Chapter 13: Line Harrold, South Dakota Lines serve to define length, distance and shape, indicating boundaries and separate forms, textures and colors that move the eye and create the illusion of depth—like railroad tracks to the horizon. Physically, they can be many or few, take many shapes, have thickness and depth, length and texture with […]
Chapter 10: Gradation Aesthetically speaking, “gradation” refers to a gradual or graded change of tone over a surface. Artists refer to it as a grading of “values.” In color photography, gradation can be a transition from one hue to another or to a different level of saturation or brightness. In black and white, it’s the […]
Chapter 7: Depth of Field “Depth of field” (DOF) is the optical property of a photographic lens that determines the degree of sharpness between objects close to the camera and those farther away. When both distances, near and far, are sharp the DOF is said to be “long” or “deep.” When only the point of […]
We move in the direction of our beliefs Life isn’t ever a straight line on a single track. Rather, it’s a progression along many tracks with lots of switching going on. Although I have switched “tracks” purposefully, there were many instances, probably more, where a switch occurred and I didn’t see it coming. The analogy […]
By our works we are known Blunt, South Dakota When I photographed these orderly rows of young corn extending to the horizon, I was thinking about the farmer and his work, evidenced by the tractor tracks and the amount of time, money and energy it took to plant this enormous field. Reflecting on the image […]
All forms of life have value in themselves; equal right to grow and flourish Cultural historian and ecotheologian Thomas Berry distinguished between “shallow” and “deep” ecology. He said the former is based on the belief that big ecological problems can be resolved within an industrial, capitalist society by fighting pollution and resource depletion in order […]
Evolution’s main principle for survival One of Darwin’s principles of evolution became popularized in the phrase “survival of the fittest.” The problem with memorable slogans like this is that they simplify complex phenomena. In this instance, Darwin’s observations were correct, but his interpretation missed the mark. Scientists now understand that “fitness” does not necessarily mean […]
Depending on the species, daisies can be white with a yellow center, purple with a brownish center, red with a yellow center, orange with a yellow center, pink with a yellow center, yellow with a dark red center or blue with a green center. Part of the sunflower family and more than 4000 years old, […]
Soils are “living” systems—a combination of ground minerals and organic matter that began to form in the Cambrian Explosion (550 mya) after a mass extinction of life-forms between the Permian and Triassic geologic periods. Today, soils are to the land what plankton are to the oceans—the bottom or ground of the food chain. On average, […]
This is the 6th in a series of postings on the theme of whole systems thinking. The whole system’s principle of “equifinality,” a term coined by the father of systems theory, Ludwig von Bertalanffy, holds that in open systems, for those that have external interactions, a given end state can be reached by many […]
