a: Manual Exposure
114
To obtain the correct flash exposure on the main subject, the flash
output will be set automatically (autoflash) to match the manually-set
aperture. The shutter speed can be set from 1/200 sec. to 30 sec. or to
bulb.
A bulb exposure keeps the shutter open
for as long as you hold down the shutter
button. It can be used to shoot fireworks
and other subjects requiring long
exposures.
In step 3 on the preceding page, turn the
<6> dial to the left to set <BULB>.
The elapsed exposure time will be
displayed on the LCD monitor.

BULB: Bulb Exposures
Elapsed exposure time
Do not point the camera toward an intense light source, such as the sun
or an intense artificial light source. Doing so may damage the image
sensor or the camera’s internal components.
Since long bulb exposures produce more noise than usual, the image
may look slightly grainy.
You can reduce the noise due to long exposures by setting [4: Long exp.
noise reduction] under [53: Custom Functions (C.Fn)] to [1: Auto] or
[2: On] (p.262).
If ISO Auto is set for a bulb exposure, the ISO speed will be fixed at ISO
800 (p.94).
For bulb exposures, using a tripod and a remote switch (sold separately,
p.271) is recommended.
