Danny, it is good to hear from a friend here.  Thanks for helping me better understand.

When it comes to CMYK, I give that task to the ones doing the printing.

I saw the ability to  process out from Lightroom in Prophoto and wondered.  I do hear it has some advantage besides the color gamut but do not recall just what that was.  I need to go back and see just what Kodak says.  I could bite off more problems with the newer gamut and will likely avoid it until I have a properly color managed computer better able to handle 16 bit files.

I don't know enough about it to ask more.  Thanks.

Tom
