The spotlight effect is an extension of several psychological phenomena. Among these is the phenomenon known as anchoring and adjustment, which suggests that individuals will use their own internal feelings of anxiety and the accompanying self-representation as an anchor, then insufficiently correct for the fact that others are less privy to those feelings than they are themselves.
In computer graphics, the overall effect of a light source on an object is determined by the combination of the object's interactions with it usually described by at least three main components. [11] The three primary lighting components (and subsequent interaction types) are diffuse, ambient, and specular.
The spotlight effect, the phenomenon where people tend to believe that they're noticed more than they really are, is a term Gilovich coined. In a paper he wrote with two graduate students in 1999, he explained that "because we are so focused on our own behavior, it can be difficult to arrive at an accurate assessment of how much–or how little ...
Pearlescence is an effect related to iridescence and has a similar cause. Structures within a surface cause light to be reflected back, but in the case of pearlescence some or most of the light is white, giving the object a pearl -like luster. [ 16 ]

In the photographic industry, a "gobo" describes any opaque, usually black, panel, or "flat", [13] of any dimension, that goes between a light source and photographic subject (such as between sun light and a portrait model) to control the modelling effect of the existing light or, used as a "cutter", to create shadows; [14] or even to control ...
In volumetric lighting, the light cone emitted by a light source is modeled as a transparent object and considered as a container of a "volume". As a result, light has the capability to give the effect of passing through an actual three-dimensional aerosol (e.g. fog, dust, smoke, or steam) that is inside its volume, just like in the real world.
The effect is named after the infrared photography pioneer Robert W. Wood, and not after the material wood, which does not strongly reflect infrared. The other attributes of infrared photographs include very dark skies and penetration of atmospheric haze, caused by reduced Rayleigh scattering and Mie scattering , respectively, compared to ...
