4. The display screen now indicates suggested changes for your filter pack.
These numbers are changes (indicated by the Greek letter
∆
) and should
be added to the filter pack used for exposing this internegative. Press key

(

values.

5. The absolute values are the addition of your starting filter pack (entered
earlier) and changed values. These values are adjusted to remove any
neutral density. Therefore, one of these values (usually cyan) is always
zero. These values constitute your new filter pack which should be used
for subsequent exposures. Press key
lll
(exp) to display the suggested
exposure.

NOTE:
Any neutral density adjustments to the filter pack affect exposure as
well. To avoid reciprocity problems, exposure time is held within ½ stop of
your starting exposure time. This sometimes causes an aperture change if the
calculated exposure time adjustment is greater than ½ stop.

7. Measure another internegative. The entire procedure described is
repeated, except that the exposure and filter pack values just viewed are
used as the starting point.
