A Behind The Scenes Look at The Making of a Lee Filter

Lee Filters is a world-class producer of high-quality filters for both photography and cinematography, and now we have a chance to see what goes into making these high-end accessories. Keep in mind that these filters aren’t made by some machine on an assembly line; each Lee Filter is made by hand, and in this video Mike Browne shows you what that process entails from liquid start to solid finish.
