Hi,
What about using the a and b curves of the tone curve, as a tutorial
somewhere on the DT website was suggesting ? increasing the slop of the
blue part of the b-curve should increase the blue saturation, from my
understanding. On the example below, the right side is the original,
whereas the left side corresponds to just a slop increase on the blue/green
parts of the b/a curves. Maybe too complicated and not subtle enough?

Yet, I don't understand why, when I compare the "original" photo from DT
and the screenshot provided by Fstoppers in eog, the DT one seems quite
dull compared to the other (whereas there should be no treatment).
Something I am missing ?
Pierre.
