Photographing to conform to purposes
Multiple exposure mechanism
While pressing the lock release button “A”, move the
lever in the arrow direction to the multiple exposure
position.
It does not matter if the changeover to multiple exposure
is made before or after the first exposure. Once
changed, the shutter is released and wind-up lever is
cocked, but the film counter does not advance.
•
When taking multiple exposures of subjects with
the same brightness, exposure compensation is
necessary. When taking multiple exposures of
subjects with different brightness, take an
exposure of the darker subject first. Then follow
with an exposure of the lighter subject.
•
After finishing multiple exposure photographing,
be sure to return the lever to normal position.
Infrared Photography
When using infrared film, it is necessary to make a
focusing adjustment in order to achieve accurate focus.
This is because the focus position of the image deviates
from normal since the infrared ray wavelength is longer.
After focusing in the usual manner, check the distance
on the distance scale that is aligned with the center
reference mark “A” of the lens. Make the focusing
adjustment by turning the focusing ring in the direction of
the arrow in the accompanying photograph so that the
distance just observed is aligned with the infrared mark.
*When using infrared film, be sure to read the instructions with the film.
