Tiffen 72mm 21 Orange Optical Glass Camera Lens Filter

The Tiffen #21 Orange Filter is designed to enhance contrast in black and white photography. It absorbs blue and blue-green colors, making blues appear darker, which is ideal for dramatic skies in landscape or aerial photos, and enhancing water in marine shots. Tiffen filters use ColorCore technology, where filter material is laminated between two pieces of optical glass, then ground and polished, and finally mounted to a metal ring. Features: * Deeper contrast than Orange 16 filters * Absorbs blue and blue-green colors * 72mm diameter * Primarily for black-and-white imaging * Optical glass construction
