Aurora

Light collishes with charged particles. This creates a light in the sky, but it can be bands, spirals or beams of light that moves in the sky. The sensation of floating lights above you, lights moving as if you were flying in some mystical place. The changes of colours are magic.

Garbage and light merge into art.

Tim Noble (Stroud, 1966) and Sue Webster (Leicester, 1967) are two London artists to make sculptures with garbage collected from the streets of London. Original but not the material but how to project the light through the sculpture.



Piles of waste are in no apparent order, except when light shines on them from a particular point: on the wall then cast shadows that make the work itself.

Photography filters

The picture depends on the light. The incision, the quality and quantity of this changes the nuances of photography. Filters, color balance situations, retain the light spectrum and allow the passage of light only of the same color. The absorption of light in relation to the density of the filter is offset by the increased exposure.

The filters, which are crystals with different effects on the photography end. They are mounted in front of the lens by means of a screw thread called Portalibros and in some cameras with bayonet coupling. There is also a system that uses a universal framework that is coupled by a thread to the target. This is the Cokin system.


The filters can be classified in contrast to black and white, color protection, polarizer, of special effects and zoom lenses.

Three centuries before Leonardo da Vinci light arises not as an abstract concept but as a being intrinsically pictorial, as something that builds the composition, although not without meaning. His Virgin of the rocks combines mystery and a wise perspective on symbiosis of light and shapes that are themselves as prospects lines, deep lines, remote and cryptic.


1813-1814, The Third of May 1808, Francisco de Goya. Artificial light.
It creates a huge contrast to the terrifying scene appear bright in contrast to an almost completely black background. It increases the drama of the moment and amplifies the tragedy as another light intensity to detract from the image. The light from a lamp is particularly intense in the Spanish patriots ready to die, and specifically in the main character of white shirt and ocher pants with the arms raised. The light we underlines the strength and courage of this man, while the French firing squad appears in gray and faceless.
