The Cavision 4 x 5.65" Day for Night Filter is a great way to create images simulating dusk or night-time while filming during the day. This filter is valuable since is enables you to shoot during the day instead of paying overtime to a film crew for night work. This is a huge benefit when working a strict budget or when production time is of critical importance. This unique filter is tinted lavender blue which is, normally, associated with the color of moonlight photography.
