Made exclusively for the Studio Essentials standard 7" reflector, the Barndoors with Color Gel Set combines control with the means for creative expression. The bundle's four-leaf barndoors clip onto the front of the reflector. Swinging one or more leaves in the path of the light allows you to light areas of the subject that you want while keeping light from areas where you don't want it. The included honeycomb grid narrows the beam spread, adding yet another means of control. The bundle also includes red, yellow, green, and blue filters for creative effects.
