Digital Still Camera DSC-RX100M3


You can shoot a trailing image of the movement of a subject with long exposure.

BULB is suitable for shooting trails of light, such as fireworks.

  1. Set the mode dial to M (Manual Exposure).
  2. Press the bottom side of the control wheel to select the shutter speed, then turn the control wheel counterclockwise until [BULB] is indicated.
  3. Press the bottom side of the control wheel to select the aperture value (F value), and turn the control wheel to set the value.
  4. Press the shutter button halfway down to adjust the focus.
  5. Press and hold the shutter button for the duration of the shooting.
    As long as the shutter button is pressed, the shutter remains open.


  • Since the shutter speed becomes slow and the camera-shake tends to occur more easily, it is recommended that you use a tripod.
  • The longer the exposure time, the more noise will be visible on the image.
  • After shooting, noise reduction will be done for the same amount of time that the shutter was open. However, you cannot shoot any more while noise reduction is in progress.
  • You cannot set the shutter speed to [BULB] in the following situations:
    • When the [Smile Shutter] function is activated.
    • When the [Auto HDR] function is activated.
    • When [Picture Effect] is set to [HDR Painting] or [Rich-tone Mono.].
    • When the [Multi Frame NR] function is activated.
    • When the [Drive Mode] function is set to [Cont. Shooting], [Cont. Bracket], [Spd Priority Cont.] or [Self-timer(Cont)].
    If you use the above functions when the shutter speed is set to [BULB], the shutter speed is temporarily set to 30 seconds.


  • Images shot in [BULB] mode tend to be blurry. We recommend that you use a tripod or a remote commander (sold separately) that has a shutter button lock function.
