Aperture

F2.8


F16

1. We can relate the human eye to the aperture, every camera that we know of today is designed like human eyes.

2. The smaller the Aperture a smaller f-stop, the higher the Aperture larger f-stop.

3.  If the aperture is small it brings all the object in foreground and background in focus, while a bigger aperture means the background is sharp and the object are clad and isolated from the background.
