Unreferenced date December 2009 In stage lighting , a fade is a gradual increase or decrease of the illuminance intensity of light projected onto the stage. The term fade in refers to gradually changing the lighting level from complete darkness to a predetermined lighting level. A fade out also known as fade to black refers to gradually decreasing the intensity of light until none is shining on the stage. A crossfade is when lighting levels are gradually altered from one setting to another. A fade in is sometimes called a build , and where this terminology is used, a fade is understood to be a fade out. In nearly all theatrical lighting designs, multiple lighting instruments are used to illuminate the stage at any one time. The instruments are controlled by a lighting technician from a dimmer board or lighting control panel engineering control panel . A fade refers to a change in lighting illumination for the entire stage. Thus, the intensity of many lighting instruments are often altered with a single fade, especially with newer digital control systems like DMX lighting DMX , which uses a serial data stream to control up to 512 dimmers or other compatible fixtures, via a single twisted pair of wires. DMX consoles are largely computerised, thus allowing digital process control from multiple input devices, and synchronisation via MIDI , SMPTE etc. The terms fade in , fade out , and fade to black were borrowed by Hollywood, and are used in the formal structure of screenplay s.

The higher the lighting ratio, the higher the contrast of the image the lower the ratio, the lower the contrast. Light can be measured in footcandles . A key light of 100 footcandles and a fill light of 100 footcandles have a 1 1 ratio a ratio of one to one . A keylight of 800 footcandles and a fill light of 200 footcandles has a ratio of 4 1. The ratio can be determined in relation to F stop s since each increase in f stop is equal double the amount of light 2 to the power of the difference in f stops is equal to the first factor in the ratio. For example, a difference in two f stops between key and fill is 2 squared, or 4 1 ratio. A difference in 3 stops is 2 cubed, or an 8 1 ratio. No difference is equal to 2 to the power of 0, for a 1 1 ratio. In situations such as motion picture lighting sometimes the lighting ratio is described as key plus fill to fill alone.

Often task lighting refers to office lighting, where the task light is used to increase illuminance on the reading area. However, the illuminance level is not the only factor governing visibility. Contrast vision Contrast is also important, and a poorly positioned light source may cause contrast reduction, resulting in loss of visibility. Therefore, it can be argued that the most important purpose of task lighting in the office is not increasing illuminance, but improving contrast. Different strategies for office task lighting exist. The three main approaches are Localised average lighting, where a lamp supplies both ambient light and task light Freely adjustable task light Asymmetric task light, where the lamp is placed at the side of the work area There are also other approaches to office task lighting, for example under shelf luminaire s. Other instances of task lighting are in machinery, where a specific work area needs illumination, and in workshops, where a task light may illuminate the actual working area. Special instances of task lighting are examination and operation lights for medicine and surgery , as well as the dentist s lamp.

Image Rembrandt lighting.png thumb The typical Rembrandt lighting setup Rembrandt lighting is a lighting technique that is sometimes used in studio portrait photography . It can be achieved using one light and a reflector, or two lights, and is popular because it is capable of producing images which appear both natural and compelling with a minimum of equipment. Rembrandt lighting is characterized by an illuminated triangle under the eye of the subject, on the less illuminated side of the face. It is named for the Dutch painter Rembrandt , who often used this type of lighting. Description Normally, the key light is placed high and to one side at the front, and the fill light or a reflector is placed half height and on the other side at the front, set to about half the power of the key light, with the subject, if facing at an angle to the camera, with the key light illuminating the far side of the face. The key in Rembrandt lighting is creating the triangle or diamond shape of light underneath the eye. One side of the face is lit well from the main light source while the other side of the face uses the interaction of shadows and light, also known as chiaroscuro , to create this geometric form on the face. The triangle should be no longer than the nose and no wider than the eye. This technique may be achieved subtly or very dramatically by altering the distance between subject and lights and relative strengths of main and fill lights. It is a common photography technique.
