MULTI (STROBOSCOPIC) MODE
Usage is similar to Remote Manual and On-flash Manual. Stroboscopic mode is particularly effective with a highly-
reflective subject against a dark background. Consider using a tripod, remote switch and external battery pack.
 Set Flash Mode to Multi.
 Set desired Flash output, Frequency and Flash count, as provided by the camera.
 Flash Count x Hz = minimum shutter duration.
 Limit rapid use and allow at least 15 minutes rest between frequent bursts.
 E-TTL Flashes do not emit a pre-flash
