Bulb Exposures. Canon EOS 5DS, EOS 5DS R

F

: Bulb Exposures

In this mode, the shutter stays open as long as 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.

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.

Long exposures produce more noise than usual.

If Auto ISO is set, the ISO speed will be ISO 400 (p.160).

For a bulb exposure, if you use both the self-timer and mirror lockup instead of the bulb timer, keep pressing the shutter button completely

(self-timer delay time + bulb exposure time). If you let go of the shutter button during the self-timer countdown, there will be a shutter-release sound, but no picture will be taken. If you use the bulb timer under the same shooting conditions, you need not hold down the shutter button completely.

With [ z 3: Long exp. noise reduction ], you can reduce the noise

generated during long exposures (p.185).

For bulb exposures, using a tripod and bulb timer is recommended.

Using mirror lockup (p.234) with bulb exposures is also possible.

You can also shoot bulb exposures by using Remote Switch RS-80N3 or

Timer Remote Controller TC-80N3 (both sold separately, p.237).

You can also use Remote Controller RC-6 (sold separately, p.237) for

bulb exposures. When you press the remote controller’s transmit button, the bulb exposure will start immediately or 2 sec. later. Press the button again to stop the bulb exposure.
