I've noticed that on cans of tungsten balanced film, Kodak specifies the use of an 85 filter for daylight color conversion, while Tiffen's website specifies an 85B as the proper filter for balancing tungsten film to daylight. Specifically, Tiffen lists the 85 as converting daylight to 3400K, while the 85B converts daylight to 3200K.

Tungsten light, when combined with natural daylight, makes for a beautifully soft, organic effect. Conversely, combining tungsten with a cool, blue evening light casts incredible drama on the subject. This is especially impactful in portraiture but is 100 percent useful for still lifes and art photography.

The 80-series of filters are meant for correcting colour when using daylight-balanced film under tungsten lighting. If you are shooting under fluorescent light, you might actually need a FL-D filter (a purple filter, to counteract the green hue of fluorescent tubes). The filter you need depends on the exact colour/temperature of the lighting.

The Tiffen 52mm 85C Color Conversion Filter helps to decrease the color temperature from 5500 to 3800K, allowing the use of tungsten-balanced film in daylight conditions.
