Re: Unusual BW scanning phenomena. Viewpoints solicited...

Thanks Stephen, I did get some degree of relief in moving the
?brightness? slider all the way down to its lowest limit in Vuescan.
However that does reduce the otherwise lovely and sharp scan, which
takes place when brightness is left in the normal position. The Epson
Twain closest equivalent is the Highlight slider.
There would obviously be a generation lost in the re-shooting of the
photo itself, however, I am going to do that and let you know how it
turned out.
Thanks,
JFJ
