CHAPTER 16TRICK WORKRICK AND STUNT PHOTOGRAPHY with the stereo camera is di-
T vided into two parts; that which is conventional camera
trickery applied to the stereo camera, and that which depends
wholly upon stereo principles and has no counterpart in planar
photography. Naturally there are some tricks which are more or
less borderline, as for example the false impression given by using
an abnormal camera angle. This is common practice in planar
work, but when so used it lacks the unreal appearance which
makes it a part of trick work.
DOUBLE ExPosum.-This is done too often by accident to be
unfamiliar to the stereographer, but the accidental shot is merely
confusion while the planned double exposure can be made highly
effective.
There are two kinds of straight double exposure. The simplest

close-up type of supplementary.
