I’ve been asked to create an ODT for an animated feature, so serve:
- Texture artists working in Mari on Linux
- Lighters who are reviewing shots in Nuke
My objective was to create an ODT for DisplayP3 (which is essentially sRGB but with P3 primaries). This seems like it has potential as an alternative to sRGB that takes better advantage of the available gamut on our hardware.
(We’re calibrating Eizo CG2730 monitors with DisplayCal to generate a per-display .icc profile for CentOS 7.4).
I’ve been using the OCIO tool ‘generate_config’ on a custom CTL file that was largely adapted from the sRGB ctl script in OCIO 1.0.3. What I find with both my DisplayP3 ODT and OCIO’s default sRGB ODT is that the luminance is reduced to about 0.83 or 0.81 respectively, so relative to other elements displayed on the screen, a white image viewed in Nuke with the ODT will appear grey.
I’m getting some pushback from my supes about this and they’ve asked me to create an ODT that employs the display’s full available luminosity (so white looks white).
If that’s not the case, I hope you will humor some questions about what I should adjust in the CTL to build an appropriate ODT.
