The Westcott 40.5" 5-in-1 Collapsible Reflector is versatile in the field and in the studio, providing shadow-lightening detail in your subject, using available, or studio lighting. It starts out as a translucent white disc -- perfect for softening direct sun, or lights without diffusion. Use the removable, reversible zippered slipcover to reflect light into shadow areas of your subject. Your choice of color -- silver, gold, white, black mix -- will be determined by the lighting conditions, and your personal preference.
