❚❚Long Time-Exposures (M Mode Only)

Shutter speeds of “

A” and “&” can be used for long time-exposure

photographs of moving lights, the stars, night scenery, or fireworks. To prevent
blurring caused by camera shake, use a tripod and an optional remote control
(pg. 241) or remote cord (pg. 241).

Ready 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 battery or an
optional AC adapter. Note that noise may be present in long exposures; before
shooting, choose On for the Long exp. NR option in the shooting menu
(pg. 165). If you are using an optional remote cord, attach it to the camera.
