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 .
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 ...
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".
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.

Access to Nature. Whether through large windows, balconies, porches, or yard space, biophilic design prioritizes access to nature. In largely urban areas or high rises, this can take the form of ...
In addition to its unique depth of field properties, the Frazier lens is significantly smaller than previous deep focus lenses allowing more versatility and flexibility to cinematographers. The main feature of the lens, an extended tube with a rotating prism , allows cinematographers to place the camera in a variety of positions for a given shot.
