Everyone has taken a photo that didn't turn out quite right because of bad lighting or a flash that produced too much or too little light. A flash can make your subject look washed out, or even downright creepy with bright white skin and red eyes. But with a bounce wall, you can redirect the light to make it less harsh and reduce the shadows. It also means less demonic-looking cats.
Bounce walls can be expensive, but David Hobby of Strobist made this DIY version that uses a wire hanger, some cardboard, a piece of foil, and a few clothespins for a bounce wall that's just as easy on your wallet as it is to build.
