Re: camera color profiling

Why would you want to produce an ICC camera profile for PS when the native camera profiles for Adobe products are DCP obtained from DNG files ?

C1 uses ICC and I believe that certain conditions need to be met and one is that the file should be an 8 bit TIFF for Capture One

Re: camera color profiling

marameo - jpg is already compressed data from your sensor using a curve/some profile and once you ve saved jpg it is not reversible.
about profiling every lense - i thought/heard some lenses do have their own toning, just a tiny bit maybe, different contrast behavior due different ways of multicoating or not, how many lense groups etc. etc... i do use some classic retro lenses with less glas groups comparing to modern ones, like nikkor 85/2, 105/2,5 and some modern aswell, voigtlaender 58/1,4, schneider kreuznach 50/2,8 PC, cz planar 35... so i thought i better ask before i do some unnecessury work on it. i did read some articles and watched some videos about rawdigger/fastrawviewer. in one of the videos the author was explaining that most cameras do correct in about +/- 0,3 steps the embed jpgs (i shoot only raw) and he compared the hisograms looking for over- and underexposed pixels in both jpg and raw (with rawdigger) which were different...

Re: camera color profiling

It could be a tiff 8-bit full size (Adobe RGB) from DPP Canon with a linear curve. I think the assign profile is what C1 does internally.

Utterly pointless. The camera converts the raw into a standard RGB working space (sRGB or Adobe RGB (1998)).
If you can avoid shooting in JPEG!

If they support DNG correctly and fully, they should.

I see, so it looks like there is only partial support for DNG as I can find no mention of using anything other than ICC camera profiles.

No biggie for me as comparisons between it and ACR with Nikon some time ago showed no benefits and claims made by some of better rendering and sharpness seen to be without substance.
