Translucent Panel: Used as a diffuser. It is usually held directly above the subject to soften the sun's natural light. Silver Cover: Very reflective and brighten both shadows and highlights but does not change the color of the available light. Gold Cover: Work basically the same way while adding a warmer color to the image. White Cover: Brighten up the shadows to produce a softer light. It is not as bright as the silver side so you can get closer to your subject. Black Cover: Subtract light and create shadows in certain areas.
