Hello All

Regarding the back plate schema, we plan to change the following color correction properties in accordance with the ASC-CDL specification to make these properties more interchangeable with various systems and to avoid any confusion around the meaning of those terms for **26.11** :

- luma:gain → luma:slope

- luma:gamma → luma:power

- luma:lift → luma:offset

These will be applied in the order of output = (slope \* input + offset)^{power}.

For more information, here is an article that discusses the ASC-CDL specification and how it is used: [An in-depth look at ASC-CDL based color controls - Pomfort](https://pomfort.com/article/an-in-depth-look-at-asc-cdl-based-color-controls/#:~:text=The%20specification%20of%20ASC-CDL%20was%20finished%20in,production%20process%E2%81%A0)

Kindly let us know here or via GitHub issues if there are any questions or concerns on the same.

Thanks,

Denise
