this sense of depth. There are a few important
methods that go into its formation; these are:
positioning one object on top of another, the
perspective of atmosphere, texture, linear
perspective, dimension, height and
movement. I brought some pictures to
illustrate this.

MURAD: Putting images one on top of the
other is an important method of creating the
sense of depth. Ahmed, it's your turn for an
experiment. Now, take one of these two pens in one hand and one in your
other hand. Hold them a little distance from your eyes but don't put them
on top of each other. Now, move one pen a little farther away and close
one eye. Without looking with both eyes, it's very difficult to know which
one is farther away, isn't it?

AHMED: Yes, you're right.

MURAD: Now, with one eye closed, bring the two pens close
together and place one in front of the other. Now you can measure space
and depth much better, can't you?

AHMED: True.

MURAD: The famous American psychologist James J. Gibson was
one of the first to understand the importance of change of texture in the
sensation of depth. The surface we walk on, a road, or a field full of
flowers is actually a texture. The textures close to us are more detailed
while those more distant appear indistinct. For this reason, it is easier to
make a judgment about the distance of an object which is placed on a
texture.
