• Stroboscopic flash is most effective with a highly
reflective subject against a dark background.
• Use of a tripod, a remote switch, and an external power
source is recommended.
• A flash output of 1/1 or 1/2 cannot be set for
stroboscopic flash.
• Stroboscopic flash can be used with bulb mode on the
camera.
