Donkeys, also called burros and asses, are found throughout the world. They look a lot like their cousins, but have long, floppy ears and tend to be stockier than horses or zebras. News
The above is not a true Color Temperature chart. Instead it is a hybrid, showing the color temperatures of light sources most commonly encountered in professional imaging. In our scale, tungsten-halogen has a color temperature of 3200Â°K. Household fluorescents are accepted to be around 4500Â°K, depending on the lamp. (They are shown for reference, but would not be part of a true Color Temperature chart, for reasons described below).
For example, if a light source has a color temperature of 3000 K (often found in older microscopes with a tungsten lamp), the microscopist could adjust the apparent color temperature to 3200 K with an 82A filter for use with type B tungsten-balanced film, or to 3400 K with an 82C filter for use with type A film.
