How to use and connect the three elements of exposure in a camera?

Three elements of exposure: shutter, aperture and sensitivity; \x0d\ 1, shoot high-speed moving objects with a high shutter speed of11000, and shoot with a small aperture to improve iso and increase picture brightness; \x0d\ 2。 When shooting a moving object, if we want to show the motion of the subject, then we can slow down the shutter speed appropriately and deliberately make the picture a little mushy, so that it looks more dynamic; Long exposure requires ND filter; \x0d\3。 When the light is dim, we need to use a slow shutter to increase the exposure. For example, shooting at night, we often use the shutter speed of a few seconds, sometimes it takes more than 10 seconds, and it is necessary to improve the iso if necessary; \ x0d \ x0d \ aperture is a device that controls the amount of light entering the photosensitive surface of the fuselage through the lens. The larger the aperture, the more light can pass, and vice versa. \x0d\\x0d\ usually has the following usage for aperture: \x0d\ 1. Aperture can control the length of depth of field. Under the same parameters, the depth of field of a large aperture is large, so when we need to blur the background, we usually use a large aperture. On the contrary, if you want to get a greater depth of field, you should use a smaller aperture as much as possible. \x0d\2。 We usually use a small aperture when shooting silhouette effects. \ x0d \ x0d \ sensitivity (ISO), as the name implies, reflects the sensitivity of camera sensors to light, and the general range is 100 ~ 6400 (many cameras can extend it to 12800), with iso 100 being the lowest (there are also 64) and iso6400. \x0d\\x0d\ Low iso can control noise well and get good image quality. On the contrary, there are many high iso cameras with poor image quality, especially above iso800, which is almost unacceptable (some cameras are not suitable, such as Sony A7S). Iso has a great influence on exposure. Low iso requires a larger exposure, while high iso requires a smaller exposure. \x0d\\x0d\ A properly exposed photo is a combination of the three. In many cases, you can shoot with aperture priority AV file and shutter priority TV file; On this basis, good composition can make your photos become good photos;
