Sometimes the ambient light level is too low for successful for photography, or it’s the ‘wrong’ kind of light. This is where photographers turn to flash (or ‘strobe’, if you’re in the US). Flash works by emitting a very short, very powerful burst of light. Energy is stored in a capacitor in the flash head […]
Flash power is normally handled automatically by the camera, but you can increase or reduce the flash power with the flash compensation option – it’s just like using the exposure compensation option with automatic exposure.
