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 2-9).
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
(c) To adjust the camera to the reduction or enlargement, set
the slow-fast 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 2-7). To make
fine adjustments, set the slow-fast 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 2-11). 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 f-stop and timer.
Using the exposure chart
attached to the camera, find the f-stop setting for the print material
you selected (figure 2-10). Then check the lens f-stop-setting (figure
2-8) and set it to the required setting for the print material you
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 2-7).
(5) Positioning the print material. Insert your hands through the
compartment (figure 2-11), 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
