In search of a D50 Editing colorspace
Does this statement below confirm ProPhoto RGB is D50? Or is it D65? On Sep 3, 2014, at 12:00 PM, colorsync-users-request@lists.apple.com wrote: A key point that many seem to have missed:
With ICC profiles, ALL editing spaces are effectively D50, including sRGB. If you examine for example the sRGB profile, you'll find that it converts device values to D50 colorimetry.

Melissa RGB is the name for the color space that represents the histogram (outside of soft proofing) and numbers (0-100%). It uses ProPhoto RGB primaries but an sRGB 2.2 TRC while the processing color space which has no name I'm aware of, is the same but uses a 1.0 TRC. So AFAIK, Lightroom and ACR use the same conditions as ProPhoto RGB proper expect for TRC. Andrew Rodney http://www.digitaldog.net/
The statement cannot be used to confirm that. Regardless, ProPhoto is defined as D50. -----Original Message----- From: "Millers' Photography L.L.C." <digitalimaging@dnmillerphoto.com> Date: Wednesday, September 3, 2014 9:13 AM To: ColorSync <colorsync-users@lists.apple.com> Subject: In search of a D50 Editing colorspace
