Tiffen 77mm 21 Orange Optical Glass Filter for Black and White Photography

The Tiffen #21 Orange Filter is designed to enhance contrast in black and white photography by creating separation between tones. It effectively absorbs blue and blue-green colors, rendering blues darker for dramatic effects in landscapes, aerial photos, and marine scenes. Tiffen filters are manufactured using ColorCore technology, laminating the filter material between two pieces of optical glass, which is then ground and polished.
