MULTIPLE PURPOSE
Intentional multiple exposure (two or more exposures on the
same frame) for creative effects are easy with the FM. First,
make the initial exposure. Then, slide the multi-exposure
button as far as it will go, and hold it while you stroke the
film-advance lever; repeat this procedure for each additional
exposure on the same frame. When you have achieved the
desired number of exposures on the same frame, release the
button and stroke the film advance lever once more. Note
that during multiple exposure operation, both the camera’s
shutter speed and the lens aperture can be freely changed to
any setting; also, the frame counter will remain at the same
setting until the multi-exposure button is released—a conve-
nient way of confirming that multiple exposure operation is
proceeding properly.
