MULTIPLE EXPOSURES
INFRARED PHOTOGRAPHY
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 rewind
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. However,
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.
When shooting infrared pictures with infrared film
and a red filter, the point of focus will slightly differ 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 shows
the distance at infinity.)
