The opposite of deep focus is shallow focus, in which the plane of the image that is in focus is very shallow. [1] For example, the foreground might be in focus while the middle-ground and background are out-of-focus. When avoiding deep focus is used specifically for aesthetic effect—especially when the subject is in sharp focus while the ...
A deep-focus earthquake in seismology (also called a plutonic earthquake) is an earthquake with a hypocenter depth exceeding 300 km. They occur almost exclusively at convergent boundaries in association with subducted oceanic lithosphere .
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) are classified as shallow-focus earthquakes, while those with a focal depth between 70 km (43 mi) and 300 km (190 mi) are commonly termed mid-focus or intermediate-depth earthquakes.

Gregg Wesley Toland (May 29, 1904 – September 28, 1948) was an American cinematographer known for his innovative use of techniques such as deep focus, examples of which can be found in his work on Orson Welles' Citizen Kane (1941), William Wyler's The Best Years of Our Lives (1946), and John Ford's The Grapes of Wrath, and The Long Voyage Home (both, 1940).
Focus The optical clarity or precision of an image relative to normal human vision. Focus in photographic images is usually expressed in terms of depth. Framing The placement of subjects and other visual content with respect to the boundaries of the image. Hand-held shot A shot where the camera is hand-carried, either with or without a ...
Deep-focus earthquakes occur at a depth where the subducted lithosphere should no longer be brittle, due to the high temperature and pressure. A possible mechanism for the generation of deep-focus earthquakes is faulting caused by olivine undergoing a phase transition into a spinel structure.

For cameras that can only focus on one object distance at a time, depth of field is the distance between the nearest and the farthest objects that are in acceptably sharp focus in the image. [1] "Acceptably sharp focus" is defined using a property called the "circle of confusion".
