After some period of time, I have looked into the Transformations.pdf to find more about the Primaries transformation and was surprised how greatly the document improved with a lot of new attractive example images and descriptions.
A very nice and illuminating document. Thanks.

Example of a shot with Primaries and without
I did the workflow for this shot twice, once with a Primaries transformation, once the same except no Primaries transformation. The Primaries transformation was not the last one applied. For what it is worth, you can compare how it looks with and without. Criticism welcome.
