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.
