  2. Rotary disc shutter - Wikipedia

    en.wikipedia.org/wiki/Rotary_disc_shutter

    A tight shutter angle will constrict motion blur. A wide shutter angle will allow it. A 180° shutter angle is considered normal. So for instance, at 24 fps the frame interval value is 0.04167 second ( = 1 ⁄ 24). Using an exposure time of 1 ⁄ 50 second gives a shutter angle value of 173°, very close to 180° (normal motion blur effect).

  3. Focal-plane shutter - Wikipedia

    en.wikipedia.org/wiki/Focal-plane_shutter

    Focal-plane shutters may also produce image distortion of very fast-moving objects or when panned rapidly, as described in the Rolling shutter article. A large relative difference between a slow wipe speed and a narrow curtain slit results in distortion because one side of the frame is exposed at a noticeably later instant than the other and the object's interim movement is imaged.

  4. 35 mm equivalent focal length - Wikipedia

    en.wikipedia.org/wiki/35_mm_equivalent_focal_length

    35 mm equivalent focal lengths are calculated by multiplying the actual focal length of the lens by the crop factor of the sensor. Typical crop factors are 1.26× – 1.29× for Canon (1.35× for Sigma "H") APS-H format, 1.5× for Nikon APS-C ("DX") format (also used by Sony, Pentax, Fuji, Samsung and others), 1.6× for Canon APS-C format, 2× for Micro Four Thirds format, 2.7× for 1-inch ...

    Adjustment – how the shutter angle can be adjusted. Most manual designs can only be adjusted when the camera is not running, often with the lens removed. All electronic shutters allow adjustment at all times, including when the camera is running. Angles – shutter angles available and in what increments or stops, if not continuous.

  6. Arriflex 435 - Wikipedia

    en.wikipedia.org/wiki/Arriflex_435

    Arriflex 435ES. Arri debuted two models of the 435 in 1995: the 435 and 435ES. The latter is suffixed ES to denote electronic shutter capabilities; this means that the shutter angle is able to be continuously electronically adjusted, even while the camera is running, and set to any angle within a specific range (11.2° to 180°) to a great deal of precision (0.1°).

  7. 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 ...

  8. Angle of view (photography) - Wikipedia

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

    So a standard 50 mm lens for 35 mm photography acts like a 50 mm standard "film" lens even on a professional digital SLR, but would act closer to a 75 mm (1.5×50 mm Nikon) or 80 mm lens (1.6×50mm Canon) on many mid-market DSLRs, and the 40-degree angle of view of a standard 50 mm lens on a film camera is equivalent to a 28–35 mm lens on ...

    The crop factor for the panoramic format (based on diagonal angle of view) compared to "full-frame" 135 is 0.62; for example, the 90 mm XPan lens in panoramic mode would have the equivalent coverage across the diagonal of a lens with a focal length of approximately 55 mm on a standard 135 film camera.
