❚❚Long Time-Exposures (M Mode Only)

At a shutter speed of “bulb,” the shutter remains open while the shutter-release button is held down. This can be used for long time-exposure photographs of moving lights, the stars, night scenery, or fireworks. A tripod or optional MC-DC2 remote cord (0 177) is recommended to prevent blur.

Length of exposure: 35 s

Aperture: f/25

1Ready the camera.

Mount the camera on a tripod or place it on a stable, level surface. To prevent loss of power before the exposure is complete, use a fully charged EN-EL14 battery or an optional EH-5a AC adapter and EP-5A power connector. Note that noise (randomly-spaced bright pixels or fog) may be present in long exposures; before shooting, choose On for the Noise reduction option in the shooting menu (0 134).
