I haven't tested it yet but it seems like the color checker software can now create camera profiles for CO

https://xritephoto.com/CameraICC

The new ColorChecker for CO looks like it could save me a lot of time in reproducing art photos in the future. When I tried it though (following the PDF instruction) the icc profile that ColorChecker created and saved could not be found by CO. I tried dropping the profile into other various folders associated with color profiles, restarting CO every time i did this. No luck. It seems that CO is very picky about which profiles get listed in the "Other" section of the icc profile section.

I'm on CO 11.1, ColorChecker 1.2 and Mac High Sierra

you are creating a "camera profile" for a specific camera model, are you not ... why in the world you are aiming for it to appear in the "other" section ? instead of making a proper file name for it to show up for your camera model ?

Because it says so in the manual. See attachment.

I downloaded the manual, and thank you for the link. I'm puzzled by these statements on page 2:

Capture One Workflow to Apply Profile
1. Re-Start Capture One software to recognize the new
profile.

2. Open the image where the profile will be applied.
NOTE: If images in the collection need to be white
balanced, white balance using the image with the
ColorChecker in it. Then manually use that white
balance setting in the rest of the images.

3. Apply the profile to desired image. The profile will
appear under the Other profiles list option.

Number 2 has me confused! Does it say to white balance using the color pick in CO and then apply the profile? Am I reading this correctly? Then what would be the point of creating a new profile.

One more thing, can I adjust the exposure in the color checker file before I create the TIFF? For example, let's say I over or under exposure the color checker and make the corrections in CO before exporting the image. Will that affect the overall look and accuracy of the ICC?

I'm not entirely sure how to use it after it's done. In the Color panel I select the new ICC in the Base Characteristics ICC Profile drop down box, but do I leave the Curve section to Auto or Linear?

Please help, dazed and confused.

Hi Paul, I was confused at first until I understood that the tool has a particular purpose.  It is aimed at photographers photographing say an original painting who want as accurate a colour match as possible.  They would set up the lighting etc and then take an initial shot of the colour checker followed by a series of shots of the painting(s) being copied.  Then when processing use the colour checker picture as though it was a grey card to set colour balance for the whole series and then the profile to get the best colour match possible.
The tool is not realy intended for generating general purpose profiles.

so the newly created profile does appear in the "other" section in your version of CO? Because here it is still nowhere to be found.

Yes, it appears in the Others folder as specified in the PDF. I'm on Win 10, build 1809 with all the updates.

Hope this helps.

You have to name the profile in a specific way to get it to appear in the area you want. It doesn't have to be in the Other folder. See existing profiles for guidance.

I have created three or four camera profiles with the ColorChecker Passport for Capture 1. While I think the profiles for my cameras used in Lightroom are excellent and make a HUGE difference, the profiles, from C1, in a word, suck. I keep thinking it's me and I keep remaking the profiles thinking I did something wrong, but each time the color is flat, unsaturated and just plain bad. I had high hopes, but at this point, I'll use the canned generic profiles bundled with C1.

I tried a few things like putting the profiles in different color sync related folders (user and system levels). Also I tried renaming them, as you suggest. But how? For instance a profile the is named CNNIRC09 gets listed in the "Others" folder, whereas a profile named CNN819RA (which rests in the same color sync folder) is not.

As ippolitois mentions that he got it working on a WIN 10 platform, I tend to believe it is an OS related problem (I'm on Mac, High Sierra)

But how?
for simplicity - see how P1 names camera profiles for cameras and where they put them ...
