LESSON XXVII
PERSPECTIVE
It is very important for the student to understand something about perspective in order to be able to place chairs, tables, etc., in his drawings; rugs and squares on floors must be drawn according to rule. A few simple rules are here given to aid the student in the perspective needed in fashion drawing. Study these rules carefully and apply them when copying pictures.
When copying the chart, draw in large enough scale to enable you to work well; these illustrations are very small. Be very accurate as every fraction of an inch will tell. Use a ruler on all straight lines and a compass for circles.
There are two kinds of perspective, parallel (or one point) perspective, and angular (or two point) perspective.
The horizon (H) is an imaginary horizontal line, where earth and sky seem to meet; it is high or low according to the elevation of the observer.
Example. A person on a mountain can view more of the surrounding country than if he were on the level, hence the horizon will be high as it is directly on a line with his eyes.
Place your pencil across your eyes, if you can see just over the top you have the horizon line.
The point of sight (PS) is an imaginary point on the horizon directly in front of the eyes. The direction of vision is an imaginary line from the eye to the point of sight.
The picture plane is a vertical plane on which the picture is drawn.
The ground plane is the plane on which the observer stands.
The place he stands (S) is called the
