The Rosco Blackwrap®/ Cinefoil, and also Rosco Photofoil™ is made using a flexible .002-inch thick aluminum substrate that is form-holding and both heat and weather resistant. Featuring a matte black coating on both sides, these materials are ideal for masking light leaks and eliminating unwanted reflections. It can quickly be molded to form barndoors, snoots, flags and other light controlling configurations. Lightweight, yet durable, this material can easily be positioned in place with tape, staples or adhesives.
