In the 1830s, lighting transitions were the most astonishing effects used to manipulate mood or atmosphere by stimulating dynamic lighting of indoor and outdoor sources. The manipulation of light and shadows in real time are done through lighting transitions they were used to decorate scenes, reveal or conceal certain parts, and change focus (de Melo and Ana Pavia, 2007). вЂњThe functions of shadow include deп¬Ѓning spatial relationships modeling contextualizing revealing and concealing parts of the scene aesthetics and, expression of aп¬Ђective statesвЂќ (de Melo and Ana Pavia, 2007). Within the absence of light, shadows are able to occur. Other characteristics can define exposure levels, the levels of hardness or softness, the shape, and the decaying of light within the distance (de Melo and Ana Pavia, 2007). Both can apply to the luminance or illumination, the physical amount of light (Ware, 2008). Lightness is a term used to described surface colors while brightness generally describes emitted light. Specific elements such as the ones listed defines light as a point, direction, or spotlight, the angle of the light, and the definition of the color from hue, saturation, and brightness (de Melo and Ana Pavia, 2007). Lighting can function as an expression of affectionate states through the manipulation of various light elements (de Melo and Ana Pavia, 2007). вЂњA detailed and careful characterization of visual tasks under different lighting conditions вЂ“ the stimulus вЂ“ and a variety of important methods for measuring visual performance as those conditions are varied вЂ“ the responseвЂќ (Davis, 2014). Lighting designers exploit these uses everyday to create an appropriate stimulus that would receive a desired response (Davis, 2014). Persuade feelings towards a certain space.Provoke specific feelings of a specific space.

During any type of theatrical production, the mood and emotion of the audience can change through the intensity, color, angle, and pattern of the lighting (Basa, 2014). Emotional lighting can be described as the potential of lighting being used to induce relaxation, motivation, and intimate atmosphere (вЂњEmotional Lighting,вЂќ Right Light) it is simply lighting used to provoke emotions.
