[filmscanners] Re: NikonScan negative question (was Dynamicrangequestion)
From: "Dieder Bylsma" <scanners@spacemoo.com>

the only problem is that Nikon's scanning software is quite aggressive on
the
white points/black points and loves to make things super-contrasty, despite
what I've set in its preferences for black/white points of 0.01% each.

I don't seem to have that problem on my 4000ED with NS4 on XP. But I do
notice that green tends to crowd the white point end, so I set my Gain down
by .15 for that channel.
Gain is (I presume) the only way to affect how much light gets through the
film. For dark inages but with a maxed out bright region, it's tricky but
you can increase Gain and then twist the curves to prevent burnout, ending
with more shadow detail. However, I find NikonScan rather good at estimating
the available detail. I rarely get more out of a dark image without losing
it to noise anyway.
