Long Time-Exposures
At a shutter speed of A, the shutter will remain open while the
shutter-release button is held down. Use for long time-exposure
photographs of moving lights, the stars, night scenery, or
fireworks. A tripod and optional remote cord (
0 376) are
recommended to prevent blur.

Long Time-Exposures
Close the viewfinder eyepiece shutter to prevent light entering via
the viewfinder from appearing in the photograph or interfering
with exposure. Nikon recommends using a fully-charged EN-EL4a
battery or an optional EH-6 AC adapter to prevent loss of power
while the shutter is open. Note that noise (randomly-spaced bright
pixels or fog) may be present in long exposures; before shooting,
choose On for the Long exp. NR option in the shooting menu
(
0 291).
