Bulb Exposures

In step 2, turn the <6> dial left to set <BULB>. A bulb exposure keeps the shutter open for as long as you hold down the shutter button. It can be used to photograph fireworks, etc. If you press the <B> button during the bulb exposure, the elapsed exposure time will be displayed.

Since bulb exposures produce more noise than usual, the image will look rough or grainy. You can reduce this noise by setting the [bCustom Functions (C.Fn)] menu’s [Long exp. noise reduction] (p.103) to [Auto] or [On].
