Question

Can someone rewrite this in their own words please.
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.

Answer 1

Answer:

The open depth of field can be compared to an eye. Your eye contains an iris that either expands or contracts when exposed to certain amounts of light. It can be referred to as the aperture settings on your camera. A shallow depth of field is when a focus point of your picture is very clear, while other parts, such as the background, are blurred.
