Depth of Field

                                                The area in front of the camera that appears sharp in the frame is called depth of field. Depth of Field is defined as the range of acceptable focus on a shot. Depth of field is an important concept for cinematographers and camera operators to master because they often need to manipulate focus to achieve a desired effect. 

Depth of field can be either shallow or deep. Shallow depth of field is the kind in which part of the frame is soft or out of focus. Thus, the areas of focus or sharpness are limited. Deep depth of field, on the other hand, is the kind in which the entire frame, from the foreground to the background, is sharp or in focus.
Three factors affect depth of field:
  1. Aperture
  2. Focal length
  3. Focus distance
