Enter the distance to an object, the f-number, circle of confusion, and focal length into the calculator to determine the depth of field.

## Depth of Field Formula

The following formula is used to calculate a depth of field.

DOF = 2*u*N*c/f^{2}

- Where DOF is the depth of field
- u is the distance to the subject
- N is the f-number
- c is the circle of confusion
- f is the focal length

## Depth of Field Definition

A depth of field is defined as the distance between the nearest and furthest distance that are acceptably sharp focus in an image.

## Depth of Field Example

How to calculate a depth of field?
