It has been awhile since I have mentioned one of my favorite subjects, fill flash. I touched on fill flash when I discussed Outdoor Portraiture and shared a photo of Captain Jack Sparrow. Even with the advancements of my Nikon D700 digital SLR camera, I still use a Nikon Speedlight set to balanced fill flash (see your camera and flash manuals for this setting. Point and Shoot camera owners, look for Sun Portrait or similar mode).
This Indian statue on Main Street USA in the Magic Kingdom of Walt Disney World was a willing subject to show you the difference between not using and using flash in bright sunlight. The photo on the left without flash has dark shadows and muted colors. The photo on the right with flash brings up the colors and eliminates the shadows. Especially notice the difference around the eyes.
Before you mention it, I know there is some reflection from the flash on the statue’s face. I do not expect that to happen with real people unless you are photographing Joan Rivers or Wayne Newton. :D To prove my point here are a few more portraits of some of the characters found on Main Street USA.
Notice when I am in close to the people, I set my flash at -1 power. That is a good starting point. I will change the power plus or minus until I get the best exposure possible. The last photo of Princess Ariel, I needed full power because of the distance she was from me.
