Title: Pro Photo Color Space Question
Post by: Josh-H on January 07, 2008, 07:08:19 am

I know that Pro Photo is a Gray Gamma 1.8 color space - so it makes sense to set CS3 color settings to a Gray Gamma of 1.8.

However... if working in the Pro Photo space should the monitor be calibrated to 1.8 or still left at 2.2? Or.. does it even matter?

This one has me a little flumoxed...

Using Lightroom, which is a Pro Photo color space with CS3 for pixel editing Tiffs before softproofing for printing is my workflow. [yes.. finally dropped DPP in favor of LR's vastly superior control and workflow].

Thanks.

Edit - just thinking about this I think I may have answered my own question... I beleive from memory that the gamma of the display has nothing to do with the gamma of the working space. I think I read or heard this somewhere.. might even have been on this site. Correct?

This being the case the monitor should be gamma 2.2 with a gray gamma of 1.8 in the Pro photo space in CS3.

Doesn't matter in that the TRC or Tone Response Curve (a more appropriate term than gamma) of a working space and the TRC of the display do not need to match.
