That information should be provided from the colorist who did the grade. For instance my grading monitor is set up to Rec. 709, with a 2.2 Gamma. So any master that I export for a DCP, that will be the color space and gamma.

I think this question has been asked before, but I am still not comfortable with it. I understand the difference between these two color spaces, but how do I know what to choose when working with DCP o Matic? How can I check the color space of a video file? And what do I do if I do not know it? When working with HD Material, is Rec 709 the common color space? When I export from Premiere to Avi uncompressed, TIFF sequence or H264, how do I know what the color space is? Any answer is appreciated!
