Iliah, You mention: "Argyll makes excellent profiles for colour negative films, something no other profiler can do (export DNG from vuescan and bring it to RPP - and you will see)" Do you have color targets shot on negative film (I think Fuji used to once offer a negative film target) or do you shoot targets yourself on film? If the latter, ideally you'd want the blackest black & the whitest white on the grayscale gradient to map to the lowest exposure (clear film for a developed negative) & highest exposure (Dmax for developed negative) possible on the film, correct? How does one do that? Thanks, Rishi On Wed, Feb 23, 2011 at 2:16 PM, Iliah Borg <ib@xxxxxxxxxxx> wrote: > Gentlemen, > > I like you both.
