Depth effect

from Wikipedia, the free encyclopedia
Effect of depth:
Note that the screen is flat!

As depth in is painting , photography and other visual arts , the phenomenon of spatial effect called when viewing an area.

Basics

A 2-dimensional image appears as if there was an additional dimension. In addition to height and width, the third dimension appears to be depth. This effect occurs through the influence of light, color and the arrangement of lines. The depth effect of an image is based on an optical illusion .

Methods

The most important method for creating a sense of depth in images is perspective . First and foremost, this is the geometric perspective, which reproduces the laws on which mapping to the eye as a “technical device” is based. Spatial perspective is based on the shortening of lines.

In addition, artistic illustrations also use perspectives that insist on contrasts in the painting surface, such as the color perspective and the aerial perspective . In the artistic representation, large and transverse elements in the foreground of the picture also reinforce the spatial effect of depth.

Another method is the shadow effect via light-dark or warm-cold contrasts, which has been known since ancient times and has been used masterfully by numerous painters throughout history. It can also be used in modern image processing to create a depth effect on the screen ( shading ).

Since the invention of photography , another method has been added that was only rudimentarily used in classical painting, that is the effect of depth via blurring :

  • the depth of field , which mimics the remote adjustment ( accommodation ) of the eye and results from imaging problems
  • the soft focus as an artistic effect that uses the depth effect on a more psychological aspect from a distance, up to transfiguration

  • Early attempt at a spatial perspective : Diebold Lauber's
    workshop , around 1450

  • Aerial and color perspective : hilly landscape in haze

  • Shadow effect:
    shading with POV-Ray

  • Depth of field:
    The depth effect of narrowly limited depth of field is enormous

  • spatial depth effect as an urban design means, by means of visual axis and point de vue ; Lindenallee, Weissenbach an der Triesting
