atmospheric perspective
a perspective device based on the observation that as objects recede in space, the effects of light and atmospheric dust result in values having less contrast in the distance.
linear perspective
a method of drawing developed in renaissance Italy that uses a horizon line and vanishing points to show that lines converge as they recede in space.
optical illusion that objects appear smaller as they recede in space.
regular oval shape; a circle becomes this when seen in perspective.
eye level
height of your eyes when looking at an object; you may be looking down, up, or directly at an object; in perspective drawing, this is the same level as the horizon line.
organization, arrangement of basic visual elements in a drawing, in relationship to each other and the whole.
compositional sketch
quick preliminary drawing to determine the organization of a picture; NOT detailed.
line quality
a variety of width, value, and activity in line that can be used for both descriptive and expressive purposes.
the line describing the outside edge of a form.
contour line
a line used to follow the edges of forms; this may be applied along, as well as within, the outer edges of a depicted form.
relative degree of lightness or darkness, black and white and all the grays in between.
the transition from light to dark to create spatial illusion.
a two dimensional area bounded by line or value or both (two main types: organic and geometric)
perceptual drawing
drawing primarily concerned with specific visual stimuli - what you SEE.
conceptual drawing
drawing primarily conceived in the mind of the artist - what you THINK.
subjective opinion
viewpoint primarily concerned with the personal, emotional response of the individual.
objective opinion
viewpoint primarily concerned with the factual information available.
positive space
the area in the drawing occupied by the shape of the object that serves as the subject of the drawing.
negative space
the remaining space surrounding the positive shape in the picture plane; the relationship of the positive to negative is also called the figure-to-ground relationship.
vertical and horizontal alignment
position with reference to vertical and horizontal axes - is something in your composition to the left, to the right, above, and below something else.
