How to determine the exposure when taking pictures in natural light?

Determining exposure is an important part of the shooting process. Only when the photographic film is sensitive accurately and the darkroom is made well can a good photo be taken. Let's talk about taking pictures in natural light and some problems related to exposure.

First, the light source. Throughout the year, the position of the sun is different. There are morning, noon and evening in a day, and there are differences between sunny days and rainy days, which determine the difference of sunshine every hour. This difference is sometimes large and sometimes not obvious. According to the experimental data, the degree of sunny and cloudy weather is summarized as the exposure required for taking pictures under several different weather conditions for people's reference. This exposure manual is printed on the packaging cover of the film or packed in a box. The data in the manual is the basis of shooting exposure, so make good use of it. When we have a basic basis for exposure under different lighting conditions through the manual, we should also study the brightness of the scene to make the determination of exposure more accurate. Let's say it at three o'clock.

1, different scenery, its own color is deep and shallow, deep and dark, shallow and bright.

2. The light receiving direction of the scene can be divided into sunlight and backlight, and sunlight and backlight.

3. The reflected light from the surrounding environment will also affect the brightness of the scene, which is easily overlooked by ordinary beginners, but it is an extremely important issue.

The above three aspects determine the brightness of the scene, and the exposure can be increased or decreased according to its brightness when shooting.

It should also be pointed out that:

1. The exposure of a scene dominated by people depends on the brightness of people's faces.

2. When shooting in special weather, there is no exposure meter, and the exposure cannot be set accurately, and the shooting content is very important, and the shooting opportunity is rare, three different exposure data and three photos of continuous shooting can be used. That is, take one with your own exposure, and then take one with the data of each level of addition and subtraction, so as to select the best negative.

The above points are all about the basic points. Photographers can also change all the details between you and the final image in practice after exposure and tone adjustment, and learn from other people's experience and apply it to their own shooting practice.
