to my eye it appears to give a wider tonal range - digs a bit more into the shadows, holds the highlights - that sort of thing
no doubt it's very subjective, which is why I said it seems to work for me - I went back and reviewed a few samples looking for something to explain the difference visually, and the differences were sometimes so subtle that I knew they would not be convincing on the net
However, although this degree of difference does not happen all the time, these recent examples with the Hexar Af and Plus X startled me when, after scanning hurriedly as a straight negative scan, I went back and scanned as positive and inverted in Gimp.
It is a Ferrari, and it is Ferrari Red :cool:
in this scan as negative it looked ok - I was not unhappy with it - this only has a touch of sharpening

but when scanned as positive and inverted it took on a new look - the relationship of colour in greyscale and the tones were much better - ditto for this one; just a touch of sharpening

this was how the inverted version looked with a touch of sepia toning
