Shutter (Shutter) ------ elementary wisdom of phot

Shutter (Shutter) is to control the camera exposure period of the chapters; shutter period shorter, less exposure time.

shutter go process diagram:







in consensus with the shutter in the camera location is classified as: before the mirror shutter, lens shutter, hole, shutter, mirror shutter,GHD Hair, mirror shutter, focal plane shutter.

mirror shutter
original front of the camera's shutter is just a cover, the front of the camera by hand exposure lowered the lid, the lid by hand later exposure. Later promotions to air two leaf shutter. Mirror shutter for miniature cameras, such as Eddie more than 16 Sa, dense North.
Eddie Sa 16 front of the camera shutter is composed of 4 slender metal blade,GHD Precious Gift Set, the highest speed is 1 / 150 sec. Northrop B-
near the front of the camera miniature camera shutter by two thin metal blades, speed: T, B, 1 / 2, 1 / 5, 1 / 10, 1 / 20, 1 / 50, 1 / 100,1 / 250,1 / 500, 1 / 1000 sec.
mirror shutter advantages: simple building, effortless assembly
mirror shutter drawback: for ashore the front of the lens, so the shutter open to a large diameter, cover to lest light way, so hiking distance to the shutter blades longer, so the shutter speed is slower


many mid-range lens shutter 35mm camera, dual camera, middling format, and the simplicity of modern 35mm cameras, APS cameras with leaf shutters.
Bolingezi Factory Turners TENAX CommScope camera shutter early lens shutter consists of 2 small turntable control, such as Bailingezi (CPGOERZ) plant Turners (TENAX) camera with the CommScope lens shutter and a dial control: 1,1 / 2,1 / 5,1 / 10,1 / 25, 1 / 50,1 / 100,1 / 250; dissimilar control dial D (equivalent to T ) and Z (the equivalent of B).

more lens shutter blades manufactured from page iron, with 2,3,5-chip to 5 most general. Also known as lens shutter leaf shutter. Lens shutter advantages: easy and small, multi-camera in a easy to use. Flash can synchronize at shutter speeds of always.
lens shutter drawback is namely if you absence to alteration the lens:
every lens requires a shutter (such as the Hasselblad). Lens shutter, aperture, together with the camera even after half of the lens does no move on, only for the first half of the lens; such as Kodak, whether Timna (RETINA) 35 毫米 SLR cameras and Zeiss Ikon's Contador reflective machines take over B this design.

camera aperture shutter aperture
some simple function of either the shutter, aperture shutter most of these double-blade diamond hole. Aperture shutter is routinely entirely closed: the instant the shutter is pressed, double-blade iris shutter open to a predetermined aperture, the aperture to maintain the shutter open for a predetermined time immediately after the closure: this path, the aperture and shutter right afresh functions, many of lightweight cameras use aperture shutter.

mirror shutter
the Great Wall-size SLR cameras DF4 (DF120) mirrors, twice shutter. Posted before the metal version of the twice mirror of the premier shutter shutter, the second curtain is bent metal curtain. Winding up the curtain while the mirror pushes, left axis, yet the arbitrage of the second curtain too moves up, stop the light. Press the shutter button, the first arc of the second curtain down, wait forward with mirror curtain down, the formation of a breach among two curtains. The gap is small shutter speed is tall, a large gap lower shutter speed. World War II German instrument Hager plant Aike Sa 35 mm SLR camera with a similar shutter.

focal plane shutter curtain
called focal plane shutter Shutter. Early focal plane shutter is a long black fabric paste,GHD Midnight Gift Set 2011, the altitude row of a few rectangular holes, a more than a narrow. When a rectangular hole to move even faster than light-sensitive film, the exposure of the film will be. The more lessen hole, less light on the film, the higher the shutter speed equivalent. The next tread of evolution is to form a curtain with two hole breadth can change. Curtain of black cloth and metal coating materials; metal focal plane shutter curtain, multi-piece strip of sheet metal by the composition of the contiguous metal slices slightly overlapping, do not leak light. The operation of the shutter curtain open instruction,GHD IV Black Straighteners, horizontal and vertical two. Today a crowd of the shutter curtain is made of thin aluminum sheet, some are manufactured by a titanium alloy.

constructed according to the classification of the shutter: mechanical shutter, electromagnetic shutter

mechanical shutter
the original definition: only the spring alternatively other mechanical structure, without relying on electricity to drive the shutter structure
current definition: tin be nailed by the mechanical components to steer the shutter structure-driven reach for the spring, solenoid valves and other components ....

electromagnetic shutter
double electromagnetic shutter.
full electromagnetic shutter control mechanism fashioned by the electromagnet (the manufacture term is called the electromagnetic valve), controlled by the electronic circumference when the body makeup. Today's electronic circuits electromagnetic shutter in both quartz-piece timing components, electromagnetic shutter exactly than the mechanical shutter.

B shutter
When the shutter button is pressed, the shutter is open, until you release the shutter button before the shutter closes, the shutter is cried B shutter.
