16x MP.
If you have a Nikon LS-2000, the 16x multi-pass scanning will
probably produce better results.

1. In the Color balance tab, what is the difference between "Neutral" and
"Auto Levels?"
Neutral doesn't change the ratio of red to green to blue. Auto levels
uses the brightest point to determine the ratio.
2. Also
the media or something to that effect. No great rush.

Very interesting, Ed. How does the program know how much fading there was,
vs just a difference in what was in front of the camera lens?
