(Redirected from Shutter angle)
When the shutter is open, the film is exposed. When it closes, the next frame of film is brought into position by the claw.
Adjusting the shutter angle affects the amount of time that film is exposed to light.
A rotary disc shutter is a type of shutter. It is notably used in motion picture cameras.
Rotary disc are semicircular mirrors which rotate in front of the film gate, and thus expose the film. As the mirror spins it reflects the image into the ground glass so that it can be viewed by the camera operator part of the time. The other part of the time the mirror allows the light to pass on to the film. On simple cameras this shutter is fixed and usually semi-circular. On more advanced cameras the shape of the shutter can be adjusted. This shutter setting is referred to as the shutter angle.
Adjusting the shutter angle controls the proportion of time that the film is exposed to light during each frame interval. The angle of the shutter forms a proportion to the time that each frame of film is exposed:
The primary reason that cinematographers adjust the shutter angle is to control the amount of motion blur that is recorded on each successive frame of film. A tight shutter angle will constrict motion blur. A wide shutter angle will allow it. A 180 shutter angle is considered normal.
Tight shutters create a stuttering stop motion animation look that has become popular in action and war films. In particular tight shutters are used to capture particles flying through the air, such as dirt from an exploding mortar.
On most film cameras the shutter angle is changed by removing the lens and adjusting the shutter with a special tool. This cannot be done while the camera is operating. Some cameras such as the Arriflex 435ES can modify their shutter angle during the shot. This is sometimes referred to as an electronic shutter. An electronic shutter can compensate for the exposure change caused by a speed ramp without changing the aperture and affecting depth of field.
Other types of shutter adjustment such as an out-of-phase shutter, and a fluttering shutter are also possible. Normally the film is held steady in the gate whenever it is exposed to light. Special shutter adjustments allow the film to be exposed while the camera mechanism is actually moving the film to the next frame. In the film Saving Private Ryan, cinematographer Janusz Kaminski used such a shutter adjustment to give his film the look of World War II newsreel photography. Previously, this effect could only be achieved by purposefully mis-adjusting the timing belt of the film advance mechanism in the camera. However, several manufacturers now provide accessories to electronically control the phase relationship of the shutter and film advance mechanisms. One such device is the Timing Shift Box available for the above mentioned ARRI 435 series.
Electronic equivalent
Many video cameras also provide the ability to adjust their shutter. In most cases the camera does not have an actual mechanical shutter. Instead, this adjustment controls the amount of time that the electronic sensor collects light in order to create each successive image. Because electronic cameras do not need to mechanically advance film, it is possible for the shutter to be open for nearly the entire period of each successive frame. At 24 frames per second, it is possible to expose a frame for nearly 1/24th second, achieving longer motion blur otherwise impossible to achieve on film at sync sound speeds.
The term electronic shutter is often used to describe the electronic process of controlling exposure time on a light sensor. The same term is also used in film cameras to refer to a mechanical rotary shutter which can adjust its shutter angle electronically while shooting.
Rotary shutters on still cameras
While the vast majority of rotary shutters are naturally used on motion-picture cameras (as well as projectors), there were some still cameras that employed this type of shutter, notably the Univex Mercury and the Olympus Pen F SLR. Both of these cameras were half-frame 35mm cameras (frame size 18 x 24 mm). The rotary shutter proved to be very simple to construct, accurate and reliable in these cameras, though in the case of the Univex it resulted in a very strange "hump" on top of the camera to cover the shutter disk.
