In art, chiaroscuro ( English: / kiˌɑːrəˈsk ( j) ʊəroʊ / kee-AR-ə-SKOOR-oh, -SKURE-, Italian: [ˌkjaroˈskuːro]; lit. 'light-dark') is the use of strong contrasts between light and dark, usually bold contrasts affecting a whole composition. It is also a technical term used by artists and art historians for the use of contrasts of ...
At the same time, light is intrinsically found in painting, since it is indispensable for the composition of the image: the play of light and shadow is the basis of drawing and, in its interaction with color, is the primordial aspect of painting, with a direct influence on factors such as modeling and relief.

Glare (vision) Glare is difficulty of seeing in the presence of bright light such as direct or reflected sunlight or artificial light such as car headlamps at night. Because of this, some cars include mirrors with automatic anti-glare functions and in buildings, blinds or louvers are often used to protect occupants.
A dazzler is a non- lethal weapon which uses intense directed radiation to temporarily disorient its target with flash blindness. They can effectively deter further advances, regardless of language or cultural barriers, but can also be used for hailing and warning. [1] Targets can include electronic sensors as well as human vision.
Mathematicians have created a model that explains—and mimics—how fireflies flash in synchrony.
Scintillating scotoma is a common visual aura that was first described by 19th-century physician Hubert Airy (1838–1903). Originating from the brain, it may precede a migraine headache, but can also occur acephalgically (without headache), also known as visual migraine or migraine aura. [4]
Moving streaks of light wash across the pavement or walls in front of the car like a glittering snowstorm. But, while driving, the lights work just like standard high beam, low beam headlights.
Luminous intensity. In photometry, luminous intensity is a measure of the wavelength -weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye. The SI unit of luminous intensity is the candela (cd), an SI base unit .
A laser weapon [2] is a type of directed-energy weapon that uses lasers to inflict damage. Whether they will be deployed as practical, high-performance military weapons remains to be seen. [3] [4] One of the major issues with laser weapons is atmospheric thermal blooming, which is still largely unsolved.
