No, not a detailed compare. I bring vuescan-scanned images into Photoshop in
hi-bit mode for further editing, and haven't seen any undesirable softness
there using cleaning alone. (The more intense grain elimination clean/filter
options 2 and 3 that go beyond IR-cleaning of course will soften an image.)
Except for scratch removal both versions produce very good images that meet my
needs for both web and print (Epson 1200). Vuescan 7 sometimes will give
better initial colors.
Ideal if Ed could implement it would be an additional filter option (in 7) to
use 6.7.5's IR-clean algorithm in the cases where it's needed.
This applies to my images, mostly from stage-lighting in theatre on higher
speed neg film. Might be different for daylight shots.
