How to judge whether the photo exposure is normal? How to avoid it

The basic requirement of photography is to make sure that the exposure is accurate and the exposure is normal, but this is not a simple thing for many new photographers. There are often “over exposure” or “under exposure” in the shooting. What is the reason? What methods should we use to avoid this kind of situation? < / P > < p > accurate exposure is the basic skill of photography. There are three states of photo exposure: accurate exposure, under exposure and over exposure. < / P > < p > there are many ways to judge whether it is overexposed or underexposed. Here, I will introduce you to one of the most reliable judgment methods, which is to check the histogram to judge. < / P > < p > when we take a picture, select playback photo, and then press the button on the camera to call up the exposure histogram for viewing. < / P > < p > if the pixels on the histogram are concentrated on the left or close to the left, it means that the photo is dark, that is, under exposure or under exposure. < / P > < p > if the pixels on the histogram are concentrated on the right side or close to the right side, it means that the photo is bright and dark, that is, overexposure and overexposure. < / P > < p > in the M manual exposure mode, we can adjust the aperture size, shutter speed, and ISO to make the exposure normal. After adjusting the three elements of exposure, we can check whether the screen exposure is normal. We can also use the real-time display of the picture to shoot to determine whether the image exposure is normal or not. < / P > < p > in aperture priority mode, shutter priority mode and program automatic mode, you only need to adjust [exposure compensation] when the image exposure is incorrect. The exposure compensation increases when the image is dark and decreases when the image is bright. In real-time display shooting, the exposure compensation can also be adjusted to correct the exposure of the picture. < / P > < p > if we have finished the scene shooting and can’t take the unsatisfactory photos again, we can use the computer later stage to help us. We can process the raw format photos through software such as PS, and adjust the exposure value, highlight, shadow, contrast and other values to reach a reasonable value, so as to make the screen exposure more reasonable.
