Picture Size - CEI Color Six Operator's Manual

Note–Field curvature may be observed when
attempting to focus the center and edges of
the image simultaneously. This can be mini-
mized by closing the iris slightly, which will
improve the depth of focus.

Picture Size

The image size adjustment control for the CEI Custom
Universal Optical System is located on the lens barrel. To
adjust picture size,
1. Locate the control ring closest to the film camera on the lens
barrel.
2. Loosen the locking set screw to free the small handle on the
control ring.
3. Rotate the ring slowly, observing the change in image size.
4. Periodically refocus the image to determine if the image size
is correct.
5. When size and focus are both correct, gently tighten the set
screws.
Note–The Color Six has the capability of
zooming the image about 2:1 electronically, in
addition to the lens size adjustment, so the
image size can be mechanically set a bit
smaller and electronically zoomed to the ex-
act size necessary in a later step.
