How to use BULB mode

For long exposure photography.

BULB mode allows you to take long exposures beyond the typical 30-second limit of most cameras. This is essential for astrophotography, light painting, and creative night photography.

To use BULB mode with Shutter:

  1. Set your camera's exposure mode to BULB (sometimes labeled "B" on the mode dial)
  2. Connect your camera to Shutter
  3. Use the BULB control in the app to start and stop the exposure

Tip: For very long exposures, consider using a tripod and remote trigger to minimize camera shake.
