The Cokin Filter Z046 FLD is used to correct the greenish hue that occurs when shooting with daylight film under fluorescent lights.
Note
A FL filter does not guarantee 100% correct colour balance when shooting under fluorescent light. The filter is intended for moderate correction and will not necessarily ensure perfect colour reproduction. Fluorescent lamps operate at many different colour temperatures and often require more filtering for precise results. For specific filtering and professional use, it is best to use a spectrometer in combination with colour correction filters such as a CC30M filter when shooting under fluorescent lights. This is the only correct way to obtain an exact colour correction.
