 DoF decreases as magnification increases;
in a close-up photograph of a miniature scene, the DoF is limited, and it often is impossible to have everything appear sharp even at the lens's smallest aperture.Consequently, the foreground and background are often blurred, with the blur increasing with distance above or below the center of the image.In a photograph of a full-size scene, the DoF is considerably greater; in some cases, it is difficult to have much of the scene "outside" the DoF, even at the lens's maximum aperture.
