I'd try the secondary CC to select the part of the tonal range you want to adjust and then adjust the saturation of just that.

Saturation Adjust works quite different. It adjusts the color level based on the color level. You won't use it much but in some cases this is a smart filter.

Try adjusting the Black and White with the eyedroppers on the Low and High until you get them as near perfect as possible. Then lower the Gamma. Don't adjust the Saturation. Try that.

The Color Corrector or Secondary Color Corrector FX will give you less noise when increasing saturation.

They have a different saturation algorithm.

more info on this please! anywhere i can read about it? :)

I don't think there is anything about it in the manual.

If you play around / use test images, you can get an idea of what saturation algorithm is being used. It has to be HSL or HSV (sometimes I am unreliable because I get the two confused).

2- On the flip side, the Color Corrector FX will keep more noise if you decrease saturation.


Somewhat relevant information here:

http://www.colormancer.com/colormancer-color-correction.htm
search for "Saturation increased via Hue/Saturation adjustment (+87)"

Not trying to pimp my software or anything, but these are the only pictures I have that show the differences between saturation algorithms.

And then this is what can potentially happen if you use 1.000 compositing gamma IIRC:

Wow . . Thanks Glenn. Y'know having these examples of yours certainly made even more pennies drop for me. Very helpful.

I'm assuming that your s/w is purely for stills? Yes?

Grazie

Sebaz, we did something similar to what you are asking about to a wedding shot at our last VUG meeting. Here is what works for me:

1. Set white balance using the Color Corrector.

2. Select the face color in the Secondary Color Corrector and adjust to taste.

You might also use Color Curves to take a little off the darker colors which is where most of the noise will lie.

Yep.
