SB-25 Feature Comparison: Flash Operations Available with Your Camera
When used with any Nikon SLR, the SB-25 is capable of
strobo-effect multiple flash exposure at up to 160 flash per
frame; it also allows control of the amount of flash light out-
put. Operation becomes simple once you learn how to
match the number and speed of flash to your desired shut-
ter speed.
For details, see “Repeating Flash
Mode — For
Multiple Exposure,” pages 90 to 95.
Red-Eye Reduction Control
“Red eye” effect occurs in flash photography when flash
pictures are taken in dim surroundings where the subject’s
eye pupils will be dilated (opened very wide). Light from the
camera’s flash reflects off the interior of the eye through the
wide-open pupil and back into the camera’s lens; the result
in the photo appears as bright red eyes.
The SB-25 fires three consecutive flash prior to the main
flash. This causes the subject’s pupils to constrict (become
smaller), reducing the appearance of red-eye.
The F90-Series/N90 offers this exclusive Red-Eye
Reduction Control to control preflash, for use in any flash
mode, except Repeating Flash mode. For more details and
setting operation, see page 104, and the camera’s instruc-
tion manual.
Red-eye effect can also be controlled by the angle at
which light strikes the subject and is reflected back to the
camera’s lens. For further details, see “Red Eye,” page 134.
Repeating flash mode offers “strobo effect,” multiple exposure on a
single frame.
