In blackk and White, this Red 25 filter can 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. Filters for blackk 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 blackk and white film, these filters can also be used as a creative tool in color imaging.
