The Top 10 Photography Lighting Facts You Should Know
Bouncing light acts as diffusion
4. Bouncing light acts as diffusion. Aim a narrow light source at a broad, matte surface—such as a wall, ceiling, or matte refiector—and it not only refiects the light but also diffuses it by scattering it over a wider area.
Use a shiny refiector, though, and the light will stay fairly narrow on the bounce. The most extreme type of shiny refiector—a mirror—will keep the light focused pretty much as narrowly in the refiection.
Tip: Crumple a big piece of aluminum foil, spread in out again, and wrap it around a piece of cardboard, shiny side out. It makes a good reflector that’s not quite as soft in effect as a matte white surface—great for adding sparkly highlights.
