Photography shutter aperture value of the relationship between ISO and use of.

On the photography skills, master the most basic is the basic operation of cameras, which are many beginners often do not understand photography friends. .Here I will simply introduce some basic knowledge of the camera bar. .ISO value: in the traditional camera and digital cameras which have this setting, it is the ability to film or CCD light-sensitive large about photography skills, master the most basic is the basic operation of cameras, which are often not a lot of novice photographers friends .too understand. .Here I will simply introduce some basic knowledge of the camera bar. .<p> ISO value: </ p> <p> in traditional cameras and digital cameras which have this setting, it is a photographic film or CCD capacity size. .The average household value of the film is 100 ISO general, this seems a standard value, as in the value of the following, we basically can achieve the correct exposure on various occasions, it is recommended beginner's friends can use this value to the operation. .If less than 100, such as 50 or lower, then the picture quality will be improved, the picture is more delicate, suitable for shooting portraits or still life scenes such as landscapes, the level is very rich. .Low-sensitivity image is brought into the light-sensitive according to longer hours, have to use to enlarge the aperture or slow down the shutter to complement the exposure required to achieve the correct picture. .If the speed is higher than 100, such as 200,400 or higher, then the film will enhance the grainy screen, CCD images have noise generated, and its benefits is that you can choose a faster shutter speed or smaller aperture, so that .by reducing the amount of light to achieve the correct exposure. .This approach is more suitable to capture a scene or dynamic scene movement, you can generate more rational use of special effects. .Here in a dark environment, increase sensitivity value is also a good way. .</ P> <p> Aperture: </ p> <p> the amount of light through the lens aperture control of a role, usually the larger the lens aperture (F value is smaller), the more the light through the large aperture brings .feature is the ability to get very shallow depth of field, is that the main clear, foreground and background blur effect, this means is often used in portrait photographs, to highlight the subject. .Of course, the focus of a large aperture must maintain the following accurate, otherwise the relatively shallow depth of field can easily become the focus according to the deviation. .The smaller the aperture (F value greater), the less the light through the small aperture can be obtained following a long depth of field, so more suitable for the performance of a broad landscape or environment, the range of sharpness greatly. .</ P> <p> Shutter: </ p> <p> changes with the aperture, shutter speed can be adjusted to achieve the correct exposure, the shutter is the length of exposure time, such as your aperture identified as F8, then the faster the shutter ., the less light coming in, the slower the shutter into the light for more rapid movement of shutter can instantly condense on the film or CCD, such as the gushing waterfalls, sparkling in the sun condensed into water droplets. .If the slow shutter speed, then the subject does not move is clear, the background of the people will become blurred motion effects, a vivid picture of strengthening. .</ P> <p> the relationship between aperture and shutter: </ p> <p> a scene when the correct exposure is determined, you can change the exposure in different combinations to achieve different effects, such as: a scene following the ISO100 .correct exposure value is the F8, 1 / 125, then you can choose to F5.6, 1/250---F11, 1 / 60, and so are many combinations of ways to control the performance of the screen, and there is a commonly used photographic .law "reciprocal rate" - is to ensure that the correct exposure, you can enlarge the aperture of a block, while increasing the shutter of a block, or reduce the aperture of a block, while slowing down the shutter of a block. .This is a shift in the relationship, zoom in or out a few f-stop, will the corresponding shutter speed up or slow down some. .In order to maintain the correct total exposure to ensure the picture quality, and constantly changing picture effect is through a combination of aperture and shutter to achieve. .Of course, such a failure rate of reciprocal time, such as shooting stars moonlight, and so a special environment here is not a simple reciprocal rate can be resolved, rely more on the photographer's experience and skill, this requires practice .summary. .</ P> <p> ISO value of the use of: </ p> <p> ISO value can control the exposure, generally increase the value of a block ISO, aperture narrow to get a block, or the shutter speed up access to a block, and vice versa .Ran. .This is also the need to effect the requirements of the screen to be adjusted. .In fact, photography is a combination of technology and art line of business, only under the premise of master technology in order to improve the ability of artistic expression, photography skills a lot. .</ P> <p> [Reserved] </ p> <p> </ p>.
