Convergence (graphic)
Convergence (Latin: convergere , to lean towards, to approach, to converge) describes in the graphic the convergence of (optical) lines. These lines are seldom integrated directly into the picture as such. Their course results from the composition of the pictures and the individual motifs in the picture. Background, middle and foreground relations can also be structured by convergent lines. In this sense, convergent lines act as a visual design element. They are therefore mainly used in working practice in media communication .
function
Optical parallel lines, such as rows of windows on a house facade or the facade of a high-rise building, where you look upwards, converge with increasing distance and finally intersect at the so-called vanishing point . From here the crossed lines run divergent . With the help of such lines, a perspective impression can be created in graphic representations or intensified in photographic images. This image effect is additionally increased by a lower camera position. The effect of convergent (or divergent) lines is also used effectively in audiovisual formats.
Mode of action
Visual convergence is defined in two properties: clarity and simplicity . The clarity lies in the precise shape of straight individual elements: Lines are pragmatic, pointing the way and, thanks to their continuous form, can be clearly grasped. In its simplicity , this clarity is simply doubled: The overall construction draws an artistic composition ( triangular composition ) from two convergent straight lines , which can also offer an exciting perspective. In addition, the symmetry and the similarity of the forms give an impression of how the individual elements belong together . Then long-term memory is dug until one finds a memory that fits this pattern. Many people think of a road that runs towards the horizon. Consequently, the convergence also has an iconic or iconological potential for meaning. Quite often a subjective note can inspire the mind and stimulate creativity.
Application in practice
The effect of convergent lines lies in their strongly directional character. Since the observer tends to orient his gaze on continuous lines, convergent lines are important in many areas of media communication. For example, it makes sense to place the most important picture element, such as the eye-catcher of an advertising poster, in the area of the vanishing point, since the lines initially draw the eye to it. Only then is it forwarded and finally captures the image as a whole.
