a: Manual Exposure I Using the Built-in Flash To obtain a correct flash exposure, the flash output will be set automatically (autoflash exposure) to match the manually-set aperture. The flash sync speed can be set from 1/200 sec. to 30 sec. and bulb. BULB: Bulb Exposures Elapsed exposure time 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. In step 2 on the preceding page, turn the dial to the left to set . The elapsed exposure time will be displayed on the LCD monitor. During bulb exposures, do not point the lens toward the sun. The sun's heat can damage the camera's internal components. Since bulb exposures produce more noise than usual, the image might look a little grainy. You can reduce the noise due to long exposures by setting [3: Long exp. noise reduction] to [1: Auto] or [2: On] in the [7 Custom Functions (C.Fn)] (p.219). For bulb exposures, using a tripod and Remote Switch (sold separately, p.229) is recommended. 98
