“Depth of field (DOF) is the distance in front of and beyond the subject that appears to be in focus. There is only one distance at which a subject is precisely in focus, but focus falls off gradually on either side of that distance, and there is a region in which the blurring is imperceptible under normal viewing conditions.” – Wikipedia

DOF field varies with aperture, from shallow at wide aperture (foreground and background blurred), to infinite at small aperture (Pinhole Camera Effect).

Note: Wide aperture (shallow DOF) is represented with a smaller f/stop while a smaller aperture (deep DOF) is represented with a larger f/stop.
