current size of the copy on the inner scale with the required size of
the print on the outer scale. The percent of change then appears in the
percentage of original size window of the scaling wheel (figure 29).
This is the setting used for the camera. For example, the size of the
copy is 8 by 12 inches, and the print must fill an area 10 by 15 inches.
After you have aligned the two scales, the percentage window reads 125
(enlargement).
(c) To adjust the camera to the reduction or enlargement, set
the slowfast switch in the sizing section of the control panel to the
fast position. Then press the enlarge or reduce switch until the
scale's pointer aligns with the required reproduction size (figure 27).
To make fine adjustments, set the slowfast switch to the slow position,
and press the enlarge or reduce switch until reaching the desired
setting.
(3) Positioning split platen. After you set the correct reduction
or enlargement, lift the red viewer lid and ensure the light selector is
in the main light position. Then fold down the split platen so it
covers the image area (figure 211). Now press the view button and
check the image, ensuring it centers correctly on the split platen
marks. If the copy is not correctly centered, you must recenter it on
the copyboard. After you have the copy centered on the split platen,
unfold the split platen and close the red viewing lid.
(4) Setting the fstop and timer. Using the exposure chart
attached to the camera, find the fstop setting for the print material
you selected (figure 210). Then check the lens fstopsetting (figure
28) and set it to the required setting for the print material you
selected.
To set the timer, again refer to the exposure chart attached to the
camera and find the required exposure time and processor speed for the
print material you have selected. Then set the timer to the required
time and the processor to the required speed (figure 27).
(5) Positioning the print material. Insert your hands through the
compartment (figure 211), remove the selected photo material, and trim
it to size. Place any remaining photo material back in the storage
compartment and close the lid. Remember, the smallest size photo
material the camera accommodates without jamming is 2 1/2 by 7 inches.
When using any type of film or exposing paper for more than 45 seconds,
you must use a black cardboard backup card, cut to the same size as the
selected material.
