Summarize photography skills in a few sentences.

The smaller the aperture, the greater the depth of field, and the clearer the foreground background including the subject;

The larger the aperture, the smaller the depth of field, and the more blurred the foreground background except the subject.

(Note that the size of the aperture is inversely proportional to the numerical value. For example, F2.8 is a large aperture, while F8 is a small aperture. The meaning of depth of field: after the subject is clearly focused, keep a clear range before and after. )

The higher the shutter, the more you can capture the moving subject, and the more light you need, which is often used when freezing action movies; The lower the shutter, the more illusory effects can be created, such as waterfalls. At this time, it is very important to have a stable tripod, which is often used when shooting landscape films.

The advantage of high sensitivity value is that the shutter speed can be increased in weak light, but at the expense of image quality, it is a last resort when the main purpose is to record scenes. The higher the sensitivity, the higher the noise;

The advantage of low sensitivity is that the lower the sensitivity, the finer the picture quality and the more oily the color.
