Tiffen Viewing Filters Type:#1 Black and White By using this IR correctionContrast Viewing Filters Balancing lighting by eye is a matter of experience. Decisions can be aided through the use of contrast viewing filters. These are designed to handicap the eye, with its much greater range of apparent densities, to resemble the range of the various types of film. Use contrast viewers to judge relative highlight and shadow densities. There are viewers for black and white film, as well as various viewer densities for color film.
