Let f be the lens focal length, N be the lens f -number, and c be the circle of confusion for a given image format. The H hyperfocal distance is approximately given by: $$\large H\approx\frac{f^2}{Nc}$$

, miosis). DOF formulas The basis of these formulas is given in the section Derivation of the DOF formulae; [10] refer to the diagram in that section for illustration of the quantities discussed below. Hyperfocal distance <span>Let be the lens focal length, be the lens f -number, and be the circle of confusion for a given image format. The hyperfocal distance is given by Moderate-to-large distances Let be the distance at which the camera is focused (the "subject distance"). When is large in comparison with the lens focal length, the d
