Examples are interior photographs made in offices, reception areas, factory halls, and subway stations, as well as night-time photographs of office buildings whose windows would appear green because their interiors are usually illuminated with fluorescent tubes. The abbreviation F-Day stands for "Fluorescent Light - Daylight", which reflects the fact that these filters are designed for the most commonly used type of fluorescent tube, which emit light of a color that resembles daylight. Because fluorescent tubes are not "thermal radiators", they do not produce a continuous spectrum like those of the sun and incandescent bulbs. Instead, they emit a sharply defined line spectrum that has high intensity spikes in the green region. Our eyes barely perceive this special green, but most color films are especially sensitive to those wavelengths and they react wi ProductSiteLaunchDate : 2003-06-17T00:00:00-00:00 Size : 30x21x0.1cm SupplierDeclaredDgHzRegulation : not_applicable UnspscCode : 45121600 WarrantyDescription : Limited Warranty WaterResistanceLevel : not_water_resistant ZoomType : Optical Zoom
