Aperture

F2.8

F16

1. What part of the body should we closely relate to aperture?

The eye/pupil.

2. The smaller the Aperture the darker and more large depth of field. The higher the Aperture, the lighter and more shallow depth of field.

3. In your own words tell me how aperture impacts depth of field?

Aperture can make the depth of field thinner or more large. It can make the subject the whole photo, or more obvious by blurring the background.
