Brightness + Mult: These nodes concatenate in the following node tree. This setup
does not work well if you use a pure color in a single Mult node (in this case, pure
blue with a value of 0,0,1) because the zeroes drop the midtones out completely on
the red and green channels. The Brightness node is set to approximately 3, helping to
maintain the red and green channels when the blue multiplier brings them back
down (.3, .3, .8 in Mult1).
•
Monochrome + Brightness + Mult: This is identical, except you get a purer blue color
since you have made a monochrome image before applying the color correction.
Note that the Monochrome node does not concatenate with the Brightness node.

Lookup: This example uses a Lookup curve, setting the midpoints of the curve to .3,
.32, .8.
