Что (кто) такое hyperfocal distance - определение


hyperfocal distance         
¦ noun the distance between a camera lens and the closest object which is in focus when the lens is focused at infinity.
Hyperfocal distance         
In optics and photography, hyperfocal distance is a distance beyond which all objects can be brought into an "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 camera.
Distance         
  • The distances between these three sets do not satisfy the triangle inequality:<math display="block">d(A,B)>d(A,C)+d(C,B)</math>
  • Distance along a path compared with displacement.  The Euclidean distance is the length of the displacement vector.
  • Airline routes between [[Los Angeles]] and [[Tokyo]] approximately follow a direct [[great circle]] route (top), but use the [[jet stream]] (bottom) when heading eastwards. The shortest route appears as a curve rather than a straight line because the [[map projection]] does not scale all distances equally compared to the real spherical surface of the Earth.
