What is "Depth of Field"
Here are some links to articles on depth of field.
Here are two photo's which I took at different F stops. I focused both on the bird bath. See if you can see the difference with the depth of field. In one, the background is out of focus, where the other one it's in focus.
42mm ISO3200 F22 1/20
Depth of field is governed by three factors: aperture, lens focal length and shooting distance.
The smaller the aperture, the deeper the depth of field (the other two factors remaining the same). For example, if the lens focal length and the shooting distance stay the same, the depth of field is much deeper at f/16 than at f/1.4.
The shorter the lens focal length, the deeper the depth of field (the other two factors remaining the same). For example, comparing a 28mm lens with a 50mm lens at the same aperture and shooting distance, depth of field is deeper with the 28mm lens..
The greater the shooting distance, the deeper the depth of field. i.e. other two factors remaining the same). For example, if the subject is photographed from three and then from seven meters away, the zone of sharpness in the foreground and background is greater at seven meters.
