Notice of Meeting - ACES Gamut Compression Implementation VWG - Meeting #17 - July 22, 2021

Recap:

  • Focusing on fleshing out the User Guide before the Implementation Guide - as we’ve got a few implementations coming out soon
  • CLF test pattern is good, but with very large values as well as NaNs and infs - which aren’t good for the gamut compression.
  • @nick has designed one for our uses, with patches & ramps of hue and saturation sweeps.
  • Then run the oiiotool command line comparison with the relative difference settings set by the CLF group.
  • @nick will post the oiiotool and the python code to generate the test image.
  • @joseph - do we also want to test with highly saturated commercial colors (Coke red, etc)
  • Should we ship a plotting tool / visual comparison aide? Possibly a colab using the python colour science library?
