Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world cameras. The effect produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of ...
A typical studio lighting configuration will consist of a fill source to control shadow tone, a single frontal key light to create the highlight modeling clues on the front of objects facing the camera over the shadows the fill illuminates, one or more rim/accent lights to create separation between foreground and background, and one or more ...
A common artificial lighting strategy that creates an overall appearance similar to natural fill places the fill light on the lens axis so that it will appear to cast few if any shadows from the point of view of the camera, which allows the key light that overlaps it to create the illusion of 3D in a 2D photo with the same single-source ...
Without lighting models, replicating lighting effects as they occur in the natural world would require more processing power than is practical for computer graphics. [14] This lighting, or illumination model's purpose is to compute the color of every pixel or the amount of light reflected for different surfaces in the scene. [ 15 ]
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.

In this case, adjusting the camera's exposure settings (which only applies changes to the whole image, not selectively to parts of the image) only allows the photographer to choose between underexposed shadows or overexposed highlights; it cannot bring both into the useful exposure range at the same time.
The addition of a fourth light, the background light, makes for a four-point lighting setup. The background light is placed behind the subject(s), on a high grid, or low to the ground. Unlike the other three lights, which illuminate foreground elements like actors and props, it illuminates background elements, such as walls or outdoor scenery.
