The LEE Filters 100 x 100mm #23A Light Red Filter is a basic contrast filter, primarily for use with black and white film, that strongly darkens blue tones, increases overall contrast, and is often used to emphasize shadows and clouds. Offering greater contrast than the #21 orange filter, this light red filter is especially well suited to photographing skies and producing dramatic effects when shooting outdoors. There is an approximate 4x filter factor with this filter, requiring an increase of 2 stops for normal exposure.
