Opteka BC-10 Universal Double-Sided 7.5 X 4-Inch Bounce Card for External Camera Flashes
The Opteka BC-10 Bounce card is a 4 x 7.5" two-sided bounce card, made of a tough black ballistic nylon on one side and a while polymer on the other. The white side can be used as a standard bounce card, to bounce and scatter the light output of the flash. The black side can be used to keep light from flaring into your lens when using a flash as a background or hair light.
