ICC Profile not showing up in Mac LRC

[rajmc79]

I downloaded a ICC profile from a print company and added it to the ColorSync folder.  I restatred LRC and I can select in in the Print tab but in the Develop tab it won't come up there.  I attempted to add it but when I navigate to the ICC profile I downloaded it is greyed out and I can load it.  What I am I doing wrong.  TIA.

Edit, I am using LRC 2023 from CC

Check that the ICC-profile isn't CMYK based. Lightroom can only work with RGB based profiles.

ICC profiles are not applicable to the develop tab. They are only relevant to printing and exporting images. Camera profiles like you see in Develop are completely different beasts. They have zero relation to each other. ICC profiles define an output color space that your output file will conform to. Camera profiles describe the color repsonse of the camera and define some transforms to create a certain creative rendering of the colors. So basically output vs input.

@Jao vdL is correct. I didn't read your initial post carefully enough. The profiles in the Develop module are entirely different profiles. They have nothing to do with ICC-profiles. You can load them in the Develop module for soft proofing, but not as camera profiles.

Thanks. Yeah I am trying to soft proof in the develop tab to see the ICC profile what it will look like when I print but I can't see that ICC profile I loaded up.

 My earlier answer about CMYK still stands. Lightroom Classic does not support CMYK icc-profiles, also not for soft proofing.

Ok that is what I thought as well but I saw online that a user was using the develop tab to switch between profiles to see what a print would look like on various paper stock for a specific print company (whitewall) so they can see what will be printed (assuming monitor calibration was done correctly).  I found that was a useful thing to be able to know so you can adjust your edit to match what you want it to look like based on where and on what you will be printing.  When I go to the print tab and select the profile I loaded up notthing happens to the preview to see if what it will look like.  Am I miss understanding what the Print tab profiles selection is supposed to do on the surface?  Thanks.

What you saw was soft proofing. Soft proofing only works in the develop module, not in the print module.

You can only soft proof in Develop. All profiles available in the Printing tab should be possible to use in Develop's soft proof. There should be a check box for soft proofing in the bar below your image in Develop. If you don't see it, you can enable soft proofing in the view menu or by hitting S. You should then get a menu below the histogram that allows you to select profiles. If you don't see the profile you want, hit "other" in the popup and you should see it so you can select it. Again, all profiles available in the print panel should show up here. Lightroom cannot deal with CMYK profiles as already noted but they also should not show in Print either. You sometimes might need to click on "show display profiles" to see it if the profile was not correctly generated.

UPDATE:  I found out my error, I didn't have Softproofing selected, now I can see my profile that I loaded up.  Thanks everyone!
