filmscanners: (examples included, ~25kB) exposure influence on noise level for FS4000 working on underexposed slides

[tom <ch_fs@yahoo.com>]

Hi,
Here are some examples of exposure influence on noise level for FS4000 working
on underexposed slides.
1.FG_properExposure - the slide was properly exposed so it can be a reference
2.FG_exp0 - underexposed (2stops) slide scanned with FilmGet (exposure auto)
3.FG_exp2 - underexposed (2stops) slide scanned with FilmGet (exposure +2)
4.vuescanLongExposure - underexposed (2stops) slide scanned with Vuescan
(longExposure) 
All scans have corrected gamma in the same manner in order to emphasize details
of dark areas.

We can observe that "FG_exp2" and "FG_properExposure" are  nearly identical.

Regards

Tom
