Basic theory course of photography

The first one should say that you have observed it carefully, and it is true.

Second, if the exposure is perfect, there is basically no need to adjust it later. Know why you want to tune it before you tune it. Do you think the overall color is not eye-catching or too dark, or do you think the theme is not prominent? You should lighten or darken the theme to contrast with the whole picture. The idea of being close to the real scene doesn't mean that every photo is adjusted as you say. There are many realities. For example, on cloudy days, the general environment is gray and the contrast is not very large. Therefore, increasing exposure compensation can basically restore the truth. On a sunny day, the light is very good, and it doesn't take much effort to take a well-exposed photo. More experience should come from practice, and try it directly on the camera through methods such as bracketing exposure. After all, this is a practical activity.

Third, it depends on what your real scene is. After all, the lens is not human eyes, so it is very difficult to judge the correct exposure when using black and white objects. At this time, it is necessary to fill the light by hand to get more accurate exposure. Now that technology is so advanced, you can get a perfect exposure by taking one shot and then another and controlling the direction of light.

Anyway, it's still one. Practice is the best way. Reading is just a supplement to practice. 18% should be taken by you, not seen by you. Good luck!
