Tungsten (also called wolfram) [14] [15] is a chemical element; it has symbol W and atomic number 74. It is a rare metal found naturally on Earth almost exclusively ...
Tungsten slide films are designed to provide accurate exposure as well as color rendition even when exposed according to exposure meter readings indicating a long exposure; tungsten film can be used to avoid reciprocity failure which often occurs when using long exposures. Common film speeds for tungsten-balanced slide film are ISO 64, 160, and ...
Professional-quality, medium-speed, tungsten-type color reversal film with natural color reproduction for product photography, interiors and for reproducing illustrations and paintings (RTP). Emulsion changed in 1983 and name changed to FujiChrome Professional T. Emulsion changed again in 1987

Color conversion, the opposite of the 80A; this is a warming filter that takes an outdoor scene lit by sunlight (which has a color temperature around 5500 K) and makes it appear to be lit by tungsten incandescent bulbs around 3400 K. This allows an indoor balanced film to be used to photograph outdoors.
Matching the sensitivity of the film to the color temperature of the light source is one way to balance color. If tungsten film is used indoors with incandescent lamps, the yellowish-orange light of the tungsten incandescent lamps will appear as white (3200 K) in the photograph. Color negative film is almost always daylight-balanced, since it ...
The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. The study of chemical structure by means of energy absorption and release is generally referred to as spectroscopy .
CIE standard illuminant A is intended to represent typical, domestic, tungsten-filament lighting. Its relative spectral power distribution is that of a Planckian radiator at a temperature of approximately 2856 K. CIE standard illuminant A should be used in all applications of colorimetry involving the use of incandescent lighting, unless there ...
