The LEE Filters 6 x 6" #8 Yellow Polyester Filter is a basic contrast filter, primarily for use with black and white film, that slightly darkens skies, helps to cut through haze, and improves overall contrast. It is the most common contrast filter for black and white photography, producing an accurate tonal range and compensating for the blue sensitivity of panchromatic film. There is an approximate 1.3x filter factor with this filter, requiring an increase of 0.3 stop for normal exposure.
This 6 x 6" / 152.4 x 152.4mm filter is manufactured from high-quality polyester materials, is durable and easy to clean, and can be cut-to-size or mounted within filter frames for use.
