Long Time-Exposures
Close the viewfinder eyepiece shutter to prevent light entering via
the viewfinder from appearing in the photograph or interfering
with exposure (
0 114). Nikon recommends using a fully charged
battery or an optional AC adapter and power connector to prevent
loss of power while the shutter is open. Note that noise (bright
spots, randomly-spaced bright pixels or fog) may be present in
long exposures; before shooting, choose On for the Long
exposure NR option in the shooting menu (
0 308).
