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).
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.
Cross-section of a typical retrofocus wide-angle lens. Extreme or ultra-wide-angle lens - a wide-angle lens with an angle of view above 90 degrees. [4] Extreme-wide-angle lenses share the same issues as ordinary wide-angle lenses but the focal length of such lenses may be so short that there is insufficient physical space in front of the film ...
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 ...
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 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 ...
The alternative to a central or behind-the-lens shutter is a focal-plane shutter. Interchangeable-lens cameras with a central shutter within the lens body require that each lens has a shutter built into it. In practice most cameras with interchangeable lenses use a single focal plane shutter in the camera body for all lenses, while cameras with ...
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°).
