Canon Bulb Exposures

Bulb Exposures

When bulb is set, the shutter stays open while you hold down the shutter button fully, 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.

The exposure continues as long as you hold down the shutter button.

Since bulb exposures will have more noise than usual, the image will look rough or grainy.

Bulb exposures may result in grainy images due to picture noise. If C.Fn- 02 [Long exp. noise reduction] is set to [1: Auto noise reduction] or [2: On] (p.151), noise can be reduced.

For bulb exposures, using Remote Switch RS-80N3 or Timer Remote Controller TC-80N3 (both optional) is recommended.
