Aperture and Depth of Field

A large aperture will cause a shallow depth of field – only a small area will be in focus and the background will be blurry. The closer you are to the object you are taking, the blurrier the background will be, but also, the further the object is from the background, the background will be blurrier.

With a smaller aperture, you will get a larger depth of field and you will be getting most (if not all) the objects in focus.

On my Cannon camera, there is an option called A-Dep that allows me to see exactly what my camera will see at a chosen aperture so I can decide what will be in focus and what will be blurry, but I didn’t use it on this occasion.

My task for this week was to create four images:

Two showing a shallow depth of field, meaning only one point of the picture will be in focus.

Two showing a deep depth of field, meaning all or most of the image should be in focus.

I chose the following pictures:
