A tool based on the ZCAM ,transfer Arri LogCv3 to JSH of ZCAM JzAzBz.
Added additional scaling of the J and S components to facilitate adjustments with the curve tool.
Thanks to Nick-shaw who provided some of the transfer fuctions. (https://github.com/nick-shaw/aces-ot-vwg-experiments)
Base on ZCAM color appearance model by Muhammad Safdar, Jon Yngve Harderberg, and Ming Ronnier Luo.
AWG_To_JSH provided a easy way for look development. Using AWGtoJSH 3x3.drx. Just like using vs curve in Resolve.
Or, you can simply split it into just the J C H channels for adjustment.
Added scaling slider for A, B components.

A tool based on the ZCAM for a more perceptually uniform increase or decrease in image saturation.
INPUT：Linear、CIE XYZ D65. Please using Color Space Transform, Tone mapping method:None, Gamut Mapping method:None.
Luminance Adjust：Adjusting the model's prediction of luminance. It can be adjusted to better predict the H-K Effect when there is significant spillover of color.
Saturation Suppression: Analogous to the Lift Gamma Gain color wheel, if you think of Saturation as a Gain on saturation, then Saturation Suppression is a Gamma operation on saturation. After testing, the recommended setting is 0.2 to get a comfortable result. This is equivalent to controlling the degree of "natural saturation".
