Terms Flashcards
Aerial Perspective
the disappearance of objects into the distance; they become smaller and less distinct. Values have less contrast far away,
Cast shadow
a dark edged shadow caused when an object blocks a light source, it softens and lightens as it extends away from the object.
Charcoal
vine charcoal is usually a birch or willow branches burned to carbon. Less permanent
Charcoal pencil
compressed charcoal encased in wood. More permanent
Chiaroscuro
subtle gradations from light to dark that usually imply form. We are practicing chiaroscuro in this class
Composition
orderly arrangement of individual parts into a coherent whole
Contour
edges found around and within an object, shown by a change of value, edges, color, ect.
contrast
the relative difference between examples of any one element ( size, value, texture, color, ect)
Ellipse
a circle in perspective
Emphasis
focus on one part of a form or composition through contrast or directional lines
eye level/horizon line
the level of the viewer’s eye in relation to the object. The horizon line is at eye level
five value scale
set of 5 values in a drawing that represents highlight, light, mid-tone, core/form shadow, and reflected light
form
an area, which is three-dimensional or has implied dimension
Graphite
a form of crystallized carbon, which is used of different elements
Harmony
the relationship between unity and variety: a unity of different elements
Highlight
where light source hits an object: the lightest area of an object
LIne
the path of a moving point
Linear Perspective
the appearance of depths or space through the use of converging lines
Lost and Found edges
edges may disappear when values are similar and reappear when values at edges are contrasted
Mass
three-dimensional bulk of an object
Modeling
creating an impression of 3 dimensional volumes through gradations of value or color in shading
Negative space
space around or enclosed by the positive shape/form
outline
the line describing the outside edge of an object; tends to be 2 dimensional
overlap
one shape covering part of another creating an illusion of distance or space
plane
a continuous flat surface
Proportion
size relationships between parts of a whole; part to part or whole-whole
Recede
to extend from near to far. A line or plane that starts near may extend far away
Reflected light
light bouncing back onto a shadowed object creating a light in the shadow area. Never lighter than the light
Refraction
the bending of light rays as they pass through transparent objects
Restatment
a line or lines used to correct a portion of the drawing without erasing the original incorrect line
shape
a 2-dimensional
Tangent
shapes that touch each other rather than overlapping, causing confusion of space. Commonly used for abstraction. Has a flattering effect
Texture
tactile quality of the surface such as rough, smooth slippery, ect
Unity
various parts of a composition working together as a whole
Value
the lightness or darkness of an object or area
Vanishing points
points at which receding lines converge in linear perspective on the horizon line
variety
the difference or contrast of elements
visual texture
the illusion of texture in a drawing or painting. AKA implied texture
