I'm working on a 10,000th pass on a project as I try to practice trial and error. Once everything is near where you want it before the transform node, it seems like you can make fine tuned adjustments more easily after the transform node. At least with RED Gemini footage. When I compare the results of other LUTs it seems easier to create those looks as well post transform node. There is also a good chance I'm doing everything wrong for the 10,000th time.
