Shade

Shade is the blocking of sunlight (in particular direct sunshine) by any object, and also the shadow created by that object. It may refer to blocking of sunlight by a roof, a tree, an umbrella, a window shade or blind, or anything else.

Shade is an important issue in temperate and tropical zones for providing cooling and shelter from the sun. Providing certain configurations of shading is an important passive solar technique. This may be done with overhangs, with shade trees, or with vines.

Shading using non-living materials blocks the sun, but also results in sunlight being absorbed and re-radiated as heat, or in sunlight being reflected as glare. Green plants, on the other hand, not only absorb a significant portion of the sunlight to invest as energy in photosynthesis to produce sugar, but also actively transpire, producing an additional cooling effect.

Example of shading.Shading is a process used in drawing for depicting levels of darkness on paper by applying more pressure with a drawing implement for darker areas, and less pressure for lighter areas. There are various techniques of shading including cross hatching where perpendicular lines of varying closeness are drawn in a grid pattern to shade an area. The closer the lines are together, the darker the area appears and vice versa.

Light patterns, such as objects having light areas and shaded areas, help when creating the illusion of depth on paper and on computer screens.

A Shade in the esoteric or spiritual sense can be one of many things. A spiritual or emotional imprint left on a person, place or thing. A "presence" that which is seen out of the corner of the eye or known (sometimes physically felt) only under conditions and times. They can come in many forms, anything from a deceased (or living for that matter) person's or animal's imprint left on something or someone, to something invoked into the "possession" of an object and even sometimes a person.
