RE: filmscanners: Nikonscan3.0 and LSIII

With regard to Vuescan cleaning and ROC in version 7.0+, I found by 
accident that there is a huge difference between 48-bit 2700 ppi scans on 
my LS-30 (where that should have been more than enough) and 64-bit, 2700 
ppi settings. In the former, the filters didn't seem to work worth sour 
apples. In 64-bit mode, it was a revelation. The magenta flesh tones in my 
25-year-old slides suddenly turned human, in most cases. A little work in 
PS4 (I'm way behind the times, I know) and I had very presentable images, 
at least at the standard of family photo album usage. Since those old 
slides were precious (like my mother's 80th birthday party, several of the 
people now long gone) it has helped greatly to justify my investment in the 
scanner, as that was a primary motivation for me.
