LEE Filters 4 x 4" #16 Yellow Orange Polyester Filter

The LEE Filters 4 x 4" #16 Yellow Orange Polyester Filter is a basic contrast filter, primarily for use with black and white film, that strongly darkens skies, reduces blues, and increases overall contrast. It provides a more noticeable increase in contrast compared to the #15 deep yellow filter, and also absorbs a small amount of green for darkening foliage. There is an approximate 1.5x filter factor with this filter, requiring an increase of 0.6 stop for normal exposure.
