2.  Creates the illusion of space and distance on a flat surface (i.e.: a painting, photograph or sketch).  Lines that would be parallel in the real world meet in the two-dimensional picture to create depth.  Developed in the 1400’s during the Renaissance by artist and architect Filippo Brunelleschi.

4. Objects are seen head-on and are drawn to a single vanishing point.

5.  Parallel lines converge (or meet) at one point in the distance.  The point where these lines meet is called the “vanishing point.”

8. Objects seen at an angle would be drawn in two-point perspective using two vanishing points. Note: Artwork with two- point perspective often has vanishing points "off the page".

19.  Size : objects appear smaller as they get farther away.  Position : objects appear higher on the page as they get farther away.  Overlap : Overlapping objects show those in front are closer.  Detail : Objects have less detail as they get farther away.  Saturation of color : Close objects are brightest and sharpest. Objects in the distance appear pale and washed out.  Atmospheric perspective: Objects in the distance appear bluish.  Warm colors advance/cool colors recede : Warm colors appear closer. Cool colors appear farther away.
