Q: 8. I'm trying to reduce or eliminate the shadow caused by those wearing baseball-type hats outdoors. Can this be used as a fill-flash at 15 feet?

A: This would depend on the angle of the shot. You can eliminate that shadow with any flash as long as you use a low angle. Keep in mind this flash is aimed toward macro photography. It is not very powerful for long distance. I have not tried its threshold, but I would not use it more than 6 feet. To eliminate the hat shadow you can also use a white reflector from a low angle with any flash if there is some environmental light. Try that before purchasing anything you might regret.
