RE: filmscanners: Vuescan gripes



Actually this is what I experienced: B&W film (TMax 100 or 400, don't
remember), auto-exposure, defaults settings: the histogram of the raw file
had almost nothing in the lower half. I rescanned with manual exposure and
got it right, after a couple of trials... I don't remember the exact version
of Vuescan I'm using (I'm in the office, now), but I downloaded it less than
a month ago.

Thanks, Alex

Why would you need to check to see if the auto exposure is correct?
Has anyone ever seen a case where the "Device|Auto exposure"
option doesn't work optimally?

It's fairly conservative, and there shouldn't be many pixels in the
raw scan file that are above 95% of white.

The clipping of the cropped file is controlled by the
"Color|White point (%)" and "Color|Black point (%)"
options.  Is there a problem with one of these options?
