Orange Filter. This orange filter noticeably darkens skies, helps to cut through haze, and improves overall contrast. When compared to a yellow filter, an orange filter creates a greater separation between clouds and sky and further lightens yellows and reds within the scene.

Green Filter. This green filter lightens the appearance of green elements within a scene. Dark green foliage, clothing, or backgrounds that may appear overly dark when reproduced in black and white are instead brightened or are more balanced to tones rendered from yellows and reds.
