Tiffen Series 9 #9 (3) Yellow Filter

The Tiffen Series 9 #9 (3) Yellow Filter is a basic contrast filter, primarily for use with black and white film. This medium yellow filter slightly darkens skies, helps to cut through haze, and improves overall contrast. It is a common contrast filter for black and white photography, producing an accurate tonal range and compensating for the blue sensitivity of panchromatic film.
