Introduction
Perspective is a subject that helps we draw third dimension objects on a flat surface
like the image when we look at the objects in real life. Perspective drawing is
concerned with achieving a sense of space, of depth and of the third dimension,
within the limits of the flat drawing surface.
We can use the rules of
perspective in sketching,
finding ideas and creativity
in designing

PERSPECTIVE
How do we see the objects in real life ?
1. Diminution
Objects appear smaller as their distance from the observer increases
For example, someone across the street appears smaller than the person next to you, someone
down the street appears still smaller, and so on.

2. Foreshortening
Line or surfaces parallel to the observer's face show their maximum size. As they are
revolved away from the observer they appear increasingly shorter

3. Convergence
Lines or edges of objects which in reality are parallel appear to come together (i.e.,
converge) as they recede from observer

4. Overlapping
Our eyes can see objects which are in the front or in the back.
Overlapping is a very important technique of achieving a sense of depth and space in
drawings

5. Shades and shadows
The shape and structure of three- dimensional objects can be understood only when
viewed in some form of light.

6. Color and value perspective
Values (black to white range) and
colors are bright and clear when
seen close up but become
grayer, weaker, and generally
more neutral as their distance
from the observer increases.
These principles are rarely
discussed in perspective
books yet they suggest useful
techniques for increasing the
sense of depth and space in a
drawing

7. Focus Effect
The eye looking at a distant object will focus at that object's range; things in the
foreground, consequently, will be "out of focus" and therefore blurred.
