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.
