Create a cleaner image with Dinkum Systems products from BarnDoor Lighting. Dinkum Systems lens shades allow you to build convenient and flexible mounts for cameras and lens shades, AKA French flags. These handy add-ons are used to prevent camera lens flare, which is produced by a light source that shines directly into the lens and creates an overall haze to the image or adds a small line of blue dots in the image. Sometimes, lens flares are used to add a creative element, but most often they are undesirable and cinematographers prefer if they are eliminated.
