How to use the bulb setting on the EOS Digital Rebel XT.

Solution

When bulb is set, the shutter stays open while you hold down the shutter button fully, and closes when you let go of the shutter button. This is called bulb exposure. Use bulb exposures for night scenes, fireworks, the heavens, and other subjects requiring long exposures.

- 1. Set the Mode Dial <M>.
2. Set the shutter speed to "".
  • Look at the LCD panel and turn the <> dial to select "".
  • The next setting after "" is "".
3. Set the desired aperture value.
  • Hold down the <AV > button and turn the <> dial.
4. Take the picture.
  • Press the shutter button completely.
  • The elapsed exposure time will be displayed on the LCD panel. (Displays 1 sec. to 999 sec.)
  • The exposure continues as long as you hold down the shutter button.
Since bulb exposures may have more noise than usual, the image may look rough or grainy.
  • Bulb exposures may result in grainy images due to picture noise. You can reduce noise by setting C.Fn-2 [Long exposure noise reduction] to [1: On].
  • For bulb exposures, using Remote Switch RS-60E3 (optional) is recommended.
  • Remote Controller RC-1/RC-5 (optional) can also be used for bulb exposures. When you press the transmit button, the exposure will start 2 sec. later. To stop the exposure, press the button again.
