DoF

The camera-like DoF display allows you to set parameters by pointing and dragging and immediately shows the results. Its unique double-cone display illustrates blur as a function of the subject's distance.

DoF takes diffraction into account

Unlike most other calculators, DoF determines the depth of field by taking into account both diffraction and the blurring caused by focusing. Diffraction can be a significant factor, especially with newer high-resolution digital cameras that have smaller sensors.

DoF calculates aperture values

Like most other calculators, DoF can calculate depth of field based on the aperture and focusing distance for a given lens. Even more useful, however, is that for a given range of distances, DoF can determine the aperture value and focusing distance that will provide the sharpest image when diffraction is taken into account, as well as what the worst-case blur will be.

DoF supports macro photography

Standard depth-of-field equations do not work for macro photography—DoF has a Macro mode that allows you to determine the depth of field by measuring the field of view at a distance from the subject. It then calculates the magnification from the field of view and the depth of field from the magnification.

DoF handles focus stacking

DoF has a Focus Stacking mode that shows you how to increase the depth of field by combining multiple images focused at different distances.

DoF handles blur

DoF can tell you exactly how much blur your images will have at each distance. The reference guide includes a set of images that illustrate what different levels of blur actually look like.
