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.

Since bulb exposures have more noise than usual, the image may 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.156)

 

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