sure. Continue until the measured optical density equals the base
optical density setting (at least to within 5% of base optical den-
sity setting).
10. Press the key next to the Next Calibrate field to advance to Reci-
procity Calibration.
IMPORTANT! To ensure AEC optical density is cor-
rectly calibrated to the desired "base" optical density
setting, either the AEC Ref value must be adjusted to
obtain the desired base optical density (which is veri-
fied in the exposed film using a densitometer) or the
Optical Density setting in the AEC Optical Density
Calibration Menu must be set to the actual measured
film density. For example, the calibrator would like
the system AEC optical density setting to be "1.30".
The calibrator must then adjust the "AEC Ref" value
until the actual measured optical density of the film
is 1.30. However, if the actual measured optical den-
sity is 1.29 and you decide not to continue to adjust
the AEC Ref to achieve exactly 1.30 film optical den-
sity, then change the Optical Density setting in the
AEC Optical Density Calibration Menu to "1.29". Note
that 1.29 is now the "base" AEC optical density for
the film/screen being calibrated.
