Lighting design  is the deliberate use of light to achieve a practical or aesthetic effect.

Cue is generally the trigger for an action to be carried out at a specific time or a recorded lighting state in a narrower sense. Cue is one sequence of a performance.

Crossfade is a blending of the current and next cue. One set of lights is being dimmed and the other are coming on.

Hardpatch is the physically interconnected circuits on stage with the respective “dimmers”.

Softpatch is the assignment of interconnected numbers in graphical interface of a lighting console.

Wait (follow) is the time, for which the actual cue is running a after its expiry, it starts blending automatically into another cue.

Delay (Time to go) is the delay of the start of a change from its launching by a button – useful in situations where the operator has to execute another action.

DMX512 (Digital Multiplex) is a standard for digital communication networks that are commonly used to control stage lighting and effects.

Key light is visually dominant lighting of a section of a scene, which is essential.

Fill light – the additional light completes the context of the scene.

Contrast is a difference or an interval between  two chromatic effects directly confronted.

Media servers are machines working comprehensively with visual information and it is common that optional masks and features are implemented in them for easier videomapping.

McCandless Method is a particular approach to providing stage lighting.

Composition is the placement or arrangement of visual elements or ingredients in a work of art, as distinct from the subject of a work.

Rule of thirds is a “rule of thumb” or guideline which applies to the process of composing visual images.

Golden ratio – two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities.

Framing is the presentation of visual elements in an image, especially the placement of the subject in relation to other objects.

Process

Technical rehearsal is a rehearsal that focuses on the technological aspects of the performance.

Dress rehearsal  is a full-scale rehearsal where performers work out every detail of the performance.

Previews are a set of public performances of a theatrical presentation that precede its official opening.

A lighting control console (also called a lightboard, lighting board, or lighting desk) is an electronic device used in theatrical lighting design to control multiple lights at once.

Luminous intensity is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye.
