❚❚ Long Time-Exposures (M Mode Only)
Select a shutter speed of “Bulb” for long
time-exposures of moving lights, the
stars, night scenery, or fireworks. The
shutter remains open while the shutter-
release button is held down. To prevent
blur, use a tripod.
1 Ready the camera.
Mount the camera on a tripod or place it on a stable, level sur-
face. To prevent loss of power before the exposure is com-
plete, use a fully charged EN-EL20 battery or an optional
EH-5b AC adapter and EP-5C power connector. Note that
noise (bright spots, randomly-spaced bright pixels, or fog)
may be present in long exposures; before shooting, choose
On for Long exposure NR in the shooting menu (
0 128).
A The Exposure Indicator
When shutter speeds other than “Bulb” are selected, the exposure indi-
cator shows whether the photograph would be under- or over-
exposed at current settings.
