Line is one of the main components of design including principles such as shape, color, texture, value, perspective, and form. Lines can appear in many different forms some examples may be straight or curved; continuous or dotted; thick or thin; and real and implied. Line can be used to create structure and tone in illustrations and other artworks.
Ehrenstein carried out variations of the original illusion to test out how the strength of perception can change. In one variation, he changed the thickness of the lines. He found that the lines could be made very thin, and the illusion would still remain. The brightness of the centre increases with the thickness of the lines.
Line art or line drawing is any image that consists of distinct straight lines or curved lines placed against a background (usually plain). Two-dimensional or three-dimensional objects are often represented through shade (darkness) or hue . Line art can use lines of different colors, although line art is usually monochromatic.
An example of the Ponzo illusion. Both of the horizontal yellow lines are the same length. The Ponzo illusion is a geometrical-optical illusion that takes its name from the Italian psychologist Mario Ponzo (1882–1960). Ponzo never claimed to have discovered it, and it is indeed present in earlier work.
In the Müller-Lyer illusion, the visual system would in this explanation detect the depth cues, which are usually associated with 3D scenes, and incorrectly decide it is a 3D drawing. Then the size constancy mechanism would make us see an erroneous length of the object which, for a true perspective drawing, would be farther away.
Elements of art are stylistic features that are included within an art piece to help the artist communicate. [1] The seven most common elements include line, shape, texture, form, space, color and value, with the additions of mark making, and materiality.
The Rubin vase faces–vase drawing that Danish psychologist Edgar Rubin described [8] [9] exemplifies one of the key aspects of figure–ground organization, edge-assignment and its effect on shape perception. In the faces–vase drawing, the perceived shape depends critically on the direction in which the border (edge) between the black and ...
The psychology of art is the scientific study of cognitive and emotional processes precipitated by the sensory perception of aesthetic artefacts, such as viewing a painting or touching a sculpture. It is an emerging multidisciplinary field of inquiry, closely related to the psychology of aesthetics, including neuroaesthetics .
