What are the photography techniques?

At that time, the light at the scene was very flat, and the color and light of cactus in the scenic spot were relatively average. Using the central focus average metering mode, you can get photos with correct exposure. In order to get the correct exposure, we need to use different photometry methods in different situations. At the same time, mastering photometry can let us give full play to the creativity of light and shadow and shoot extraordinary works in ordinary scenes. First of all, let's learn about the camera metering mode. With the improvement of camera automation, there are more and more camera metering modes, but the most commonly used and practical ones are the following three: 1, multi-area metering, also called evaluation metering. The method of multi-area photometry is that the camera divides the picture into several areas, and then arranges them independently to get a complete exposure value. Multi-area photometry often gives priority to the main target to be focused, because in most cases, the main target of focusing is the part that needs to be exposed correctly. Multi-area photometry can easily obtain accurate exposure results even for people who know nothing about photography. Therefore, multi-area metering is the most advanced and popular metering method at present, and it is also the default metering method for high-end automatic cameras at present. 2. Center key average metering. This is the metering mode commonly used by most cameras, and it is also the most widely used. Central focus photometry means that the exposure reading is most affected by the central area and least affected by the four corners of the picture. Usually, central focus photometry is sensitive to the central 2/3 part of the picture (the specific range varies according to different brands of cameras), and some cameras pay attention to the bottom (level) of the picture to reduce the influence of the sky on the scenery. Under normal shooting conditions, center-focused photometry is a very practical photometry mode, but if the main body of the picture is not in the center or shot in reverse light, it may cause photometry errors. 3. Spot metering: also known as key metering, it is metering in the area of 1%-5% within the framing range. Spot metering mode is rarely used and is not easy to master. But in some cases, spot metering can play an important role. Knowing when spot metering should be used and using spot metering correctly can make the exposure of the subject accurate on the one hand, and create wonderful pictures that can't be seen in reality by using "sensitivity tolerance" on the other hand. Use spot metering: The following is an example of how to use the spot metering mode. Application of spot metering mode: spot metering mode is suitable for the case of uneven light distribution and large contrast in the view frame. In this case, if spot metering is not used, the exposure of the subject to be represented may be inaccurate, too bright, resulting in a white picture without layers, or too dark to see the details clearly. Exposure locking: Before using spot metering mode, you need to know the knowledge of exposure locking. The metering point of the camera fixed-point metering is in the center of the scenic spot. When using spot metering, it is necessary to aim the center point of the scenic spot (the metering point of spot metering) at the subject to be represented to measure the light. If the subject you want to show is not at the center point, you can aim at the subject with spot metering first, and lock the data measured by the subject with the camera's exposure locking function. Finally, according to your own ideas, re-compose, focus and press the shutter. Yd '`` ~ h) At+b Most cameras have a special exposure lock button, which allows us to use the exposure lock easily and reconsider the composition. However, there are also some cameras whose exposure locking and focusing are achieved by half-pressing the shutter. If the metering point is inconsistent with the focus point, it is necessary to meter a certain point first, then lock the exposure, and then re-compose and focus. Some cameras cannot provide separate exposure lock and focus lock. You can also record the exposure data after turning on the subject, then set the camera shooting mode to M file, set the exposure data according to the turned-on data, and then focus on the composition. Understand and master the above basic knowledge, and then through practical attempts and experience accumulation, I believe that friends who are beginners in photography will be able to take satisfactory and surprising photos. From the perspective of framing environment, the main body to be represented is bright lotus, while the lotus leaf is dark, and the uneven stems affect the composition. When shooting this film, lotus leaves reflect more light, while lotus leaves and ponds reflect less light. By using the spot metering function of the camera, the petals of the main lotus can be exposed correctly, highlighting the good colors and details of the lotus, while the pond is underexposed, and the dark part covers the layers of stems, which highlights the main lotus better. People should also pay attention to metering. The most important thing in portrait photography is to show people's faces. In this picture, natural light is used to shoot the face, so that the face is exposed correctly, and the surrounding environment and clothes are darkened due to insufficient exposure. The picture is simple and the characters are prominent, which is similar to the feeling of background cloth used in the studio. If you use average metering, the surrounding environment will be clearer and your face will look pale because of overexposure.
