Loss of saturation

Apologies if this topic has been covered. I can't figure out why after saving my raw files as jpegs I loose saturation, mostly reds. When any other viewer opens the jpegs they look flatter then I had originally saved them.

TIA

What color space are you assigned to your JPEG on conversion?

Stop using Adobe RGB until you understand color management. Read this thread then the color management book linked from the book thread in my sig.

In the "save as" dialogue box I have only one color choice "ICC Profile: sRGB IEC61966-2.1"

I don't think I will ever understand colour management. I'll look at your link now.

BTW when "saving for web" the saturation loss is the worst.

Thanks for the suggestions

My color settings are:

In your raw convertor you're telling it to make the files Adobe RGB, you have to change it to sRGB. In ACR it's an easy option, but where it is depends on the version of PS you have.

Turn on all the "ask when ..." check boxes so it warns you of color problems. Once you do that you'll see you're opening in Adobe RGB.

Before you do "save for web" you MUST convert to sRgb. NEVER assign a color profile, always convert.

Checking off "Desaturate Monitor Colors By" seems to address the problem quite nicely

I would say it hides the problem, not addresses it. All you're likely doing is messing up the colors in a way that seems consistent on your PC. I don't have that check box ticked either though.
