Troy Sobotka (sobotka) added a comment to D2547: Color Management: Allow selection of the OCIO configuration in the User Preferences.

Ok, I think we have really different ideas about UI design here, I don't think we're going to agree about what the best solution is. I strongly prefer names that indicate purpose rather than implementation, orthogonality of functionality whenever reasonably possible,

Troy Sobotka (sobotka) added a comment to D2547: Color Management: Allow selection of the OCIO configuration in the User Preferences.

I think the filmic transform is very important. I have looked into the ACES config in detail and I believe what I am proposing is consistent with it, but maybe I'm misunderstanding it then.

If we look at the "Utility - sRGB - Texture" color space in the ACES config, it converts from a wide gamut reference space to linear sRGB with a matrix transform, and then to sRGB with the sRGB EOTF. What I'm proposing is that we do the same for image textures when we adopt wide gamut. If the intention for filmic with wide gamut is to do the same as ACES here, that's fine with me.

Troy Sobotka (sobotka) added a comment to D2547: Color Management: Allow selection of the OCIO configuration in the User Preferences.

I think the OpenColorIO design and existing implementations and configurations are clear, color spaces and transforms are not the same thing. Being able to specify an absolute color space rather than a transform relative to some other color space is critical for making exchanging of image files between applications work.

Troy Sobotka (sobotka) added a comment to D2547: Color Management: Allow selection of the OCIO configuration in the User Preferences.

The image setting here is not a transform, it is the color space of the image file on disk. If there are multiple ways to transform to/from that color space, that should be a separate setting.

Troy Sobotka (sobotka) added a comment to D2547: Color Management: Allow selection of the OCIO configuration in the User Preferences.

But that's kind of my point, calling it just "sRGB" is entirely standard in 3D software and accurately describes the color space.

Mar 10 2017, 12:50 PM
Troy Sobotka (sobotka) added a comment to D2547: Color Management: Allow selection of the OCIO configuration in the User Preferences.

For this we would use a name like Linear sRGB, Linear BT.709, .. to distinguish from sRGB. The way I understand the design of OpenColorIO is that this is a place where you give the name of a color space, not the name of a transform. I don't think anyone will be confused in thinking that selecting "sRGB" will save linear.

If we can get better support for roles in 2.79 I doesn't really matter if it's called Non-Color or Non-Color Data. If we don't get better roles in 2.79, we will need compatible names.

Troy Sobotka (sobotka) added a comment to D2547: Color Management: Allow selection of the OCIO configuration in the User Preferences.

For example if I set a normal map image to Non-Color now, that does not exist in filmic and it will use the SRGB EOTF, and the render will be wrong.

The only reason we are having this discussion is because folks are actually using and trying the colour management transforms. At least part of that I would attribute to the clairty of the configuration which has all portions operating together.

Troy Sobotka (sobotka) added a comment to D2159: DCI-P3 Wasn't Showing.

First, DCI-P3 is a specific shift in chromaticity to the DCI-P3 basis primaries. I haven't confirmed that the correct shift is going on yet with the one that is in the config, and I would not hold my breath as the configuration was cobbled together, mixing and matching transforms.

It has nothing to do with specs. It has to do with transfer curves, something that everyone in the motion picture world deals with every day. It isn't complex if imagers can select the damn colourspace, just as they do with _every other RGB format out there_.

If one examines the SLog, VLog, CLog, and all of the other variants at HPD's ACES repo here https://github.com/hpd/OpenColorIO-Configs/tree/master/aces_1.0.1/luts, one can see the problem; it is impossible to hard code all of the camera vendor transfer curves into Blender.

@Troy Sobotka (sobotka)
In general artists work in srgb space for videos and adobe rgb for paper. Then do a color conversion to match the output device. So srgb is good even if your final output is different (rec709 dci or whatever). At least this is how they recommend to work at Eizo (see page 13).

Forcing an artist to enter linear values instead of sRGB is the same as forcing someone to enter binary numbers instead of decimals. Linear values don't mean anything to artists. Artists are used to Photoshop or Painter that use sRGB space, the same as almost any graphics application around.

@David Black (david_black) You are mixing apples and oranges when discussing Photoshop. Photoshop operates on curved non-linear display spaces by default, and I believe it only recently, if at all, color manages the wheel. So it is in no way linear, nor even belongs in this discussion.

Then the UV picker is screwed again.

I've tried to do a very simple example here with scaling. A simple 8 bit sRGB PNG is embedded.
