How to set long (bulb) exposures on the EOS 1D Mk III

Solution

When bulb is set, the shutter stays open while you hold down the shutter button completely, 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.

Select "buLb".

  • Press the <MODE> button and turn the </> dial to select "buLb".

Set the desired aperture.

  • While looking at the top LCD panel, turn the </> dial.

Take the picture.

  • Press the shutter button completely.
  • The elapsed exposure time will be displayed on the top LCD panel. 1: min. 2: sec. 3: hour
  • Since bulb exposures produce more noise than usual, the image will look rough or grainy.
  • For bulb exposures, using Remote Switch RS-80N3 or Timer Remote Controller TC-80N3 ( optional) is recommended.
  • When C.Fn II -1 [Long exp. noise reduction] is set to [1:Auto] or [2:On], noise generated by the bulb exposure can be reduced.
