The general rule is to use 1/n the exposure for each shot of an n-fold exposure. If n is 2, that means close the lens 1 stop, or double the shutter speed, or double the ASA/ISO setting. For programmed automation, the only alternatives are the film-speed change and the exposure compensation knob (set that toward UNDEREXPOSURE). Remember that `n' is linear and `stops' are logarithmic. Remember to return everything to normal when finished. Sometimes you may want to break the above rules for esthetic reasons. -- Gene E. Bloch (...!nsc!voder!gino) Mr Humility
