Color Spaces using 1964 10 deg Observer
Hi all! Does anyone know of any RGB color space whose chromaticities were measured using the CIE 1964 10 degree standard observer? I'm researching this list: ACES2065-1 ACEScc ACEScct ACEScg ACESproxy ARRI Wide Gamut 3 ARRI Wide Gamut 4 Adobe RGB (1998) Adobe Wide Gamut RGB Apple RGB Best RGB Beta RGB Blackmagic Wide Gamut CIE RGB Cinema Gamut ColorMatch RGB DCDM XYZ DCI-P3 DCI-P3-P DJI D-Gamut DRAGONcolor DRAGONcolor2 DaVinci Wide Gamut Display P3 Don RGB 4 EBU Tech. 3213-E ECI RGB v2 ERIMM RGB Ekta Space PS 5 F-Gamut FilmLight E-Gamut ITU-R BT.2020 ITU-R BT.470 - 525 ITU-R BT.470 - 625 ITU-R BT.709 ITU-T H.273 - 22 Unspecified ITU-T H.273 - Generic Film Max RGB N-Gamut NTSC (1953) NTSC (1987) P3-D65 Pal/Secam ProPhoto RGB Protune Native REDWideGamutRGB REDcolor REDcolor2 REDcolor3 REDcolor4 RIMM RGB ROMM RGB Russell RGB S-Gamut S-Gamut3 S-Gamut3.Cine SMPTE 240M SMPTE C Sharp RGB V-Gamut Venice S-Gamut3 Venice S-Gamut3.Cine Xtreme RGB sRGB I suspect that if any of these do, it might be the ACES or other cinema spaces. My understanding, however, is that VFX/cinema standardizes on the 1931 2 degree. Outside of RGB, presumably all the major CIE device-independent spaces allow both. But if anyone knows of any other spaces that use the 1964 observer, I would love to know! I am also curious why we are not turning to the CIE 2015 revisions to the SOs. I don't see anyone using them anywhere. Thank you! Very best, Jeff Jeff Nova Chief Executive Officer Colorhythm https://colorhythm.com Mobile: +1 510-710-9590 Main: +1 415-399-9921
Misfire. Should have read " whose chromaticities were BASED" not "measured." - J Jeff Nova Chief Executive Officer Colorhythm https://colorhythm.com Mobile: +1 510-710-9590 Main: +1 415-399-9921 On Wed, May 17, 2023 at 10:56 AM Jeff Nova <jnova@colorhythm.com> wrote:
