Prior to 1935 and the introduction of Kodachrome color slide film, the average photographer had no choice---black and white photography was the only option. As with any art form, people looked for disinctive ways to stretch the limits and produce original work. One way photographers approached control over their vision was through the use of filters.
Color Filters
Panchromatic black and white films are sensitive to all colors of light, even though they result in a monochrome image. The principle of like and complementary colors can be used to alter tone relationships in a black and white photo. Most dramatically, a 25A red filter can block the light of a blue sky while allowing white clouds to pass, creating vivid contrast between the two. Black and white film is more sensitive to blue light in general, so a yellow filter often is used to give an effect similar to the human eye.
Polarizing Filters
The effects of polarized light affect black and white film in a similar way as color film. Reflections in windows and glare on many surfaces may be reduced. Increased contrast in blue skies can also be achieved with polarizing filters, depending on the location of the sun and the direction of the camera. Older, manual cameras can use linear or circular polarizing filters, while newer auto-focus cameras require circular polarizers to avoid interference with focus and metering systems.
Ultraviolet Filters
Ultraviolet (UV) filters are commonly placed on cameras to both reduce the effects of ultraviolet light and serve as a functioning protective layer for the lens. UV light scatters easily and reduces contrast overall. While it isn't an immediately obvious quality issue in most cases, overall sharpness and clarity are improved when the effects of UV are removed.
Darkroom Use
Filters are important for home darkroom enthusiasts working with black and white film. Variable contrast photographic printing papers incorporate two layers of emulsion, each with different color sensitivities. By using different filters between the enlarger lens and the print, the effective grade of contrast of the paper is changed, allowing for a wider range of negatives to be printed effectively.
