Trial and Error
Finding the best combination of brightness, contrast, and repeat val-
ues is largely a result of trial and error. Expect to try many combina-
tions
with
multiple
film
runs
and
grayscale
rejects.
Record
your
settings and readings carefully. Take the time to watch and learn how
the film reacts as you image and analyze.
Gauging the Effects of Changes
When making changes to the Brightness value, use boxes 12 through
16 as controls. Remember that you may need to tolerate imperfection
in box 16 in order to pull out the last bit of cross-over in the curves.
To measure the effects of changes to the contrast values, use box 2 as
your gauge. You may need to tolerate imperfection in box 2 to achieve
your best midtones. Therefore, when you are close to your final num-
bers, analyze the entire curve, not just box 2 to gauge the effects of
contrast adjustments.
Off-Color Slides
Make
sure
that
the
film
you are
using
is
supported
for the
module
you
are using. If you are using a supported film, you may need to adjust
the color balance settings to obtain better results. Variations in film or
processing can result in off-color slides even if you are using a sup-
ported film.
The PCR II Plus recommended warm-up time is at least 30 minutes.
Observe the warm-up period recommendations discussed in Chapter
