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. 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 and distortion may be present in long
exposures; before shooting, choose [On] for
the [Long exp. NR] option in the shooting
menu (pg. 300).
