Installation
4. Modifying the ARRIFLEX 435
for Singleframe Takes
First, check that a 26-pin socket is visible on the right lower
side of the camera, as this is necessary for singleframe takes.
If there is no socket, the camera must be modified by an
authorised ARRI service center.
4.1 General
Due to the design of mirror-reflex film cameras, stray light
may pass around the mirror shutter onto the film when the
camera is not running. For normal film shots this is not a
problem, as the affected images fall into the camera run-
up, which is usually not used anyway. On singleframe shots
however, the stray light which during interval time can fall
onto the film around the mirror shutter can affect the quality
of the exposed singleframes.
The ARRI Integrated Capping Shutter covers the film during
the interval time with a thin metal plate. The metal plate is
pushed into the film gate after exposure. Before the next
exposure the plate is removed.
