Doca - Correct you are. You would use the flash for fill. It's the type of thing you use when shooting portraits outdoors. Would be nice if you could put the sun to your back and get all that wonderful light on the subjects face, but then they end up squinting and looking mad, so you turn them so the sun isn't in their eyes and add fill flash to bring light to the shadows, evening it all out and making it look more natural. You can also do this when someone is wearing hat and you want to get good, even exposure on their face. Another option is a reflector. -=>Donald
