In the US lighting industry, foot-candles are a common unit of measurement used by architects to calculate adequate lighting levels. Foot-candles are also commonly used in the museum and gallery fields in the US, where lighting levels must be carefully controlled to conserve light-sensitive objects such as prints, photographs, and paintings, the colors of which fade when exposed to bright ...

Brightness is an attribute of visual perception in which a source appears to be radiating or reflecting light. [1] In other words, brightness is the perception elicited by the luminance of a visual target. The perception is not linear to luminance, and relies on the context of the viewing environment (for example, see White's illusion).
A foot-lambert or footlambert (fL, sometimes fl or ft-L) is a unit of luminance in United States customary units and some other unit systems. A foot-lambert equals 1/π or 0.3183 candela per square foot, or 3.426 candela per square meter (the corresponding SI unit).
A form of level of detail management has been applied to texture maps for years, under the name of mipmapping, also providing higher rendering quality. It is commonplace to say that "an object has been LOD-ed " when the object is simplified by the underlying LOD-ing algorithm as well as a 3D modeler manually creating LOD models.
It is a junior-level feeder formula that uses the same single seater chassis as the pan-European Euroformula Open Championship. The series will be the first with the new branding as a feeder series for the Super Formula championship. The nomenclature is similar to that of IndyCar, whose support series as formerly used the "Lights" moniker.
When seen from below by a predator, the animal's light helps to match its brightness and colour to the sea surface above. Counter-illumination is a method of active camouflage seen in marine animals such as firefly squid and midshipman fish, and in military prototypes, producing light to match their backgrounds in both brightness and wavelength.
The larger F.3, which was less popular with its crews than the more maneuverable F.2A, served in the Mediterranean as well as the North Sea.. In 1920, the Canadian Air Board sponsored a project to conduct the first-ever Trans-Canada flight to determine the feasibility of such flights for future air mail and passenger service.
