1-3. The largest camera
available in the Army is the 8x10-inch copy camera KS-
7A. Due to its size and
being nonportable, it is used in a fixed location such
as a post photographic
laboratory facility, or the Training and Audiovisual
Support Center (TASC).
The 8x10-inch format camera can provide the following
color and B/W products:
8x10 negatives.
8x10 transparencies.
4x5 negatives.
4x5 transparencies.
Polaroid prints.
a. It is primarily used for copying large flat items, such as large
charts and naps. It can produce 1:1 negatives or transparencies, and
enlarge small areas.
This camera has the capability of reducing or
enlarging copy by 4 diameters.
This is all possible because the
camera's focusing capability extends from 15 to 60 inches.
b. The camera consists of a front frame which holds the lens board, front
and rear bellows, rear frame which holds the reversible 8x10-inch
ground glass and 4x5-inch ground glass for focusing.
Both the front
and rear frames can be moved manually to focus.
c. Figure 1-3 shows an 8x10 camera set, Still Picture KS-7A, with
components.
This camera is most commonly used for copy work in the
military today; but, here again, it all depends on the final product,
whether it is to be a 35mm transparency, an 11x14-line copy, or large
color print. The size of the original and final product desired will
dictate the format you should use.
d. We will cover the functions of the KS-7A camera later in this lesson
when we talk about copying large objects for large reproduction.
