Depth of Focus vs Depth of Field (DOF) – To clear up any confusion, these terms mean the same thing. They can be used interchangeably with focus range and DOF.
Smaller f-stop value = larger aperture diameter = smaller DOF
Larger f-stop value = smaller aperture diameter = larger DOF
- Depth of field or focus range is the distance between the closest and farthest objects in an image, both of which are in focus.
- All objects between these closest and farthest objects are also in focus
- The photographer can adjust the f-stop value, in turn, controlling the depth of field.
Smaller f-stop value = larger aperture diameter = smaller DOF
Larger f-stop value = smaller aperture diameter = larger DOF
