F: Bulb Exposures

When bulb is set, the shutter stays open while you hold down the shutter
button completely, and closes when you let go of the shutter button. This
is called bulb exposure. Use bulb exposures for night scenes, fireworks,
the heavens, and other subjects requiring long exposures.
Elapsed exposure time
Since bulb exposures produce more noise than usual, the image might
look rough or grainy.
When [8C.Fn II -1: Long exp. noise reduction] is set to [1: Auto] or
[2: On], noise generated by the bulb exposure can be reduced (p.176).
For bulb exposures, using the Remote Switch RS-80N3 or Timer Remote
Controller TC-80N3 (both sold separately) is recommended.
Bulb exposures can also be taken with a remote controller (sold separately, p.102).
When you press the remote controller's transmit button, the bulb exposure will start
immediately or 2 sec. later. Press the button again to stop the bulb exposure.
