Exporting in max colour space

NN635387830551012856UL
I'd like to export a tif to another application in the largest colour space possible.
C1 offers AdobeRGB.
I can't see Prophoto in the list of icc profiles, which would be great.
I do see "Embed Camera Profile'.
How can I keep all the colour info when exporting?
Should I just use the 'Embed..' option - if I am right in assuming it maxes out what the camera delivered in the first place?

Thanks in advance.

    In the Editing Options ICC field, if all you see is Adobe RGB and sRGB click on "show more" and it should open a large list of ICC profiles including ProPhoto RGB. If you can not find ProPhoto RGB you may need to download it and install it. ProPhoto will give you the largest color space.

    Interesting point about ProPhoto RGB for Capture One.

    I'd like to install ProPhoto RGB into Capture One but despite a lot of searching online I can't find out where to go to get the profile and/or how to install it into Capture One.

    Maybe you know how to?

    Windows Colour Management (or maybe Color Management) should provide a list of all the icc profiles available on your system as installed by Windows or various applications that you may have.

    I would think that any applications will, these days, use Windows Colour Management to store and register what they have provided and what else is available to them.

    Some of the profiles may be dedicated to printers and print media requirements or for scanners or perhaps projectors and therefore not really appropriate for anything except their intended application.

    In Windows 7 icc profiles can be found here:

    C:\Windows\System32\spool\drivers\color

    Presumably Win 10 is similar.

    As I recall C1 uses ProPhoto as its internal colour space by default.

    If ProPhoto is not available to you in colour management you can download the ProPhoto.icm file from various sources (note it's an ICM file you are looking for at that point) and install it. If you have other phot editing application installed it is likely you already have the profile somewhere but why it would not be registered with Windows colour management is perhaps something to investigate.


    HTH.

    Richard,

    You can download the ProPhoto RGB (also officially named ROMM RGB) profile from .

    Assuming you're using Windows, the file should be copied to the \WINDOWS\system32\spool\drivers\color folder. On a Mac, the folder is either /Library/ColorSync/Profiles (all users) or /Users/Library/ColorSync/Profiles (current user).

    Then, the profile should appear in any image processing software that doesn't have the Prophoto profile already built-in. However, note that the displayed name for this profile will not be Prophoto RGB but ISO22028-2_ROMM-RGB, even if you rename the file. This is because the internal name is displayed, not the filename.

    You can fix this and change the internal name by installing a small utility available here : (ICC Profile Toolkit). Download the MSI file and install it (Windows only). When the program opens, just open the profile and enter "Prophoto RGB" in the description field. Save and exit. The profile will now appear as Prophoto RGB in C1.

    Thanks all.
    Good tip about the renaming, Richard - I had installed it and couldn't see it until you had mentioned it would be under "I" rather than "P" in a very long list.
    It seems to me this profile should be installed by default by C1 if it is missing.
    This is far too under the hood stuff to ensure exported Tifs are not clipped of colour, which is a basic and common need.

    Thank you all for your very help.

    ProPhoto.icc wasn't already on my Windows 10 Pro system so I downloaded it and installed it.

    It now appears in the ICC Profile listings.

    Thanks again, much appreciated.. 😊

    No this is not ProPhoto RGB and can't be used as such. As far as I know this is a special printing profile BASED on ProPhoto RGB.

    You can get ProPhoto RGB and other profiles from here: https://sites.google.com/site/chromasoft/icmprofiles

    ? ? ?

    Could you elaborate a little ? On this page there's nothing indicating that the file available for download is for printing only (beside an indication telling that printing is the preferred output - which is not a surprise).

    Is the Chromasoft site more "official" than this site ?

    Richard,

    If you have any Adobe product installed on your system, you can also look for any file named Prophoto(xxxx).icm. Photoshop and Lightroom install that profile for their own needs. They use the original KODAK file. Other products like QImage or EasyHDR are using the very same profile.

    see here:

    EDIT; also see https://photo.stackexchange.com/questio ... r-spectrum

    There are device spaces and device independent color spaces. sRGB is a device independent color space created by a lady at HP as a space to standardize CRT's back in the day. Chris Cox at Adobe created Adobe 1998. and Kevin Spaulding at Eastman Kodak created RIMM and ROMM color spaces of which RIMM is used as ProPhoto RGB



    So my assumption that this is based on ProPhoto was wrong, but it seems to be different enough to not be used as a replacement for ProPhotoRGB
