Arc-light: - a high intensity source in which light is produced by discharge of electricity between two electrodes.

Available light:  a term used for shooting without film lighting, using only the light available in the natural surroundings.

Back-light: lighting an object from behind.

Barn-door: the metal shields hinged in front of a lamp to limit /shape the light it produces.

Bounce lighting: a technique in which light is directed on to a reflective surface, producing a softer, more shadow less effect.

Brutes: a type of arc light producing a high intensity spot.

Color temperature: the measurements of light’s color quality on the Kelvin scale.

Contrast: the difference in intensity between the darkest and brightest parts of the scene to be photographed.

Cross-lighting: lighting which comes from the side of the scene.

Eye-light:  a small, hard light source placed close to the camera, used to pick out an actor’s eyes.

Fill light: secondary lighting used to reveal more detail in shadow areas of the image; also reduces overall contrast.

Flag:  used to shield unwanted light from the lens, or to create shadows. When perforated, it creates shadow patterns and dappled light effects.

Gel: a transparent filter placed in front of a light; different coloured gels can act as colour correction for daylight or tungsten; gels can also be used to colour the light for aesthetics effects.

High-key lighting: lighting which gives an overall brightness to the image, obtained, for example by a soft, diffused light source.

HMI: daylight coloured lights.

Inky-dink: a small incandescent light source.

Key light: the principal light source used to illuminate a scene.

Kicker: this serves a similar function to backlight, placed in a three-quarter-back position at a low angle behind the subject.

Low key lighting: describes a scene usually lit by one principal light source which casts shadows and only partially illuminates the whole image.

Reflectors: a light reflective surface, used chiefly for redirecting sunlight on to the scene in order to fill in shadows.

Rim-light: a form of back light placed so that the edges of a subject are framed by light.  Used to separate the subject from the background.

Scrim: fabric placed on a light to diffuse its intensity.

Soft light: open reflector lights that produce soft and shadow less light.

Source light: refers to light which is intended to came from a source in the image , a window, or a practical light source in the interior such as a table lamp.

Space light: used to provide a very big source of light. A number of space lights are often rigged at ten feet intervals to provide fill lighting over very large interior sets.
