Pentax MX - Pentax MX Multiple Exposure Guide

MULTIPLE EXPOSURE
For deliberate multiple exposures, make the first
exposure in the normal way. Then tighten the
film by turning the rewind knob , and keep
hold of the rewind knob. Depress the film rewind
release button and advance the rapid-wind
lever. This cocks the shutter without advancing
the film. Finally release the shutter to make the
second exposure. Then make one blank exposure,
before taking the next picture, to avoid overlapping.
As the exposure counter continues to function
each time the shutter is cocked, a double
exposure will be counted as two frames.
