Can you explain exactly how you " look at the share book pre print"?
Also, why sRGB, it's not a very good RGB (though that doesn't explain your symptoms).
What I have to do is prep the book (I only do a few pages as a test). Then they let you share the book before purchase so I mail it to myself.
I shoot raw, work in Profoto RGB, then a MyPub tech told me their color space is sRGB so in PS, before saving I convert my color profile to sRGB.
An Adobe person at Photoshop world said he had a similar problem and told me to convert so the pics do not get dulled out.
I am doing some test pages with output color profile in Adobe RGB and in sRGB.
Any suggestions? I have set my LR color space to ProfotoRGB and my PS working space to Profoto RGB.
If you go into Photoshop's preferences > Performance and click on Advanced in the GPU, see if reducing the setting to Basic helps. Try your color conversions again.
Will try that. Thanks. It will take a while as I prep the pages for my book. Will do it both ways and compare.
I don't have the reference handy but at normal or higher PS will cause the GPU to remap the colors improperly.
I just looked at that setting and it was on BASIC. That must be the default because I never touched that setting before. Do you suggest I change to normal?
I finally got to my references. This had to do with "soft proofing" on screen in Photoshop.
So this may not help you at all. Re: Strange sRGB soft-proofing behavior So go ahead and leave that setting at Basic.
However there is a Color Management forum that you also go to and see if anyone has answers for your particular problem.
Here is the link: Color management
I hope they can help you out.
Thank you so much for your time and help…..I will try your suggestions …..Tomorrow I will be able to contact Adobe for phone support and they might have alternate suggestions.
