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).
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 ...
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°).
A drop shutter-like mechanism with an adjustable slit was used at the focal plane of an apparently one-off William England camera in 1861 and this is considered the first FP shutter of any kind. [35] If the lens on a single curtain FP shutter camera has its lens cap off when the shutter is cocked, the film will be double exposed when the blind ...
Each exposure required the photographer to change the film holder, open the lens shutter, cock the focal plane shutter, remove the dark slide from the inserted film holder, focus the camera, [a] and release the focal plane shutter. Conversely, if the lens shutter were used, the focal plane shutter (on the Speed Graphic and Pacemaker Graphic ...
The Olympus Pen F, Pen FT and Pen FV are very similar half-frame 35 mm single-lens reflex (SLR) cameras with interchangeable lenses produced by Olympus of Japan between 1963-1966 (Pen F), 1966-1972 (Pen FT) and 1967-1970 (Pen FV). The original Pen F has a double-stroke film advance and a distinctive logo rendered in a gothic font.
Reflex – is the shutter a reflex mirror design? Design – rotary disc shutters have two common designs – a "half-moon" disc of 180° or "butterfly" of two e.g. 90° segments opposite each other which spin at half-speed. Location – where the shutter is centered; Adjustment – how the shutter angle can be adjusted. Most manual designs can ...
The specified times apply to black/white film. Note that the times are approximate, and vary between different films and ASA numbers, but the table shows in general how the exposure time is adjusted. In photography , reciprocity is the inverse relationship between the intensity and duration of light that determines the reaction of light ...
