Filters for black and white photography perform a variety of filtration effects including contrast control, enhanced skin tones, tonal corrections and more dramatic landscapes. Although originally intended for use with black and white film, this filter can also be used as a creative tool in color imaging. Create dramatic sky effects, emphasizing cloud contrast for landscapes. Simulate a moonlit scene at midday with slight underexposure. Use with infrared film to yield extreme contrast with skies, turn foliage white and cut through fog and haze.
