  2. Canon EF camera - Wikipedia

    en.wikipedia.org/wiki/Canon_EF_camera

    The camera included setting for film speeds of 12 ASA to 3200 ASA. The EF also featured a self-timer and a stop-down metering mode which could also be used for momentary depth-of-field preview. Stopped down metering must be used with older Canon FL lenses. The mirror can also be locked up for long exposures, to minimise shutter-induced camera ...

  3. Shutter speed - Wikipedia

    en.wikipedia.org/wiki/Shutter_speed

    The shutter speed dial of a Nikkormat EL Slow shutter speed combined with panning the camera can achieve a motion blur for moving objects. In photography , shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light (that is, when the camera 's shutter is open) when taking a ...

  4. Coded exposure photography - Wikipedia

    en.wikipedia.org/wiki/Coded_Exposure_Photography

    Digital Camera. Coded exposure photography, also known as a flutter shutter, is the name given to any mathematical algorithm that reduces the effects of motion blur in photography. The key element of the coded exposure process is the mathematical formula that affects the shutter frequency. This involves the calculation of the relationship ...

  5. Digital camera modes - Wikipedia

    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 ...

  6. Canon EF-M camera - Wikipedia

    en.wikipedia.org/wiki/Canon_EF-M_camera

    The Canon EF-M was a manual-focus 35mm film, SLR camera which used the Canon EF lens mount. It was introduced in 1991 for export to the non-Japanese market, and was the only manual focus camera in the EF line. It was not sold as part of the EOS range; the camera's official name was Canon EF-M rather than Canon EOS EF-M.

  7. Canon EOS 50D - Wikipedia

    en.wikipedia.org/wiki/Canon_EOS_50D

    The Canon EOS 50D received generally favourable reviews. Digital Photography Review concluded: "Looking at the specification differences between the EOS 40D and our test candidate it appears you pay quite a premium for the 50D's extra megapixels and as we've found out during this review you don't get an awful lot of extra image quality for your money.

  8. Shutter (photography) - Wikipedia

    en.wikipedia.org/wiki/Shutter_(photography)

    If a focal-plane shutter camera is left with sunlight falling on the lens (and the mirror up for an SLR), it is possible to burn a hole in the closed curtain of a non-metal shutter. Camera shake due to the impact of the larger curtains starting and stopping rapidly. Camera designers have learned to overcome SLR mirror-slap by including a mirror ...

  9. Shutter lag - Wikipedia

    en.wikipedia.org/wiki/Shutter_lag

    Shutter lag is much more of a problem with digital cameras.Here, the delay results from the charging of the charge-coupled device (CCD) image sensor and relatively slow transmission of its capture data to the circuitry of the camera for processing and storage.
