Depth of field (produced in the background of photo)
A camera can only focus its lens at a single point, but there will be an area that stretches in front of and behind this focus point that still appears sharp.

This zone is known as the depth of field. It痴 not a fixed distance, it changes in size and can be described as either 壮hallow� (where only a narrow zone appears sharp) or deep (where more of the picture appears sharp).
The focal length of the lens does appear to have a significant impact on depth of field, with longer lenses producing much more blur.
The reason longer lenses appear to produce a shallower depth of field is thanks to their narrow angle of view: compared to a wide lens, a telephoto will fill the frame with a much smaller area of background, so any blur appears magnified too.
