I thank Ed for his excellent input. I downloaded his references and will
read them carefully soon. In fact, for a moment, I have been remembering a
very happy momemt of my life (including two complete mornings in the
assyrian rooms :-) ).
Now I am so delighted with the results of the "inverse color layer" that I
will not try another technic until I end the complete assyrian slides
collection. Tweaking the opacity slide in the overlay layer does miracles!
It is a pitty that all the corrections must be in 8 bits mode.
I got Ed's Vuescan many time ago, but I am now doing the first steps with
it. In fact, until now I only scanned slides and used Microtek Scanwizard
Pro. Now I am beginning with my old color negatives and B&W collection and
my first impressions with Vuescan are very good. I will try the effect of
VueScan's "Filter|Restore fading" on the greenish assyrian kings :-) .
