Can't change RGB Color Management Policies in Photoshop...

Hi, 

 

When I click on the drop down menu next to RGB in 'Color Management Policies' under 'Color Settings' - I can see that there are three options: 'OFF', 'PRESERVE etc', and 'CONVERT etc'.  I would like to change to PRESERVE, but it is not letting me.  I can only select and use OFF.

 

I'd really appreciate any insight into why this might be happening.

 

Cheers!

This will happen if you use the monitor profile (Monitor RGB) as the RGB working space.

Don't ever do that, it disables color management.

Use a standard profile like sRGB or Adobe RGB as the working space, which will allow you to choose Preserve embedded profiles.

Note that the working space only affects new files that you create inside PS (using File > New), and also acts as a fallback if you open an untagged image.

If you set Missing profiles to Ask when opening, PS will let you choose which profile to assign to an untagged image.

If this box is unchecked, PS will automatically assign the working space.

    Thank you so much for the tip!  I have to say I find the whole colour profile thing quite confusing.  Images look so different on my mac vs my pc, vs my phone.  Obviously each screen is different, but the variation in colour and contrast can be quite extreme.

    That's why color management was invented. If you use it correctly, everyone that also has a properly set up system will see the same thing, anywhere, on any system and any display. Phones excepted, no support there.

     

    To use color management correctly in Photoshop basically means doing nothing. It works out of the box at default settings (with a few minor exceptions). Most color management problems happen because people do something when they shouldn't.

     

    To take full advantage of this, you also need to profile your display, so that it too has an icc profile that can be used in this equation. This is not to be confused with the document profile! All color management requires two profiles, a source and a destination. If you use the same profile for both, they cancel each other out and turns color management off, as Per points out.

     

    Calibrators are not as expensive as most people think, and most experienced users will consider that an essential piece of equipment.
