  2. Depth of field - Wikipedia

    en.wikipedia.org/wiki/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 ...

    en.wikipedia.org/wiki/Digital_camera_modes

    DEP: [3] DEP (DEPth of field) mode, on some Canon cameras, set the aperture to yield the desired depth of field: one point at the nearest object that one wants to be in focus, half-presses the shutter, then points at the farthest object that one wants to be in focus, half-presses the shutter, at which point the camera sets both focus and ...

    Minox LX camera with hyperfocal red dot Nikon 28mm f /2.8 lens with markings for the depth of field. The lens is set at the hyperfocal distance for f /22.The orange mark corresponding to f /22 is at the infinity mark (∞).

  5. Deep focus - Wikipedia

    en.wikipedia.org/wiki/Deep_focus

    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. Since the aperture of a camera determines how much light enters through the lens, achieving deep ...

    A digital camera file system standard; JEITA number CP-3461. [10] DIN: Deutsches Institut für Normung. A logarithmic system for expressing film speed in common use in Europe since 1934. Now combined with the ASA linear system, in the form of the ISO system. [4] DOF or DoF: Depth of field.

  7. Aperture priority - Wikipedia

    en.wikipedia.org/wiki/Aperture_priority

    To obtain this large depth of field, a narrow aperture (identified by a high f-number, e.g. f/16 or f/22) is necessary. Aperture priority mode also finds use in portrait photography , where a wide aperture (identified by a low number, e.g. f/1.4 or f/2.8) and therefore smaller depth of field may be desired to throw the background out of focus ...

  9. Bracketing - Wikipedia

    en.wikipedia.org/wiki/Bracketing

    DOF (Depth-of-field) bracketing comprises taking a series of pictures in stepped apertures , while maintaining the exposure, either by counter-shifting the shutter speed or, with digital cameras, adapting the ISO speed accordingly. In the first case, it will also change the amount of motion blur in the picture.
