Do you know the function of the three elements of photography? Do you know much about photography as a photographer? I have carefully combed the functions of the three elements of photography for everyone. What is the relevant knowledge and information? Come and study together.

What are the functions of the three elements of photography? 1 1, exposure.

By focusing and adjusting the shutter speed, the appropriate exposure can be controlled. Most digital cameras can control exposure by auto-focusing and adjusting shutter speed. This is the function of automatic exposure photography (AE). Although it is called automatic exposure, it can't be adjusted to the most appropriate exposure every time. Sometimes the picture will be too dark (underexposed) and too bright (exposed transition). When this happens, the function of correction is exposure correction.

2. Focus

The human eye will automatically focus on what it wants to see, so that we can see everything clearly. The lens of the camera will focus more vividly on the object to be photographed. The focal length is adjusted through the lens, while the digital camera has the function of automatically adjusting the focal length. This is the automatic focusing (AF) function. Although you can focus automatically, it is up to the photographer to decide which point to focus on.

Step 3 write a composition

The human eye can watch up, down, left and right continuously. But photos can only be observed and recorded from a rectangular range. Through the viewfinder or LCD, a very small part is selected as the shot picture in a large range, which is called framing. Recently, cameras are gradually developing towards automatic exposure and autofocus. However, no matter how the technology develops, it is impossible to fully automate the framing. So composition is the most important factor.

1, you should try to stay away from those colorful scenery (such as newly painted building exterior walls, large awnings, etc.). ), otherwise the colors of those scenes will be mapped to the characters, causing color cast.

2. Be careful not to take photos of people standing on the concrete floor at the top of the lamp, because the surface of the concrete floor is flat and the color of the face is light. This kind of bottom-up "footlights" will often have horrible effects and should be avoided as much as possible.

Be careful not to stand by the trees and take pictures. Light and shadow complement each other. The stronger the light, the deeper the shadow.

4. Be careful not to use high-speed film. In sunny sunshine, the light intensity is already very high. If you use high-speed film again, it will often force the aperture to be extremely small, or you can't use a slower shutter speed.

Second, photography skills:

1. When shooting, the camera must be mounted on a tripod to prevent the camera from shaking. Try to keep the camera close to the subject, and be careful not to introduce unnecessary shadows.

2. The focal track can make the camera move along the X-axis and Y-axis in very small increments, and can accurately control the camera position and the depth of field of the picture. It is very troublesome to move the triangular bracket to the ideal position.

3. The cable release device is installed on the tripod. If you are not careful when pressing the shutter, the camera may still shake, so in order to avoid this situation, I suggest you use cable release.

4. When shooting, when the background of the object is black, then the shot image can look the clearest.

5. Use a white card or wrap it with aluminum foil to reflect the light to the object to illuminate the shadow on the object. Be careful not to let this card appear in the shooting range.
