BASIC OPERATION
K Making Multiple Exposures
Exposing
the same frame of film with two or more
images is an exciting technique used by many
photographers to create dream-Ii ke scenes, abstract
designs,
motion studies, or humorous pictures . Your
imagination is the only limiting factor in this creative
process, because Canon
has made multiple exposure
photography so easy to perform with the E F camera.
A
multiple exposure button is located in the center
of . the ON/OFF switch. After making your first
exposure, hold in this button with your left thumb
while operating thewinding lever in the normal way.
The movement of the film transport sprocket is
stopped, while the winding lever recocks the shutter .
Now you are ready for your next shot which will be
in
perfect registration directly on top of the first
shot. This process may be repeated any number of
times, and the frame counter is stopped until the
film is actually advanced to the next frame .

• The multiple ' exposure button need not be de-
pressed
during the entire winding operation, but
only needs to be held in at the beginning of the
stroke .
• I n
multiple exposure photography, exposures on
the same frame of film are additive . In the AE mode
of operation, the Canon EF automatically deter-
mines
the proper exposure needed for a. single frame .
When
making multiple exposures, less exposure must
be given to each shot . One simple way to do this is
to reset the ASA ring to a higher setting, which will
fool the camera into decreas'ing the exposure read-
ing.
Multiply the normal ASA of the film by 2 for a
double exposure, by 3 for a triple exposure, by 4 for
a quadruple exposure, and so forth. However, when
making
mUltiple exposures of night lights or a
subject against a
black background, do not reset the
ASA ring, because the black areas in the scene will
become overexposed.
