The Tiffen 4 x 5.65" Yellow #6 Filter is a basic contrast filter, primarily used with black and white film. This yellow filter slightly darkens skies, helps reduce haze and enhances overall contrast. It is a common contrast filter for black and white photography, producing an accurate tonal range and partially compensating for the blue sensitivity of panchromatic films.

This filter has a filter factor of 1.2x, requiring an increase of approximately 0.3 f-stop for normal exposure. Tiffen filters are manufactured using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding it flat to a tolerance of one ten-thousandth of an inch. It measures 4 x 5.65" / 101.6 x 143.5 mm.
