# Image Processing Pipeline

In Lustre, image processing order is pre-determined—the order in which you perform image processing tasks does not change the order in which they are processed. You can perform these tasks on different stations simultaneously and get the same results. For example, if you apply an input LUT to a shot from a Lustre Station, it will be processed before the colour grading effects created on the Master Station are processed, regardless of the order in which you apply them.

Colour grading may occur at the beginning, the end, or the beginning and end of the post-production process. In Lustre, the order in which you create image processing effects parallels the different stages in the post-production process. Each task corresponds to a menu.

The image processing is as follows:

1. The application of a CDL from the CDL menu.
2. The application of input LUTs from the Input LUT menu.
3. Initial primary colour grading from the Grading menu (with the Input button enabled).
4. RGB and Hue curves colour grading from the Curves menu.
5. Secondary colour grading from the Secondaries menu.
6. Sparks® plugin effects from the Effects menu.
7. RGB curves colour grading from the Curves menu.
8. Final primary colour grading from the Primary menu (with the Output button enabled).
9. The application of output LUTs from the Render | Output menu.

NoteDust removal operations are processed separately. Shots where artefacts have been removed are not updated in other menus until you render.
