[Illustration: THE COPYING AND ENLARGING AND REDUCING CAMERA. FIG.
13.]
Copying constitutes a large portion of the business of every
gallery, and a camera for that purpose is almost indispensable, as
the portrait camera is entirely unfitted for a major portion of the
copying work that comes.
The copying camera requires no swing back, but does require great
length of bellows and bed, which has often to be supplemented by the
cone when a very small picture is to be enlarged to a great size.
A special form of copying camera is adapted to enlarging and
reducing negatives, and for making transparencies. This form, Fig.
14, can be so arranged as to render it possible to remove the lens
from the position as seen in Fig. 14 to the front, so that the two
[p111] forms, Figs. 13 and 14, might be combined in one for
copying and making transparencies.
