The "Color|Image contrast" setting doesn't exist in VueScan any more.

The new "Color|Image brightness" option does some very
clever color processing which is new to VueScan.   I don't
think this color processing can even be done with Photoshop.

If you change the gamma of an image with previous versions
of VueScan or with Photoshop, you'll see that the colors change
subjectively quite a bit.  They change less with VueScan 6.4.7.

No, the gamma in the color space is what's used to encode the
image, after the "Color|Image brightness" processing is done.
