Research direction

No repository file, test, or entry point is named. Start by tracing the camera pipeline stages discussed in the issue, especially lens shading, gamma correction, and CCM application; done would be a documented, definitive ordering and whether CCM placement can be adjusted.

Written by the indexing model from the issue text.

Description

Just a clarification.

"Contrast" is the gamma correction in this image:

This means that the CCM is applied to the non-linear data once the gamma correction is complete?

Why I am asking

In case it helps I'll let you know why I am asking

We are trying to do spacially variant colour unmixing to remove colour desaturation that comes from the very strong lens shading. To do this we basically create a tensor which is a CCM for each pixel.

I am trying to linearise the calibration images and the images to be corrected. It is my understanding that I need to invert the CCM before I degamma? Is CCM coming after gamma hard coded into the pipeline or is there a way to adjust it?
