Repeating Flash
Mode — For Multiple Exposure
For multiple flash exposures on a single frame, use the
SB-25 in the mode. The flash can be fired up to to 160
times on one frame, and if used in conjunction with the
camera body’s multiple exposure control, many more flash
can be achieved on the same frame.
When making multiple exposures, there are many factors
to consider. You may want to experiment before making the
final exposure.
Before proceeding:
✗ ATTACH SPEEDLIGHT TO CAMERA.
✗ TURN ON BOTH SPEEDLIGHT AND CAMERA.
✗ USE MANUAL EXPOSURE MODE.
✗ USE SINGLE-SERVO AUTOFOCUS (S or A) OR MANU-
AL FOCUS (M).
✗ USE SINGLE-FRAME SHOOTING (S) FILM ADVANCE
MODE.
