can use any shutter speed and the flash will adjust (pulse)
to match lighting needs. With the larger Speedlights, you’ll
need to learn how to balance ambient light with light from
the flash when using shutter speeds higher than 1/250 s.
Just remember that your flash unit’s range will be seriously
reduced at higher shutter speeds.
Flash Shutter Speed
Custom setting e2 (D300S and D300)
(User’s Manual – D300S page 282; D300 page 291)
Flash shutter speed controls the minimum shutter speed your
camera can use in various flash modes. You can select
between 30 seconds (30 s) and 1/60 s.
Let’s consider each of the modes and the minimum shutter
speed for it:
▪ Front-curtain sync, Rear-curtain sync, or Red-eye
reduction – In Programmed auto (P) mode or Aperture
priority auto (A) mode, the slowest shutter speed can be
selected from the range of 1/60 s to 30 seconds (see
Figure 4-49). Shutter priority (S) mode and Manual (M)
mode cause the camera to ignore Flash shutter speed,
and the slowest shutter speed is 30 seconds (30 s).
▪ Slow sync, Red-eye reduction with slow sync, or Slow
rear-curtain sync – These three modes ignore Flash
shutter speed, and the slowest shutter speed is 30
seconds.
