Test Strips
The timer can make test prints with any base and exposure increment. The timer
can make either progressive test strips where a strip of the paper is covered with
each exposure or it can make individual test prints in a series of increasing
exposures. The choice of test strips/prints is made in setup mode; the timer ships
with the factory default set to progressive test strips.
Progressive Test Strips
1. Make a base exposure of the entire sheet as described above. This exposure
should be below the expected exposure for the print so that one of the test strips
will show both the proper exposure and the exposures above and below.
2. Press the menu key until the display shows test strip mode
t0.5
and set the
desired step size with the up and down keys.
3. Cover a strip of the paper with a card and press the expose key. After the
exposure the timer will flash the total exposure, in stops, of the just exposed strip.
4. Advance the card across the paper and press the expose key for the next
exposure. Repeat across the sheet of paper.
The result should look like the example test print
at left.
The print was made at a base exposure of
1.0
and a test strip interval of
t1.0
. The middle
strip, at 3.0 stops, is correctly exposed and
chosen for the base exposure.
It also shows dodging and burning adjustments
to the base exposure. Note the adjustments are
in stops +/- from the central base exposure.
