping is applied in the viewer or baked in the image writing process.
What we are looking for is a convenient way to convert camera RAW files to scene linear (linear light) values. Affinity Photo is the only commercial product at the moment which can do that properly to our knowledge. The batch conversion in Affinity Photo is not working in this regard, at least for now.
I was looking on the Capture One website to find some information how the image pipeline works. I assume it is a 32-bit floating point pipeline internally. Capture One has sadly no export option for OpenEXR files. But MacOS has the ACEScg profile already included for some time now. So it feels like there is not much missing.
What we are looking for is a camera raw developing, NOT applying any gamma curve which seems to be possible in Capture One (Linear Response) and then writing out the files as 16-bit float OpenEXR files. At the moment it works only with 16-bit TIFF files where you can apply the ACEScg profile. The results are quite good, but especially in the blacks there is appearing some clipping or maybe „banding“. We are testing with the X-Rite ColorChart.
Would it be possible to add OpenEXR as an image export option in Capture One?
Best regards

I'd like to second this. I need exactly this. I'm assuming this still isn't possible?
