Three-point lighting is a standard method used in visual media such as theatre, video, film, still photography, computer-generated imagery and 3D computer graphics. [1] By using three separate positions, the photographer can illuminate the shot's subject (such as a person) however desired, while also controlling (or eliminating) the shading and ...
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 ...
I'd suggest that Three-point lighting is a more commonly used term than 4-point lighting setup, and that 4-point lighting is a subset of it. Consequently, I recommend merging 4-point lighting setup into Three-point lighting. --Jeremy Butler 13:39, 17 February 2006 (UTC) I totally agree with Jeremy Butler. Oliver Bronson Done.
This problem was also solved for polygonal rooms by George Tokarsky in 1995 for 2 and 3 dimensions, which showed that there exists an unilluminable polygonal 26-sided room with a "dark spot" which is not illuminated from another point in the room, even allowing for repeated reflections. [1]
Light poverty is the state or condition in which people or communities lack artificial or electric light after sunset. This originates from many social and economic reasons, including inability to afford efficient lighting. [1] Light poverty may also occur when a country's national grid has not electrified rural areas requiring light. [2]
A 3-way lamp, also known as a tri-light, is a lamp that uses a 3-way light bulb to produce three levels of light in a low-medium-high configuration. A 3-way lamp requires a 3-way bulb and socket, and a 3-way switch. In 3-way incandescent light bulbs, each of the filaments operates at full voltage. Lamp bulbs with dual carbon filaments were ...
Diffraction spikes are lines radiating from bright light sources, causing what is known as the starburst effect [1] or sunstars [2] in photographs and in vision. They are artifacts caused by light diffracting around the support vanes of the secondary mirror in reflecting telescopes , or edges of non-circular camera apertures , and around ...
