Using an external flash on top of my camera instead of the pop-up one built into my camera gives me much more natural-looking photos. So I use it a lot; but because I feel I have not really mastered flash lighting, I keep everything in a program mode. My camera is set to “P” and my flash is in its program mode. The real trick, however, is the bouncing of the light off of the ceiling. With many external flashes, the head of the flash swivels so that you can make the light from the flash bounce off of a wall or ceiling. Below are two examples of direct flash, like your built-in pop-up flash, versus bounce flash. The images with bounce flash feel more natural – the shadow in the background disappears and the overall result is not harsh. An external flash does make your camera heavier, but the results are so flattering that to me it is worth the extra weight. Be sure when you bounce a flash, the wall of ceiling is white or very light. If you bounce off of a green wall, for example, the photo will have a green cast.
