Some digital cameras fire one or more measuring preflashes a fraction of a second before flash ex- posure. Normally, these measuring preflashes can- not be deactivated on the camera because they do influence, for example, the flash exposure. More- over, a preflash function can be activated on many cameras to diminish the “red eye effect”.

Please note that the working range is diminished outdoors and with bright ambient light. Avoid exposing the sensor to direct sunlight!
