Abstract: The invention provides a remote flashgun incorporating a xenon flash bulb for use with a mobile device comprising an internal camera that enables the user to take improved photographs in low light conditions. A plastic case is used to hold the flashgun and mobile device in close proximity. An application running on the mobile device communicates with the flashgun to provide information on the required total flash light output and timing to synchronize with the mobile device capturing an image or photograph. The invention further enables the user to take photographs of high speed events, such as a balloon bursting. The flashgun is configured with an integrated microphone to provide a trigger signal to operate the xenon bulb at a time suitable to illuminate the high speed event. The application operates the camera to take continuous images and captures the image when the flash bulb was operated.
