Effect of Aperture on Depth Of Field

Smaller the aperture size greater is the DOF. Which also means higher the f stop, higher the depth of field. F16 will produce greater DOF than F8.

Aperture Concept Illustrated

The higher the f-number, the smaller the aperture and the less is the light that passes through the lens. Opening one full f-stop doubles the amount of light. Closing down one full f-stop halves the amount of light passing through the lens and halves the brightness of the image that falls on the image sensor.

A for Aperture

Aperture is the size of opening for lens, which controls the brightness of the image that passes through the lens and falls on the image sensor. It is expressed as the F-stop, f/1.4, f/2, f/2.8, /f4, f/5.6, f/8, f/11, f/16, f/22, or f/32.
