For instance: “Be careful when driving, the glare makes vision difficult”, “The glare caused by the explosion did not let me see for a few moments”, “It must be a zero kilometer car: look at the glare from its roof”.

The notion of radiance is also used symbolically to refer to the gloss, the brilliance, the glare or the splendor of something or someone: “The glare of the last championship that the club won allowed to hide, for a time, the financial mismanagement”, “García Márquez will always enlighten us thanks to the glow of his books”, “The artist abandoned his career when he was still enjoying the glow of his most successful album”.

“The glow”, on the other hand, is the title of a novel written by American Stephen King and published in 1977. In his third book, King tells the story of Jack torrance, who settles with his family in a hotel located on a mountain to work as a caregiver.

RadianceIn the field of design graphic, glow can be an effect applied to an image to simulate that it emits light. Each application allows to achieve this in different ways, both through a certain series of steps and with tricks that arise from the creativity of each user. Photoshop, Gimp Y Paint.net are three examples of programs that organize your documents in layers, which is ideal to achieve this effect, since in the first place it is necessary to have the object (s) cut out to their contours, so that the brightness is located above the background.

Three-dimensional graphics often give glow the name of halo, a property of materials that makes them issuers of light. Unlike photography, where the product is static, 3d is often used to create animations, and the calculation of effects like this requires very powerful hardware, depending on the degree of realism and precision to be achieved.

Lighting is one of the most complex topics in graphics by computer, since it encompasses a series of highly demanding concepts from the point of view of processing; If an object that moves throughout the scene emits a glow, then it becomes necessary to calculate in each frame the effect that this produces in the others, with their corresponding shadows and dynamic reflections.

To create the feeling that a three-dimensional scene is being photographed by a real camera, it is possible to combine the halo (which must match the light source) and the flare (a linear sequence of illuminated points originating from the glare and pass through the center of the image, and may extend to the right or left, depending on the position of the camera). This can also apply to a picture static making use of design tools such as those mentioned above.
