RE: filmscanners: RE: filmscanners: Vuescan Blue's
On my LS-4000 scanning Provia 400F slides I usually end up at gamma 2.4, with a
brightness of 1.3 or so (white point 0.001). The histograms look fine when I
get into Photoshop. I wonder if the physical film type, or maybe the media
type and color balance settings change the gamma and brightnes requirements?

Usually use a gamma of 2.2 here in Vuescan, but I remember Mikael Risdael
suggesting a lower figure could improve results.
