In your own words define 'Open Depth of field ' and ' shallow depth of field '

Open Depth of field is controlled by changing the aperture setting on your camera. Like your eye, a camera lens has an iris inside that can open or close to let in more or less light. A shallow depth of field is the small or narrow area in an image that is in focus. Often, the background is blurred while only the subject stays in focus.
