Bounce Flash
Aiming a flash at a ceiling or wall so the reflected light, not the direct beam, illuminates the subject.
Measured in

In depth
Bouncing converts a tiny hard source into a surface several square metres across, which is why it transforms on-camera flash from harsh to acceptable. It costs two to three stops of power, requires a reasonably close and neutral-coloured surface, and puts the light overhead — so bouncing off a wall to the side often flatters more than a ceiling bounce.
Examples in practice
Bouncing off a white ceiling at a reception replaces the flat direct-flash look with soft overhead light and natural shadows.
