Definition: This explains how deep the focus is within an image and is controlled by the aperture/F-Stop. Images with a large amount of the image in focus are said to have a large depth of field while images with only one small part in focus are said to have a small depth of field. This does not affect the side to side focus of the image, only the depth.
