1. We should closely relate the eyes to aperture. I said this because your pupils act like the lens of a camera when you are shooting because your peripheral vision and your vision in general act like a good indicator for what aperture is like.
2. The smaller the aperture, less light. The higher the aperture, more light or exposure.
3. The aperture effects the depth of field by how much focus is on the subject and how much is effects the depth of the image. For example, taking a photo with small aperture results in more focus and a little amount of blur in the background. It also effects the foreground and background focus.
