WHAT IS APERTURE?
Aperture is the adjustment of how much light is allowed to pass through the lens. When there is a large hole through the lens it lets more light pass through and when there is a smaller hole, less light can pass through the lens.
WHAT IS DEPTH OF FIELD?
Depth of field is how much of the image you have photographed is in focus. It is the distance between the nearest and furthest photos which are “acceptably in focus” in an image captured with a camera.
Amy you explain well how aperture and depth of field works, but explain also how aperture settings affects depth of field. For example a large aperture f/2.8-f5.6 creates a narrow DoF and a small aperture f/16-f/29 creates a wide DoF
