In order to get the correct exposure, you need the correct shutter and aperture combinations. When the shutter is fast, the aperture is necessary; shutter slow, aperture will be smaller. Shutter priority metering system automatically by the Lenovo 3000 N500 Battery machine to calculate the exposure amount of value, then decide how much aperture you selected shutter speed automatically. Aperture priority metering system automatically by the machine to calculate the exposure amount of value, then decided to use the number of shutter automatically according to the size of the aperture you selected. Shooting, the user should be combined with the actual environment to adjust the balance so that both the exposure and the shutter, complement each other.The larger the aperture the more light per unit time through, and vice versa. General representation of the aperture for the letter "F value", such as F5.6, F4 and so on. It should be noted that smaller values, indicating that the larger the APPLE A1185 Battery aperture, such as F4 than, F5.6 aperture, and two adjacent aperture value between the difference of twice, that is adopted by the F4 than F5.6 light to be twice as large. The definition of the shutter is relatively very simple, is to allow the light through the aperture time, the manner indicated in number, for example, 1/30 second, 1/60 seconds, the same two adjacent shutter between the difference of twice the .The combination of aperture and TOSHIBA PA3479U-1BRS Battery shutter exposure, in certain circumstances of the exposure, this combination is not the only one. For example, measure the normal combination of exposure F5.6, 1/30 seconds, if the aperture is increased level is the F4 shutter value to 1/60, this combination also can reach exposure. Different combinations can achieve the same exposure, but taken out of the picture is not the same effect.Shutter priority camera metering for shutter manually define the aperture value. For example, shutter priority used for shooting moving objects, in particular, is the most commonly used in sport shooting. Many of my friends found when shooting moving objects, often taken out of the SONY NP-F960 battery subject is vague, it probably is because the shutter speed is not fast enough. In this case, you can use the shutter priority mode, probably determine the value of a shutter, and then shoot. Shutter faster, and may reduce the amount of light, subdued colors, which need to increase exposure to enhance the image brightness. The object of the operation are generally regular, then the value of the shutter can be roughly estimated, for example, shooting pedestrians, shutter speed 1/125 sec about the whereabouts of the drop shot is 1/1000 seconds.Photography, good focus, the ACER Aspire 5738G Battery scene in order to form a clear image. However, in some cases, for example, shooting at different distances on a variety of scenery, on-chip samples to select the focusing target, focus on where, what can all the scenes shot clearly, is a weighed his. Moving body photography, the location of the subject is moving, the adjustment is particularly difficult. Encounter this situation, how can we lose no time and have a grasp a clear picture? These are the need to apply depth of field theories and methods to solve practical problems. Photography camera front of your subject focus, located in the main, after the scene in the Lenovo 3000 Y410 Battery film image is not as good as the main clear. However, due to the limited ability to identify the human eye, we always think your subject before, after some distance, the image of the scene look is also clear. The scope of this recorded clearer subject before and after the focal point of the scene depth, called depth of field. In other words, the depth of field (distance), the objects in the distance should be clear. Focus where the depth of field to follow where the objects in the depth of field (the distance) on a clear, beyond the Compaq Presario A900 battery depth of field (the distance) is fuzzy object. The greater depth of field, depth clear of the scene the greater the smaller; depth of field depth clear of the smaller.
