Long Time-Exposures
Shutter speeds of “bulb” and “--” can be used for long time-exposure photographs of mov-
ing lights, the stars, night scenery, or fireworks. To prevent blurring caused by camera shake,
use a tripod or an optional remote control ( 33, 103).
To prevent loss of power before the exposure is complete, use a fully charged battery or an
optional AC adapter. Note that noise may be present in long exposures; before shooting,
choose On for the Noise reduction option in the shooting menu.
