Formatt Hitech 6 x 6" #25 Red Filter

The Hitech 6 x 6" #25 Red Filter is a basic contrast filter, primarily for use with black and white film. This red filter dramatically darkens skies, cuts through haze, and increases overall contrast. When compared to the orange #21 filter, the #25 produces very dark, almost black skies and a surreal contrast between foliage, clouds, and sky.
