Bulb Exposures

closes when you release it. Bulb exposures are useful for the long exposures required for night
scenes, fireworks, etc.

The elapsed exposure time displayed on the LCD panel is only counted up to
999 seconds. For accurate exposure time, check the information display for the
exposed image. (->-104)
Long exposures exceeding 1 second result In increased noise introduced into
the image, and reduce the quality of the image.
The Remote Switch RS-80N3 (sold separately), or Timer Remote Controller TC-80N3
(sold separately) can be used to eliminate the need to hold down the shutter button.
C.Fn In long exposures, some degree of noise can enter the exposed image. You can use
the Long exposure noise reduction function to reduce the noise. (C.Fn-1->-124)
