C1 colors different compared to PS, LR etc.

    Hi,
    For me it is typical error in your color managment.
    You have to be sure that the profile in your jpeg is the same than in the C1 view or output tool.

    Like Photocor I believe you have messed up with your color management. This is hard to support through a forum. Some tips though.

    Do not use the monitor calibration profile for your images, either to view or to process. They are not working space profiles like sRGB and AdobeRGB. That monitor profile is for the software to use and both CO8 and PS do that automatically for you when it is set up right in Windows.

    In Capture One, make sure your proof profile is set to selected recipe and noting else. Next, set sRGB in the recipe and process a JPEG.
    In Photoshop, Color Settings, set working space RGB to sRGB. Now open the JPEG.
    Another tip: make sure the background color in CO8 and PS are (approximately) the same like light grey or dark grey.

    Now compare the viewer of CO8 with PS. I would prefer to have the raw file in the CO8 viewer, and the processed JPEG in PS. Showing the JPEG in CO8 is not the best comparison to make (that is a personal opinion).

    Paul, that's without a doubt my favorite today's tip, thank you so much.

    Can you confirm that if I intend to print from within COP8 it is OK to set the proof profile to the appropiate printer profile? Thanks again.

    Cheers,

    Mogens,

    First, the tip to use sRGB was primarily meant for the OP to troubleshoot his setup. When all is well, one can start using larger working spaces like AdobeRGB and align the entire workflow for that purpose. For the record.

    Printing is another matter. No problem to use proof profiling for that, to the contrary, and monitor values with the Color Readout cursor tool for example (you won't see much visible change on screen, I think).
    Finally, when you print, the color management pipeline is rerouted to the selected printer and the process recipe profile should not affect your output.

    Assuming you let CO8 and the computer do the color management - not the printer - using a proof profiling with the printer's profile makes perfect sense.

    Thanks Paul, very clear and to the point. You're the man.

    I had (still have) a similar issue with JPGs. I imported JPG files into C1, set "basic characteristics" ICC profile to "JPG File neutral", curve "Auto". The metadata said Color space = "sRGB IEC61966-2.1", I exported the file (no adjustments were made) with the same ICC profile "sRGB IEC61966-2.1" and disabled sharpening.

    I expected the exported file would exactly look like the original, but it didn't!
    I cross-checked with Lightroom and DxO (imported and export), and both worked just fine.

    I actually tried this with self shot jpgs, as well as with a dowload from the C1 blog. I actually tried every meaningful (to me) combination in the basic characteristics and export settings. Same result, always slight (very subtle) changes (sometimes only to certain parts of the image) if I loop the jpg through C1.

    Not a big deal for me but remarkably nevertheless.
    Any idea what I am (or C1) doing wrong?

    P.S. I viewed the jpgs with MS Office Picture Manager as well as the MS default viewer.

    My guess is that you are double profiling by applying a profile to an image that already has an embedded profile.

    Something along those lines.

    Thanks Grant.

    That is an interesting guess, I did not know that double-profiling is possible. Anyone knows this exactly?

    Beo,

    I use the exact same settings as you mention, without issue.

    However, you make no mention of your proof profile setting. Paul explains about this setting above in a response to me: It should be set to "Selected recipe", except when proofing for print.

    Cheers,

    Hi Mogens,

    I don't remember what the proof profile was, so, to be sure, I tried it again with a new image downloaded from here:



    Proof profile set to "Selected recipe"
    Everything else as before, no adjustments, export with sRGB IEC... (same as the color space of the original file), no sharpening.

    As the changes are only subtle, I imported the exported file again, exported again and so on (loop). Each time I am doing so, it again makes subtle changes, so after 5 loops, differneces are easier to notice.

    It is not the best image for that, with other images I had more differences.

    Here is the final comparison (original vs. 5 times impor/ export), note the differing hue or the red brush and also the shadows opened (shown in white square):



    Nothing to really worry about, again, only subtle changes, and not an important use case;
    but it shows that (1) the color management of Cap1 is not understood by me (and probably others who don't have a diploma for that 😊 ), and that (2) Cap1 might possibly have a bug here, which might affect other file types too.

    Thanks for taking the time

    Just to be clear.......

    If I want to export TIFFs in ProPhoto RGB, and I'm editing using a Gretag Color Checker that appears in an image, are you saying that I should select View/Proof Profile/Selected Recipe and not View/Proof Profile/ProPhoto RGB?

    No doubt I'll be corrected in some way...! 😎

    Thanks.

    D.

    Ps. I'm not editing for printer, but eventual CMYK conversion.
