Depth of focus is a lens optics concept that measures the tolerance of placement of the image plane (the film plane in a camera) in relation to the lens...

The depth of field (DOF) is the distance between the nearest and the furthest objects that are in acceptably sharp focus in an image captured with a camera...

In seismology, the depth of focus or focal depth is the depth at which an earthquake occurs. Earthquakes occurring at a depth of less than 70 km (43 mi)...

at different focus distances to give a resulting image with a greater depth of field (DOF) than any of the individual source images. Focus stacking can...

regions of an image which are outside the depth of field. The opposite of bokeh—an image in which multiple distances are visible and all are in focus—is deep...

accommodation. Multifocal IOLs can also be Trifocal IOLs or extended depth of focus (EDOF) lenses. As of 2021, nearly 28 million cataract procedures take place annually...

"acceptable" focus. As the hyperfocal distance is the focus distance giving the maximum depth of field, it is the most desirable distance to set the focus of a fixed-focus...

amount of blur of the considered object, whereas "depth from focus" (DFF) approaches tend to compare the sharpness of an object over a range of images taken...

the world in three dimensions. Depth perception happens primarily due to stereopsis and accommodation of the eye. Depth sensation is the corresponding...

Shallow focus is a photographic and cinematographic technique incorporating a small depth of field. In shallow focus, one plane of the scene is in focus while...

is the depth of focus. For a depth of focus of 100 nm, a small local deviation from flatness of 2.5 mrad (0.14°) can lead to a pattern shift of 1 nm. Simulations...

to have the entire subject in focus without the use of tilt or swing; consequently, the image must rely on the depth of field to have the entire subject...

the depth of field (depth of focus) of a 2 dimensional representation of a Lytro image to be adjusted after a picture has been taken. Instead of setting...

capability of Digital Holography in amplitude and phase it is possible to extend the depth of focus in microscopy. The digital analysis of a set of holograms...

lower f-stops narrows the range of focus so the background is blurry while the foreground is in focus. This depth of field increases as the aperture closes...

lens. Focus bracketing is useful in situations with limited depth of field, such as macro photography, where one may want to make a series of exposures...

"acceptable focus" (only one exact plane of the image is in precise focus) on the film or video target. Depth of field (not to be confused with depth of focus) is...

that of a fish eye, with a globular lens that has a depth of focus from 3 cm (1.2 in) to infinity. The image is focused by changing the position of the...

which increases depth of field so that though the different wavelengths focus at different distances, they are still in acceptable focus. Transverse CA...

Visual focus depth art s a form of mixed media collage that places an emphasis on the use of three-dimensional application to individual creations of single...

spatial depth. Selective focus in photography is usually associated with depth of field. A pinhole camera generates an image of infinite relative focus, from...

focal distance. Focusing information such as presented on a screen leads to a change in the depth of focus. This causes blurring of information presented...

the pupil constricts to increase the depth of focus of the eye by blocking the light scattered by the periphery of the cornea. The lens then increases...
