Tiffen 49mm 85B Filter

Sunlight, daylight, incandescent, fluorescent, and other artificial light sources all have color characteristics that vary significantly. 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.

Using tungsten film in daylight will produce a bluish cast. Use this filter to convert tungsten film to daylight.
