Note: bulb support is not yet available in the Arsenal app. It will be coming soon on cameras that enable that functionality through their API. Thanks for your patience!
Bulb is a camera setting that allows the shutter to be held open indefinitely for long exposures. Using bulb requires your camera to support wireless bulb control. You'll also need a tripod -- unless you're getting experimental!
Bulb support with Arsenal
Arsenal will control bulb exposures with most of the camera models we support. However, several of our supported cameras do not allow bulb control over USB. In this situation, Arsenal will be limited to shooting at the camera's slowest shutter speed.
To use bulb with Arsenal, open the app, select Smart or Manual Mode, and tap on the trigger mode to the left of the shutter button ("tap shot" by default). Select either Bulb Hold or Bulb Tap.
To use Bulb Hold, select Bulb Hold as your shutter setting. When you're ready to take a photo, press and hold your finger on the app's shutter button. The shutter will stay open until you lift your finger off the button.
You don't need to press hard; simply keep your finger in contact with the button on the screen.
To use Bulb Tap, select Bulb Tap as your shutter setting. When you're ready to take a photo, tap the app's shutter button. The shutter will open. To end the exposure, tap the shutter button a second time.
When you're done using bulb, be sure to set your shutter setting back to Tap Shot so it will be ready for action.
