Preferences > Color > Rendering Intent?
« on: November 05, 2019, 09:03:24 am »

Hi,
 I am just starting out with learning Capture One on a demo install.

 I am processing my canon .CR2 files into the 16bit TIFF with ProPhotoRGB colorspace. My monitor display is referenced to a profile made with a X-Rite i1display pro.

 I am having misgivings about the appearance of the previews in Capture One, but suspect it is just my unfamiliarity with the conversion engine characteristics as I experiment with the adjustments. I am a long time Adobe Camera RAW user, and my old habits don't seem to translate directly, but I would like to learn to use Capture One as best I can.

 In my circumstance I think I should be using Relative Colorimetric, but want to ask to see if this is the best choice fro my circumstance.

 Thank you for any advice you may offer.

With such simple matrix style profiles, Colorimetric (ideally Relative) is your only option EVEN if software provides other options. IOW, there is no Perceptual table in simple RGB working space V2 matrix profiles.

Thank you.

FWIW, I was not asking about Process Recipe choices. I am using a ProPhotoRGB Process Recipe choice.

FWIW, I did not think I was asking about Proofing Recipe choces, but maybe I am and do not know it. I am just using C1 to convert to a 16bit ProPhotoRGB interim TIFF file, which I will work with in Adobe Photoshop and or Affinity Photo before exporting for web or print display. I guess I associate soft proofing with predicting how something will appear in some sort of distribution media. I have never spent much effort to soft proof.

I am asking specifically about the  Preferences > Color > Rendering Intent selection. In Photoshop I use Relative Colorimetric and it seems suitable for this as well, but I am hoping to confirm or learn further etc.

Thank you.

Right and again, even in Photoshop, when converting using such simple matrix profiles, you can pick something other than RelCol but that's ALL you'll get. Because the other two tables are non existent. I know, it's confusing to see the options for say Perceptual but you simply cannot make such conversions; no table exists in those profiles. So you're picking RelCol and that's what you're getting with those profiles. You could pick Saturation or Perceptual but again, you're not getting that kind of conversion, you're getting RelCol.


Now using printer profiles where three tables exist is a different story. And the one to pick is the RI (rendering intent) you visually prefer when soft proofing.

It seems the Preferences setting for rendering intent is about the preview
https://help.phaseone.com/en/CO12/Optimizing-Your-Workflow/Preferences-Customization/Global-Application-Preferences#item6
So if we talk about the display profile you use and the preview transform, it may be that it's a matrix-based profile -- OP should check that in the profiling software, but it's possible to create LUT-based monitor profiles in some software, e.g.
https://displaycal.net/#difference_lutcurves_lutprofile

When it comes to output from C1 and rendering intent, see this
