What is the best way to deal with camera exposure?

Exposure is a commonly used term in photography, which is the amount of natural light that enters the camera when shooting. If the amount of light is too large, the photos will appear very bright, which is called overexposure; If there is too little light, the photo will appear very dark, which is called underexposure. Grasping the intensity of exposure plays a very important role in the quality of a photo. The exposure mode is: 1. Automatic exposure Automatic exposure is an exposure mode in which a digital camera automatically analyzes and selects the exposure intensity according to the light condition, which is also known as fool operation. This method has no technical content, and everything depends on the automatic identification of digital cameras. Automatically set the aperture and shutter speed according to the specific situation of shooting scene light. When the light is insufficient, the camera will automatically turn on the internal flash. In some news reports and emergencies, in order to seize the time, automatic exposure is generally used. 2. Shutter priority Shutter priority is to automatically obtain the aperture value through camera metering when the shutter speed is manually defined. When shooting moving objects, we often find that the subject is blurred, mostly because the shutter speed is not fast enough. In this case, you can use the shutter priority mode, roughly determine a shutter value, and then shoot. When the shutter speed is lower than 1/60 seconds, it is recommended to use a tripod to shoot, so as not to affect the photo clarity due to hand jitter. The faster the shutter, the less light enters; The slower the shutter, the greater the amount of light. Shutter priority is mostly used to shoot moving objects, especially sports shooting. High-speed shutter can be used to solidify the instantaneous state of the object, while slow shutter can realize the blurring of the moving object. 3. Aperture priority Aperture priority means that the photographer first chooses the aperture needed for shooting, and then the camera determines the required shutter speed according to the lighting conditions on the spot. The larger the aperture, the greater the amount of light entering, the more obvious the effect of background blur, and the more prominent the subject is; The smaller the aperture, the smaller the amount of light, and the greater the depth of field before and after focusing. Generally speaking, macro photography often uses a larger aperture to achieve the purpose and effect of blurring the messy background. In order to obtain clear and detailed images before and after landscape shooting, a smaller aperture is often used for shooting. Large aperture is suitable for macro shooting, and small aperture is suitable for landscape shooting. 4. Manual exposure mode Manual exposure mode The aperture and shutter speed required for shooting are completely determined by the user. Users can set the aperture and shutter speed according to their artistic creation intention and expected shooting effect, which provides users with great freedom. When the setting exceeds the sensitivity, the camera will prompt you by sound or flash. For inexperienced novices, manual exposure mode is difficult and the operation is slightly complicated, so it is difficult to capture fleeting scenes. 5. Exposure compensation adjustment Exposure compensation adjustment In the Gao Fancha environment with complex light and strong contrast, it is sometimes difficult to give consideration to the overall situation by using automatic exposure or shutter and aperture priority mode, and it is impossible to highlight the theme and achieve the expected effect. At this time, the photographer needs to manually adjust the exposure parameters corresponding to the equipment, that is, expose value, which is also commonly known as EV. For beginners, exposure compensation is generally used for still life and scene shooting. This situation is suitable for calmly adjusting parameters and taking photos of different compensation schemes for selection. However, in the contrast picture, it is difficult to give full consideration to exposure compensation, and it is easy to lose sight of one thing and lose sight of another. Generally, exposure compensation is used in automatic or semi-automatic exposure mode. If it is a full manual exposure mode, exposure compensation is rarely used, because the amount of light entering can be changed by adjusting the shutter and aperture.
