Term | Definition |
---|---|
perspective | a technique used to create the illusion of 3D space and objects on the two -dimensional surface of a picture plane. |
who developed the technique of perspective? | architect Filippo Brunelleschi. |
perspective is created by... | overlapping, size variations, placement, detail, color and converging lines. |
what is the basic rule of perspective? | objects appear to grow smaller as they recede, and lines which in reality are parallel, meet at a point on the horizon |
perpective drawing | a drawing on a 2D surface that gives the illusion of 3D space and objects |
picture plane | the actual 2D surface on which the painting or drawinf is made |
Linear perspective | the technique used to create the illusion of distance and depth on a 2D surface |
Horizon line | the line at which the earth and sky meet |
Vanishing point | in linear perspective, the point on the horizon line at which all the receding parallel lines converge |
convergence | in linear perspective, the point at which parallel lines meet as they recede. |
line | the path of a point moving through space is a line |
shape | the edge of something 2D |
form | the 3D shape of something |
value | the gradations between light and dark. |
texture | the quality of surface or the illusion of surface |
space | actual space bounded or manipulated by architecture or sculpture or the illusion of space on a 2D surface. |
negative space | empty, white space |
positive space | colored spaces |
color | color is caused by the differing qualities of light reflected or emitted. |
primary colors def. | colors that cannot be made by mixing other colors. |
secondary colors | colors made by mixing two primary colors |
list of primary colors | red, yellow, blue |
list of secondary colors | orange, green, purple. |
blind contour line drawing | a line drawing created without looking at the paper. |
contour | another word for line; the outermost edge of a subject. |
contour drawing | style of drawing which uses outlines to define the subject. |
purpose of blind contour and contour line studies | it teaches you how to see; it trains your eyes to look at the subject |
continuous line drawing | drawing created without lifting the pencil off of the paper. |
modified contour drawing | a contour drawing in which the artist is able to look at the paper and lift the pencil. |
the different types of contour line drawings | contour, blind, continuos, modified. |
mid tone | the tone that is midway in between the highlight and the shadow |
reflected light | light cast on a form after being reflected from another form |
shadow | the darkest area on the surface of the object; the area of a represented shape that receives the greatest amount of direct light. |
cast shadow | the dark tones resulting on a surface from the blocking of light rays by a solid object. |
highlight | the lightest value on a form; the area of a represented shape that receives the greatest amount of direct light. |
value | the relative degree of lightness or darkness given to an area by the amount of light reflected from it. |
chiaroscuro | the use of light and dark to create the illusion of 3D form. |
how many colors in the color wheel? | 12 |
tertiary colors | made from combining one color with one secondary color (green blue, red orange, purple red, etc) |
complementary colors | colors across from one another on the color wheel (yellow and purple, green and red, blue and orange) |
analogous colors | colors side by side on the color wheel |
hue | a color |
tint | a color + white = tint |
shade | color+black= shade |
