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.
