DEPTH OF FIELD- Means how much an image is in focus.You can have a narrow depth of field, where only a small part of the image is in focus, or you can have a larger depth of field, where everything is in focus.
Two main aspects of depth of field are, Aperture and Focus Points.
Focus Points - Its basically where you set the main focus, normally its set to the middle, but it can be moved around.
Aperture - A large f-number such as f/32, (which means a smaller aperture) will bring all foreground and background objects in focus, while a small f-number such as f/1.4 will isolate the foreground from the background by making the foreground objects sharp and the background blurry.
- A camera can only focus its lens at a single point, but there will be an area that stretches in front of and behind this focus point that still appears sharp.
- This zone is known as the depth of field. It's not a fixed distance, it changes in size and can be described as either 'shallow' (where only a narrow zone appears sharp) or deep (where more of the picture appears sharp).
