Fill flash is a technique photographers use to brighten deep shadowed areas, especially on gray days or extremely sunny sessions. As the term suggests, fill flash adds light to deep shadows cast harsh lighting. You can use fill light whenever the background is brighter than the main subject of the photo. When the subject is underexposed due to the deficit of sunlight and other lights or sometimes due to the backlight, fill flash is supplemented to correctly expose the subject. If you are shooting outdoor, don’t rival the sun rather try to complement the sunlight by adjusting the intensity of the fill flash. In order to adjust the intensity, dial down the flash power. You can also contemplate using a diffuser to achieve a natural image.
