The 1mm Schneider 4 x 4″ Indigo True-Streak Filter is designed to simulate an anamorphic streak effect regardless of the lens, anamorphic or not. Upon light sources, such as the sun, a light bulb, or a candle, long colored streaks emanate to draw attention to a specific part of the frame or create a visually dramatic effect. Depending on the strength and lighting selected, you can easily achieve in camera a variety of results, from subtle to dramatic streak effects.
