[filmscanners] Re: CS 5000 ED vs. Minolta ???



Since I have the Coolscan V ED, all this makes me glad I'm not shooting
slides.  I assume my scanner would have the same issue as the CS 5000.
Someday I'll probably get some of my old slides out and scan them, though.
And now I know that if I discover one that has edge softness I can't stand,
to remount it and try to get it flatter. If that fails, I might rephotograph
it with my slide copier, using very bright light, shooting with negative
film, and then scan that.
