Depends on the ambient light.  If you take a picture in total darkness and
rely only on the flash, you won't see any difference, the flash exposure is
affected only by the aperture. The shutter speed will affect things like
subject movement and exposure for the background lighting.

Hi everyone,

A minor question: which settings for the aperture should I use on a M3 if I
want to shoot at shutter speeds less than the 1/50 flash sync speed. For
example, using ASA 400 speed film and the subject is 6 feet, the flash guide
suggests f16 at the regular flash sync of 1/50. What should I do if I want
to use flash at 1/4 sec. speed? Or 1 sec. speed?

Thanks for your input.

Alfie
