MULTIPLE EXPOSURE
By tripping the shutter several times on the same
frame, multiple images are produced on the same
frame.
This is how to do:
After the first exposure is ended, erect the re-
wind crank and turn it clockwise as far as it
will go to take up film slack.
While holding both the rewind knob and rewind
button with your fingers to prevent them from
moving, wind the film advance lever.
In fact, the film is not wound and the shutter is
cocked by this operation.
Press the shutter release as you would do normal-
ly, and double exposure will occur.
By repeating the steps and , the frame
will be exposed as many times as you want. How-
ever, the frame counter advances each time the
shutter release is pressed.
After ending the multiple exposure, put the
front lens cap on and make a blind shot.
Note: The frame may shift slightly.
INFRARED PHOTOGRAPHY
When shooting infrared pictures with infrared film
and a red filter, the point of focus will slightly dif-
fer if you focus visually. The amount of shift varies
with the lens and a red line or red dot is marked on
the lens' depth of field scale to compensate for it.
First, focus the lens without a red filter on as you
would do normally. Next, read that distance on the
distance scale and shift it opposite the infrared
mark, then put on a red filter and shoot. (The above
picture was taken with the distance at infinity.)
