Description: RGB + L Stuart Forman Suggested process

Here is a different technique that may get you a better result.
Dynamic crop your L,R,G,B to crop the edges
Channel combination RGB
DBE or ABE on the color (alternately, you can do ABE or DBE to the R,G,B channels separately and then combine)
Photometric color calibration on the RGB, (alternatively you can do Background Neutralization and Color Calibration, but I prefer PCC)
Stretch the color to nonlinear.
Then for your lum, do your lum processing as you would normally do it and stretch also to nonlinear.
When you have both the Lum and the Color where you want it, then do LRGB combination.
