This is a 5 in 1 multi photo reflector disc 43 inches / 110 cm. It comes with silver, gold, black, white and translucent surfaces, as those are the most popular reflectors in photography. It also folds into a easy to carry pouch for added convenience.
The silver side is very reflective and brightens both shadows and highlights, but does not change the color of the available light. The gold side side works basically the same way, while adding a warmer color to the image.
The white side brightens 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. The black side just the opposite, and is used to subtract light and create shadows in certain areas.
In the middle of the frame is a translucent material which is used as a diffuser. This side is usually held directly above the subject to soften the sun’s natural light. It will always go between the light source and the subject.
