Thanks, Frank --
Yes, I do follow the VS recommended workflow, and I haven't yet taken
the step (or expense) to calibrate my monitor beyond Adobe Gamma. (I
do intend on getting the Wolf Faust target, though, so thanks for the
link.)
I recognize that there's a difference between the reflective photo
media and the transmissive screen image, but I think this is just part
of my larger educational need. What I am looking for in a tutorial is
to learn answers to "if skin tones are too orange, do this", "if the
greens are a little flat, do that". I'm still a novice at this kind
of thing, so I'm looking for help on how RGB channels combine to
produce the colors I see on my screen (and, hopefully, then relate
those to the reflected colors of my prints).
Interestingly, I changed my workflow yesterday and discovered some
settings that gave me colors closer to what I saw on my hardcopy
photos. I used VS to produce raw files and then used VS to scan from
the files; to correct the colors, I found that if I
(1) reduced the overall brightness
(2) checked "restore colors"
(3) boosted the brightness red to 1.25
(4) reduced the brightness blue to .8
(5) and left green unchanged
that I obtained scanned images that looked pretty darn close to the
original photos. Which really makes me question - with dismay - the
colors of all the negatives I've previously scanned. :-(
But it's a learning process. I find it interesting how my workflow
and approach changes/evolves as I plod through a 4" binder of
negatives. The scans I'm getting now are a huge improvement over
those from the start of my project.
Thanks again for your suggestions.
