To use the diffuser:

1. Pull the diffuser and reflector

panels out of their slot in the
flash head.

2. Push the reflector back in, and

let the diffuser lay flat against
the flash lens.The diffuser also
softens the light, providing an
alternative when no surface is
available for bouncing the flash
(see Bouncing Your Flash on page 24).
