Long Time-Exposures
Close the viewfinder eyepiece shutter to prevent the photograph
being affected by light entering via the viewfinder (
0 120). 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. Bright spots
and fog can be reduced by choosing On for Long exposure NR in
the photo shooting menu (
0 294).
