Hi,

after let the vuescan output a linear raw file, two common tasks left
to me: do color balance and do gamma correction. which one should be
done firstly?

another correlative question: i sometimes also need to a little curve
in photoshop. i usually do it on lightness channel in LAB mode, i
want to ask, does the curving also cause gamma changing?

thanks.

IMO, gamma first so you can properly SEE the colors (density wise).

Curves always affect gamma, just more selectively within the image than
simple level adjustments.

well, who knows how vuescan do it? gamma first or color balance
first?

You said you were generating raw files, right?
So VueScan doesn't do either one in that case.
If you mean you are post processing the raw files also in VueScan, then
I don't know. Ed would probably tell you if you email him.
