Photography's root comes from the Greek roots "photo" which means light, and "graph" which means to write or scribe. Photography is all about light and how to interact with it. Two basic functions of an SLR camera accomplish this through the aperture and shutter speed.


Shutter speed refers to the amount of time that the film Cheap Mens Jerseys , or in the case of a digital SLR, how long the image sensor is exposed to light. Depending on the camera, shutter speeds can vary from 30 seconds to 18000 of a second. Some cameras have a 'bulb' mode that allows the user to open and close the shutter manually using a switch.


The aperture setting of a camera refers to the amount of light that is let into the camera body by the lens. An iris contracts or expands depending on this setting on the camera, thus controlling the light that hits the film. Aperture terminology may be confusing as the "higher" the aperture, the lower its number. Lenses are rated by their aperture and focal length. For instance Cheap Jerseys Online , Canon might have an F2.8 28-75mm lens. The F prefix is the highest aperture that the lens can produce. In this case, an aperture of 2.8 is the maximum amount of light that the lens can let in. A lens that has a high aperture is considered a "fast" lens.


Shutter speed and aperture values are at a constant tug-of-war concerning light. Suppose someone was a handed a camera and was told that its aperture and shutter settings were set to ensure proper exposure using a shutter speed of 160th and an aperture of F8. However, suppose that they wanted a faster shutter speed to capture a moving object, so they set the shutter speed to 1250 and took a picture, they would get an underexposed photo because they didn't allow the film to be exposed for the 160th of a second it needed. Therefore Cheap Jerseys Wholesale , they would need to change the aperture to allow more light in, perhaps by changing it to F1.8, or whatever the maximum aperture of the lens is. It is always good once you have changed your settings to check them with a light meter and see if you are giving enough light for proper exposures.


More on Shutters


Cameras traditionally have two shutters, or curtains, that cover the film ready to be exposed -- one shutter sits over the film and one rests off to the side. Once the shutter button has been pressed Cheap Jerseys From China , the first curtain is moved away so that the film is exposed to the light coming through the lens. Once the film has been exposed for the length of the set shutter speed, the second curtain moves into the position that the first curtain initially sat. Why can't there be just one shutter? For two reasons.


First, if the shutter speed is set to 11000 of a second, the shutter would have to move away from the film over a short period of time. Once the shutter has completely moved away from the film, the edge of the film that was last uncovered by the shutter has been exposed less than the edge of film that was first uncovered. This means that if a single shutter were to come back the way it left across the piece of film Cheap Jerseys China , it would again underexpose the already underexposed edge of the film, leaving the m.
