	Basic Photography Techniques - Perspective.
		In other words, perspective in the composition of a photograph is the way real three-dimensional objects are pictured in a photograph that has a two-dimensional plane.
		When you know the principles of perspective and skillfully apply them, the photographs you produce show a good rendition of the subject's form and shape, and the viewer is given the sensation of volume, space, depth, and distance.
		The other false perspective is produced by a fisheye lens in which all straight lines in the subject are imaged as curved lines toward the edges of the picture.

	Using The Idea Of Atmosphere
		Atmospheric perspective is normally discussed in conjunction with landscape painting since its true effect is primarily seen in nature in conjunction with great distances in space.
		In this chapter, using the idea of atmosphere will be expanded upon to include its use as a basic element of design in the drawing to enhance the action of the figure and to clarify the three dimensionality of the form.
		The use of "atmosphere" in this illustration would generally be referred to as "just tone." The main point here is that the atmosphere around the figure is being manipulated as a compositional element to enhance the action.

		Although many periods in art showed some progressive diminution of objects seen in depth, linear perspective, in the modern sense, was probably first formulated in 15th-century Florence by the architects Brunelleschi and Alberti.
		Aerial or atmospheric perspective was developed primarily by Leonardo da Vinci.
		In East Asian art, perspective effects were achieved by the atmospheric method, often incorporating zones of mist to separate near and far space.

	Atmospheric (Aerial) Perspective: Art Studio Chalkboard (Site not responding. Last check: 2007-11-05)
		Aerial or atmospheric interference with visual perception causes loss of contrast, detail and sharp focus.
		Hint: As objects recede away from the viewer in atmospheric perspective, bright whites and rich fls tend toward medium gray and eventually disappear into a blue/gray background.
		Sometimes an artist describes aerial perspective by allowing the white, or color of the paper to dominate as the depth increases.

	Perspective Lesson for Visual Artists - Nancy Doyle Fine Art (Site not responding. Last check: 2007-11-05)
		Perspective is also a good thing for an artist to learn, even if their work is not concerned with realistic representation, for it teaches students about the element of space in two-dimensional art.
		As it is a mathematical theory, linear perspective is sometimes presented with a technical approach, with formulas and the language of geometry.
		The concept of atmospheric perspective is also described and illustrated, as are the subject areas of perspective in still life, the human figure and landscapes, including foreshortening and viewing circles and cubes in perspective.

	Painting Lesson: Aerial or Atmospheric Perspective (Site not responding. Last check: 2007-11-05)
		Many people have heard of linear perspective, which describes how the appearance of linear and boxy objects is altered by their distance from the viewer.
		Aerial perspective—also called atmospheric perspective—describes how the appearance of objects is altered over distance by the effects of the air between the viewer and the object.
		The farther away an object is, the thicker this imperfect "lens" of air is and the stronger the effect of aerial perspective.

	Atmospheric Perspective
		The phenomenons of atmospheric perspective and depth of field must be considered in working on this project.
		Aerial perspective is the portrayal of that atmospheric haze -- one means to adding to an illusion of depth in depicting space on a flat surface.
		It is achieved by using less focus, along with bluer, lighter, and duller hues for the distant spaces and objects depicted in a picture.

	The Oil Painter's Bible - chapter 5
		Geometric perspective, often referred to as simply perspective, may be defined as the natural law which says the further something is from our eyes, the smaller its image will be.
		Since there are two types of perspective, the other being atmospheric perspective, it is necessary to distinguish between them by referring to what is normally called perspective as geometric perspective, in reference to the fact that it is a geometric breakdown of a natural optical phenomenon.
		It is sometimes referred to as linear perspective, as it involves the use of lines in its construction.

	Module 1 Use
		Atmospheric perspective was first described and named by Leonardo da Vinci, who called it aerial perspective.
		Through the use of rational systems of perspective along with the emotional values created by the depiction of light and atmosphere, Renaissance artists were able to create afictive space in their landscapes and backgrounds that not only provides a convincing imitation of reality, but that evokes feelings of awe, wonder and pleasure in the viewer.
		Desktop 3D programs employ all three traditional techniques (perspective, chiaroscuro and atmospheric depth cues) as well as other monocular depth cues (occlusion, size differences and texture gradients) to create renderings that imitate reality, and in skilled hands 3D graphics can also be used to create images that touch the emotions.

	SPARROW - Atmospheric Nitrogen Flux from Watersheds of Major US Estuaries
		To assess the atmospheric contributions of total nitrogen (TN) in riverine exports to coastal and estuarine ecosystems in the United States, we applied a nationally calibrated empirical watershed model, SPARROW (Spatially Referenced Regression on Watershed attributes), to a selected set of 40 major coastal watersheds.
		The atmosphere is estimated to contribute from 4 to 35 percent of the TN in stream export with a median of 20 percent.
		Assessments of atmospheric sources to coastal watersheds are likely to benefit from a continued effort to integrate the mechanistic descriptions of deterministic models with the empirical methods of estimating watershed-scale rate processes and their uncertainties in statistical models.

	Perspective - GPN
		In art, perspective is often referred to as a "system of seeing," a way to help the artist create the illusion of three dimensions on a two-dimensional surface.
		Not all artists choose to use perspective, in fact, there are different cultures and different periods of art that are known for their lack of perspective.
		Basically, perspective is a tool that artists may use if they want their pictures to have depth and to look realistic.

	Using Tone To Draw
		In the beginning of this chapter, I mentioned that we will be discussing three distinct approaches, "indirect lighting, direct lighting, and atmospheric perspective," and that, in practice, we usually use all three methods together to various degrees.
		In that context, we are now going to use some of the basic elements of atmospheric perspective in conjunction with the modeling tone.
		The basic concept of atmospheric perspective is that the farther something is away from you, the more atmosphere there is between you and the form.

	Depth
		Atmospheric perspective - close objects have greater intensity of color, detail and value contrast.
		As an example of one-point perspective (there is also two- and three-point perspective), the diagonal lines converge on a single point on the horizon called the vanishing point.
		In one-point perspective, the horizontal and vertical lines are parallel with the sides of the image.

		Well, it is true, but the fact that the atmosphere scatters light also plays a role in our depth perception.
		The short or blue wavelengths of light are most easily scattered every whichway by the particles in the atmosphere which is why the sky is blue, although scattering does occur to some extent for other wavelengths of light.
		The far rim is less distinct, and less distinct than can be accounted for just because it is farther away, and the walls, made of the same material as the near side, have a decidedly bluish cast.

	Causes of Aerial Perspective
		Leonardo recognized that the atmosphere surrounding the earth contained moisture and dust as well as air.
		If it was, the sky overhead would appear bluer from lower elevations where the earth's atmosphere is thicker than from a mountain top where it is thinner.
		He concluded that the blue color of distant mountains results from warm water vapor in the air illuminated by sunlight in front of the dark background of the mountains.
