Why spend more money than this flash diffuser will cost? Connoisseurs know that such a diffuser of course, only in relatively small spaces or at a short shooting distance provides really soft light, and that he swallows around two stops of light. So Lift ASA setting or open aperture accordingly, or observe a shorter range at lightning calculation by the automatic camera. It is just a little help to spread a more or less point light source of a compact flash attachment and does not replace the light well of a studio flash with significantly larger luminous area. Nevertheless, the effect of the diffuser is considerable.
