Due to similarity in name and nature, depth of field (DOF) and depth of focus are commonly confused concepts. To simplify the definitions, DOF concerns the image quality of a stationary lens as an object is repositioned, whereas depth of focus concerns a stationary object and a sensor's ability to maintain focus for different sensor positions, including tilt. Close-up photography is quite demanding in terms of depth of field. The objects of interest (e.g., flowers, butterflies) have greater depth compared the distance to the object than most more distant objects. It is therefore desirable to use high f-numbers for closeup photography. There is a limit to how high you can make the effective f-number. The maximum depth of field that the graph will show is 10 meters (33 feet); depth of field approaches infinity at the hyperfocal distance for each aperture. The minimum distance is 4 times the focal length. What is Depth of Field? Depth of field is the distance between the closest and farthest objects in a photo that appears acceptably sharp. Now your camera can only focus sharply at one point. But the transition from sharp to unsharp is gradual, and the term 'acceptably sharp' is a loose one! The depth of field is defined as the distance between the nearest and farthest object planes that are both in focus at any given moment. In microscopy, the depth of field is how far above and below the sample plane the objective lens and the specimen can be while remaining in perfect focus. It is the axial or longitudinal resolving power of the How to use the Advanced Depth Of Field Calculator. Most depth of field calculators you find online give DoF values based on an accepted Circle of Confusion (CoC). This CoC results from the combination of the selected camera sensor and the following viewing hypothesis: Print size of 8''×10'' (20cm×25cm). Viewing distance of 10" (25cm). .
