!!!DESIGNED FOR USE WITH SAMSUNG GALAXY S3 ONLY!!!
This Flash Meter allows the user to set correct aperture for proper exposure in the given lighting condition. It measures ambient light and calculates aperture using the chosen ISO and shutter speed values. It has three modes: Cordless Flash, Ambient Light, and Exposure Value.
In Cordless Flash mode, a cordless flash can be used to trigger the sensor. The flash brightness is used to determine what aperture to use for proper exposure.
In Ambient Light mode, the ambient light is used to determine what aperture to use for proper exposure.
In Exposure Value mode, the ambient light is converted to EV values for the ISO value chosen by the user.
