Depth of field depends on the focus distance, while depth of focus does not. Depth of focus can have two slightly different meanings. The first is the distance over which the image plane can be displaced while a single object plane remains in acceptably sharp focus; [1][2] [clarify] the second is the image-side conjugate of depth of field.
The hyperfocal distance has a property called "consecutive depths of field", where a lens focused at an object whose distance from the lens is at the hyperfocal distance H will hold a depth of field from H/2 to infinity, if the lens is focused to H/2, the depth of field will be from H/3 to H; if the lens is then focused to H/3, the depth of ...

Most operating systems have a built in feature that allows you to take a picture of what is on your screen. If you're asked to provide a screenshot when contacting AOL about an issue, you can use these steps for the most common operating systems. If you're using a different device, contact the manufacturer of the device for specific steps.
The depth of field of an image produced at a given f-number is dependent on other parameters as well, including the focal length, the subject distance, and the format of the film or sensor used to capture the image. Depth of field can be described as depending on just angle of view, subject distance, and entrance pupil diameter (as in von Rohr ...
When the field of view is limited by a field stop in the lens (rather than at the film or sensor) vignetting results; this is only a problem if the resulting field of view is less than was desired. In astronomy, the opening diameter of the aperture stop (called the aperture ) is a critical parameter in the design of a telescope .
Deep focus is a photographic and cinematographic technique using a large depth of field. Depth of field is the front-to-back range of focus in an image, or how much of it appears sharp and clear. In deep focus, the foreground, middle ground, and background are all in focus. Deep focus is normally achieved by choosing a small aperture.
Focus stacking – also called focal plane merging, z-stacking, [1] or focus blending – is a digital image processing technique which combines multiple images taken at different focus distances to give a resulting image with a greater depth of field (DOF) than any of the individual source images.
