Bulb Exposures - Canon EOS-1D C Instruction Manual

Bulb Exposures

When bulb shooting is set, the shutter stays open as long as you hold
down the shutter button completely, and closes when you let go of the
shutter button. Use bulb exposures for night scenes, fireworks, the
heavens, and other subjects requiring long exposures.
(1)
Long exposures produce more noise than usual.
ISO speed is fixed to ISO 400 when ISO Auto is set (p.129).
When [z2: Long exp. noise reduction] is set to [Auto] or [Enable],
noise generated by the long exposure can be reduced (p.152).
For bulb exposures, using a tripod and Remote Switch RS-80N3 (sold
separately) or Timer Remote Controller TC-80N3 (sold separately) is
recommended (p.183).
