Depth of Field

1. Depth of field is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. 
2. The difference between a small and large depth of field . A small depth of field is when only a small part of the image is in focus. A large depth of field is when a large area of the picture is in focus.
3. My image shows depth of field because only a small part of the image is in focus and the rest is blurry.
