The 5.65 x 5.65” Dark Red #29 Glass Filter from Tiffen is used for black and white photography. It performs a variety of filtration effects including contrast control, enhanced skin tones, tonal corrections, and more dramatic landscapes. Although originally intended for use with black and white film, this filter can also be used as a creative tool in color imaging.
The filter is manufactured using Tiffen’s ColorCore technology, a process that entails permanently laminating the filter material in between 2 pieces of optical glass that are ground flat to tolerances of a ten-thousandth of an inch, then mounting them in precision metal rings.
