5. Fill-in flash
A burst of flash, ideally from an off-camera unit, will flood shadows with light and reduce the contrast of a harshly-lit scene dramatically. It also puts you in control of light-levels and exposure.
For the best results the flash should be softened with some form of diffuser or soft box and positioned towards the opposite side of the subject to the ambient light source so that the shadows receive light.
Modern TTL (Through The Lens) flash metering systems do all the hard work for you, but you can adjust the brightness of the flash output using the flash exposure compensation controls on the gun or camera.
