In the evening, you can choose atmospheric lighting without having to worry about overpowering orange tones. Create night in broad daylight. The COKIN conversion blue filters eliminate or reduce the strong orange tones produced by tungsten or halogen lamps. The COKIN conversion blue filters replace the flat, uniform lighting of a flash with a moody, intimate illumination featuring shaped shadows, without compromising the underlying color tones. The COKIN conversion blue filters are also suitable for lanterns at parties, shop windows, and monuments at night. During the day, when you underexpose with one or two stops, the COKIN conversion blue filters create a moonlit landscape. Television and film use the same technique, known as American night. Depending on the subject being photographed, you can achieve a romantic atmosphere.
