    Other manufacturers may provide this functionality through an automatic selection of ISO speed in manual mode. 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 ...

  3. 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 ...

    The f-number N is given by: = where f is the focal length, and D is the diameter of the entrance pupil (effective aperture).It is customary to write f-numbers preceded by "f /", which forms a mathematical expression of the entrance pupil's diameter in terms of f and N. [1]

    Sv: Sensitivity value allows the photographer to control the ISO sensitivity, while aperture and shutter speed are calculated by the camera (this is a Pentax DSLR feature) M: Manual mode allows the photographer to control shutter speed, aperture and ISO independently. U: User mode (like program with preset)

  6. Aperture priority - Wikipedia

    en.wikipedia.org/wiki/Aperture_priority

    A Nikon-style mode dial showing aperture priority mode.. Aperture priority, often abbreviated A or Av (for aperture value) on a camera mode dial, is a mode on some cameras that allows the user to set a specific aperture value while the camera selects a shutter speed to match it that will result in proper exposure based on the lighting conditions as measured by the camera's light meter.

  7. Exposure value - Wikipedia

    en.wikipedia.org/wiki/Exposure_value

    The f-number (relative aperture) determines the depth of field, and the shutter speed (exposure time) determines the amount of motion blur, as illustrated by the two images at the right (and at long exposure times, as a second-order effect, the light-sensitive medium may exhibit reciprocity failure, which is a change of light sensitivity ...

  9. Deep focus - Wikipedia

    en.wikipedia.org/wiki/Deep_focus

    The actual size of the aperture will depend on the focal length of the lens. Deep focus is a photographic and cinematographic technique using a large depth of field. 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 ...
