Hoya 52mm Red 25 Multi Coated Filter

The most popular of the contrast filters for black and white photography, Red creates dramatic effects by brightening red and orange while darkening blue and blue-green in sky, water and architectural scenes. With underexposure, the red filter may be used to simulate a moonlit scene at midday. With infrared film, the filter gives extreme contrast to skies, turning foliage white and cutting through fog and haze. Multi coated for maximum flare protection, red filters are available in most popular sizes.
