you may lose a frame on the fi lm unless you make sure that the shutter is cocked before you
attach the motor winder. To remove the winder, remove the lens. Holding the winder fi rmly,
press the detaching lever and keep it pressed while turning the winder counterclockwise.
The lens must be removed for attaching and detaching the winder.
Motor Operation
The motor winder can be used for single exposures (S) at any shutter speed but at shutter
speeds of 1/8 second and longer, keep the release depressed until you hear the lens shutter
closing. In sequence photography (C), the shutter speed must be 1/8 second or shorter (1/15
second or shorter in cold temperatures). For multiple exposures set the mode selector to M.
The motor makes the exposure but does not advance the fi lm. Insert the darkslide, remove
the magazine, and switch the mode selector from M to S (or C) to recock the shutter.
Re-attach the fi lm magazine and remove the darkslide. Set the mode selector to L (lock) to
prevent accidental exposures when not in use (see Figure 9-4). Double and multiple expo-
sures in digital imaging are made the same way but you need not worry about advancing the
fi lm accidentally.
Figure 9-4 The winder operating controls. The release and mode selector have these settings: RC
(remote), L (lock), S (single pictures), C (sequences), and M (multiple exposures).
If the motor does not operate the camera, check whether a darkslide might be inserted
and whether the frame counter in the fi lm magazine indicates that you are at the end of the
fi lm. Also check that the mode selector is not set to L or RC, and, of course, check the condi-
tion of the batteries and be sure that they have been inserted properly.
Remote Operation
A camera equipped with a motor winder can be remote-released in the S (single), C (continu-
ous), and M (multi) mode by using a 10-foot (3 m) accessory release cable connected to the
motor winder or by using the wireless infrared remote control. With the mode selector set to
RC, the compact IR remote release (see Figure 9-5) can operate the camera from up to 33 feet
(10 m) from any direction because the motor winder has IR sensors at the front and rear.
