The Lee Tungsten Fluorescent (TFL) Polyester Filter Set is a great choice for the architectural photographer or anyone shooting with mixed lighting and tungsten film. Lee makes kits specifically for shooting under fluorescent lighting: One for daylight film and one for tungsten film. This kit is for use for tungsten film and includes an FL3600-B, FL4300-B and FL5700-B.

An FL-D filter is used when you wish to correct for the greenish tone that appears when shooting daylight film under general purpose fluorescent lighting. An FL-W filter is used to balance daylight film under warm white or white type fluorescent lamps. An FL-B filter is used to correct the color balance when shooting tungsten film under fluorescent lighting.

NOTE: The FL series of filters alone does not always guarantee 100% correct color balance when shooting under fluorescent lighting. They are general purpose filters intended for moderate correction and will not, by themselves, necessarily provide perfect color rendition.

Fluorescent lamps burn at many different temperatures and often require more demanding filtration for exact results. For specific filtration and professional use, it is strongly recommended that a color temperature meter be employed along with Color Correction filters (i.e.CC30M) when shooting under fluorescent lighting. This is the only proven way to achieve exact color correction.
