Depth of field is the term used to describe the areas before and beyond the point of focus that also appear sharp. You can control how large this area is through your choice of aperture and lens. An image can be totally transformed by using a wide aperture such as f/2.8, which will throw a boring or messy background out of focus.

Changing your lens can create a different sense of perspective in your digital images. The relationship between the objects depends on which lens you are suing and where you position yourself.

Switching to a telephoto lens can exaggerate the effects of a shallow depth of field and enable you to make a subject pop out of a busy scene.

Also, a different viewpoint and a quick change of lenses is all yiu need to merge the foreground with the backgroubnd and create the illusion that the distant object are actually a ot closer.
