John the Baptist (John in the Wilderness), by Caravaggio, 1604, in the Nelson-Atkins Museum of Art, Kansas City. Tenebrism, from Italian tenebroso ('dark, gloomy, mysterious'), also occasionally called dramatic illumination, is a style of painting using especially pronounced chiaroscuro, where there are violent contrasts of light and dark, and where darkness becomes a dominating feature of the ...
From left to right: an original photo with no bokeh or blur; the same photo with synthetic bokeh effect applied to its background; the same photo with Gaussian blur applied to its background. Bokeh can be simulated by convolving the image with a kernel that corresponds to the image of an out-of-focus point source taken with a real camera.
In lighting design, backlighting is the process of illuminating the subject from the back. In other words, the lighting instrument and the viewer face each other, with the subject in between. This creates a glowing effect on the edges of the subject, [1] while other areas are darker. The backlight can be a natural or artificial source of light.
Ambient light sources illuminate objects even when no other light source is present. [6] The intensity of ambient light is independent of direction, distance, and other objects, meaning the effect is completely uniform throughout the scene. [6] This source ensures that objects are visible even in complete darkness. [5]
The effect produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of an extremely bright light overwhelming the camera or eye capturing the scene. It became widely used in video games after an article on the technique was published by the authors of Tron 2.0 in 2004. [1]

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 ...
