f. Camera bed. The camera bed includes two tubular guide rails (figure
1) with an end block at each end. Wire-rope pulleys are secured to brackets
within the end blocks. Two connecting bars between the tubular guide rails
provide additional rigidity for the camera bed.
g. Easel.
The easel (figures 1 and 3) is hinge-mounted on the front
end and includes a blasted glass secured within the easel frame.
Five
interlocking photographic masks [(1) below] are supplied to hold-copy to the
glass frame. Both the glass frame and the masks use clips to secure copy,
or the next smaller mask, to the easel. A calibrated mounting plate [(2)
below], mounted on a sponge rubber padded mounting board, and two glass
plates are also part of the easel.
(1) Masks. Five standard size interlocking masks (figure 3), ranging
in masks size from 3 1/4" x 4" through 11" x 14", are used to exclude
extraneous light from the camera lens. The large mask can be used by itself
to frame an object on the easel. However, when a smaller mask is used, it
must be mounted within the next largest mask. Thus, when the smallest mask
(3 1/4" x 4") is used, the largest mask must be first mounted on the easel.
(2) Mounting plate. The mounting plate (figures 1 and 3) is used to
provide copy support on the easel. The mounting plate has a white imprinted
scale, calibrated in inches, and a border imprinted for 8 1/2" x 11" and 8
1/2" x 14" sheets.
