Sunlight, daylight, incandescent, fluorescent, and
other artificial light sources all have color charac-
teristics that vary significantly. Filters give you better
images by adjusting for these light variations.
Film and video are rated for a particular color
temperature such as that of daylight or tungsten
light. Filters are used to correct differences in color
temperature between the recording medium and
the light source.
