Allan Paivio's dual-coding theory is a basis of picture superiority effect. Paivio claims that pictures have advantages over words with regards to coding and retrieval of stored memory because pictures are coded more easily and can be retrieved from symbolic mode, while the dual coding process using words is more difficult for both coding and retrieval.
At the same time, techniques in art and design can open up pathways to stimulate the thought process and problem solving. Sketches offer an unrestrained way to get thoughts down on paper through the "abstract representations of ideas and idea structures". [ 27 ]
The maximum contrast of an image is termed the contrast ratio or dynamic range. In images where the contrast ratio approaches the maximum possible for the medium, there is a conservation of contrast. In such cases, increasing contrast in certain parts of the image will necessarily result in a decrease in contrast elsewhere.
Such elements can be of dramatic use in the composition of the image. These could be literal lines such as telephone and power cables or rigging on boats. Lines can also derive from the borders of different colors or contrast, or sequences of discrete elements. Movement is also a source of lines, where the blurred movement renders as a line. [1]
