ZCAM for Nuke

Hi,

Just wanted to show a quick comparison between a few CAMs with sRGB.

  • First Column: Uniform Lightness Ramp, Constant Chroma (Varying Per-Row), Varying Hue
  • Second Column: Out-of-Gamut Colours
  • Third Column: First Column Converted to Luminance

CIECAM02

CAM16

Kim et al. (2009)

ZCAM

A few quick notes:

  • A significant portion of the visual artefacts are cause by OOG colours.
  • CIECAM02 and its CAM16 child do not work well with dark colourful colours.
  • Kim et al. (2009) exhibit some strange artefacts, there is no reference implementation so maybe we broke something.
  • ZCAM behaves the best of the 4 models, simpler is better.
