At times, a burst of flash can enhance an outdoor scene. I'm not talking about the harsh, overpowering "deer in the headlights" type of flash power. Definitely not! I'm talking about fill flash, in which the light from the flash mixes with the existing light (also called ambient, or available, light) to illuminate a subject in a natural and unobtrusive way.

Supplemental light can be accomplished with either built-in flash (which usually offers a fill flash mode) or external flash unit (a separate flash unit designed to work with a specific camera model and its exposure system). Consider these scenarios:
Unflattering facial shadows, for example, can mar a portrait captured under a bright overhead sun. Or a portrait subject under a shade tree often appears dark (from the shadows) in contrast to a bright-sunlight background. In each case, fill flash could save the shot by brightening the subject.
In addition, under a white or gray sky, you can add a touch of fill light to create little sparkles or twinkles - also called catchlights - in a portrait subjectís eyes. Also, while overcast or shade delivers pleasingly soft and even light, sometimes the colors appear muted - thatís where a shot of extra light (via fill flash or a reflector to bounce light) can help make the colors pop. See accompanying Overcast Portrait photo.

In mixed lighting, an awesome foreground can be lost in shadow while the bright sunlit background grabs the attention. But with everything properly exposed - both the background and the flash-illuminated foreground - the whole photo is balanced, with nothing in the picture looking too dark or too light. Thatís the point of fill flash - to make things appear natural-looking, so it isnít obvious you have blasted your close subject with artificial light. See accompanying Sunset Seascape photo by BetterPhoto pro instructor and book contributor Doug Steakley.
- Accessory flash units and most built-in flashes offer ways to control the desired amount of flash. These are especially important when you are trying to balance the light in a pleasing way. You might want enough light to fill in a deep shadow, or you might want only a dash of illumination, or something in between.
- The flash exposure compensation feature allows you to adjust the flash output in one-third or half-stop increments usually up to plus/minus two or three stops. Whatís best? It depends on the circumstances, but with digital, itís easy to figure out! Just take the picture and then study it in playback. Adjust the flash compensation if necessary, then take another photo. Repeat the process until everything looks great.
- Your flash only affects subjects within its reach, not the sceneís ambient or existing light. For instance, if the background looks too dark or light, you can adjust it via your cameraís exposure compensation (the same feature you use to adjust the exposure for non-flash images). Thatís different than flash exposure compensation, which only affects the flash output.
Have fun adding fill light - when necessary - to your outdoor images!
