SLR camera tutorial

1 Aperture priority is mostly used for portraits or landscapes. Aperture priority is to manually define the aperture size, and the camera will determine the shutter speed based on this aperture value. Since the size of the aperture directly affects the depth of field, this mode is most widely used in ordinary shooting. When shooting portraits, the long focal length of the large aperture is generally used to achieve a shallow depth of field effect due to the blurred background, which can highlight the subject. At the same time, a larger aperture can also obtain a faster shutter value, thereby improving the stability of hand-held shooting. When shooting landscapes, smaller apertures are often used, so that the depth of field is relatively wide. This makes it possible to make distant scenes and nearby scenes clear. This also applies when shooting night scenes.

2 Shutter priority is mostly used for shooting moving objects. Shutter priority is to obtain the aperture value by camera metering with a manually defined shutter. A lot of friends found that when shooting a moving object, the subjects that are often shot are blurred, which is mostly because the shutter speed is not fast enough. In this case, you can use the shutter priority mode, determine a shutter value, and then shoot. And the object's operation is generally regular, then you can roughly estimate the value of the shutter, such as shooting a pedestrian, the shutter speed of about 1/125 seconds, while shooting drops of water drops need 1/1000 seconds.

3 portrait shots. First of all, telephoto is used. A telephoto of 3 to 4 times is very suitable for portraits. The wide-angle end makes the figure somewhat distorted. Over 4 times or even longer focus will make the face too flat. Second, the aperture priority, choose a large aperture, large aperture can make the shutter faster, reduce the shaking, and make the background as much as possible blur. It is best to select spot metering, spot metering on face, and use exposure lock. Because other metering methods are easily affected by the color of clothes, face exposure is not normal. At the end of the composition, the best figure is 1/3-1/2, and the face is at the top 1/3. The portrait shots that are made like this will be lively, with visual impact, and will look better.

4 how to take a good macro. First, use a tripod. Hand-held instability, always see the paste after magnification, so the first, with a tripod. Second, use a self-timer. We found that even when using the shelf, the shaking is still brought in when the shutter is pressed, the best way to start the self-timer

5 Use of exposure compensation. Press the +, - keys, there will be exposure compensation adjustment bar, left and right keys to adjust the positive and negative compensation and size, once 1/3 level. After adjusting, press +- button to confirm.

6 Use the grid lines on the screen to compose pictures. The golden ratio gives a sense of beauty. Therefore, arranging interest points in the film on four focal points, or on the dividing line, will give people a visual sense of beauty. The grid line provides us with such a reference.

7 Before the sun sets or cloudy. Day or night, we can get the effect we want, automatic white balance is very accurate. However, during the period before and after the sun set, or in cloudy weather, the film shot was very unsatisfactory. In this case, it is necessary to adjust the white balance, first pull the manual file to the start of P file, press the function key, select to cloudy days, press the function key to confirm. If it is still not ideal, set manual white balance.
