fireworks and other subjects requiring
long exposures.

<_ > dial to the left to set <BULB>.
The elapsed exposure time will be
displayed on the LCD monitor.
_ During the bulb exposure, do not point the lens toward the sun. The
sun's heat can damage the camera's internal components.
Since bulb exposures produce more noise than usual, the image may
look a little grainy.
When [1_13:Long exp. noise reduction] is set to [Auto] or [Enable],
norsegenerated by the long exposure can be reduced (p.125).
