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. The elapsed exposure time
will be displayed on the LCD monitor.
Since bulb exposures produce more noise than usual, the image will look
rough or grainy. You can reduce this noise by setting the [7 Custom
Functions (C.Fn)] menu's [Long exp. noise reduction] (p.155) to [1:
Auto] or [2: On].
The Auto Lighting Optimizer (p.156) will not work.
