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. For convenience, Lee offers some very specific filters for these situations.
This filter is appropriate for achieving a natural color balance when using tungsten film under Warm White 3600K bulbs.
Lee polyester filters are made from lightweight, optical polymeric materials and are available in 3 x 3" (75 x 75mm) and 4 x 4" (100 x 100mm).
