Troy Sobotka (sobotka) added a comment to T44341: Access to apx10 colorspace (as well as some others) missing in Color Management drop-downs.

DPX is actually a SMPTE standard, much like many other facets already within Blender. It is used almost exclusively to communicate display referred image encodings.

While we are at this patch, the default config should be chucked out. The ACES bits are entirely wrong, the legacy copied transforms from the SPI pack is completely wrong in this context, and a hundred other errors.

Not sure about this if only because it prevents transfer of CDL values to other applications. There is no basis value available in the CDL, simply an offset.

Troy Sobotka (sobotka) added a comment to T34684: DPX/Cineon : let OCIO handle color space conversions.

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_.

Troy Sobotka (sobotka) added a comment to T34684: DPX/Cineon : let OCIO handle color space conversions.

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. That doesn't even include revisions and other custom transfers.

If the plan is to improve color space support for image textures as well, then you either need LUTs for conversion in the kernel, or we can do conversion to linear (half?) float outside the kernel, at the cost of increased memory usage.

@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).

Troy Sobotka (sobotka) added a comment to T41287: Color Picker applies color management incorrectly in 2.71.

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.

@Antony Riakiotakis (psy-fi):

this last patch addresses the transfer curve portion issue but display interpolation is still done in a linear manner across endpoints of the triangles that make up the color wheel during display. Also you'd need to change the code in the vertical widgets to use the unmodified value for displaying the slider, see ui_draw_but_HSV_v. also would probably need to be hooked up in the update functions

It all makes much more sense to me now. I suppose the most relevant example of this for me is when I render/composite my image on my right monitor exactly how I want, yet when I drag the image to my left monitor the color is barely different enough to be annoying. While it is annoying, it's quite minor compared to shifting a fundamental aspect of building materials.

Sadly, all of the functions here make assumptions of the RGB reference space being sRGB / 709, which is likely unfortunate due to:

  1. Hard coded reference space assumptions are a Bad Thing(TM) and make the results entirely incorrect and / or unpredictable depending on an artist's chosen reference space.
  2. Work against and will cause bugs given a proper color managed system, especially with regard to correctly displaying color.

Troy Sobotka (sobotka) added a comment to T40131: Color ramp values limited to 4.875 maximum.

“Okay, then I say it seems the HSV<->RGB conversion used by Blender now works well only between 0 and 1. Above V=1, it is an extrapolation and goes to infinity quickly when converting from HSV to RGB.”
