What kind of wide-angle lens should I choose to shoot cos?

The advantages of teacher A Zheng's use of wide-angle lens to take portraits are as follows: 1. The deformation characteristics of wide-angle lens can be used to modify the figure of the subject. 2. We can use its perspective deformation characteristics to enhance the tension of the picture and the impact of the theme. Camera/Nikon D3, lens /17-35mmf/2.8D, focal length/／17mm, aperture/f/4, exposure time/1/1s, ISO/2, flash/None When taking this photo, the photographer was very close to the model. Only by using this method can the model stand out from the picture and show its charm. The foot position of the model is very close to the bottom of the picture, so that the stretching effect can be well played. How to show the tension of wide-angle lens? To show the deformation tension of wide-angle lens, the most important thing is to take a close shot. The so-called wide-angle lens should be close, which means that the wide-angle lens should be close to the target. A senior photographer once said that if you don't shoot well enough, it's because you're not close enough. There are many explanations for this sentence, but it means that if you don't use your wide-angle lens well enough, you won't be able to shoot any features. It's not because of your lens, but because you are not close enough to the subject. Disadvantages of wide-angle lens: 1. If the deformation is not well controlled, the picture will be very strange. 2. It is not easy to highlight the main body. 3. The lens with wide viewing angle should pay attention to keeping the picture clean, which will increase the difficulty of composition. When shooting with a wide-angle lens, being too far away from the model will make the subject not stand out, and bringing in too much background will make the picture look too messy. When shooting with a wide-angle lens, in addition to mastering the distance, the angle of view is also very important. In fact, no matter what shot, the angle of view is very important, but it is particularly obvious in wide-angle shots. When shooting with a wide-angle lens and emphasizing the breadth and tension of the picture, you can shoot from bottom to top. At this time, the tension of the picture is the strongest, and the extension and diffusion of lines have the most impact. If you want to get a clean picture, shoot it from top to bottom, and then you can get the cleanest and purest picture. When using a wide-angle lens, the photographer is forbidden to stand, and the model is also standing, so it is easy to take a messy picture, and the photo looks like the model is standing in front of the background paper. You can get a clean background by shooting from top to bottom and matching a large background with the same color. When the background is clean, the object of shooting will be prominent, so it is easy to highlight the theme of shooting. Using the deformation of the wide-angle lens to modify the leg shape of the model, the general photographer uses the wide-angle lens for a great purpose when shooting portraits, that is, he hopes to use the deformation of the wide-angle lens to make the model's body shape more slender, especially to make the legs very long. Of course, there is a knack for this. It is possible to make a model with five heads into nine body if it is used well, but it is also possible to make a model with five heads into nine body if it is not used well. If you want to use a wide-angle lens to shoot the model's legs very long, the prerequisite is to use vertical composition. Because of the characteristics of the lens, horizontal composition will flatten the model, and it will fail half before shooting. When shooting with vertical composition, the picture can be divided into three equal parts. Usually, the photographer will place the model's head and body in the middle of the picture. When shooting with wide-angle lens, the deformation of this area is the lightest. Although we want the model's legs to be longer when shooting, we don't want the model's head and body to be deformed, so putting the head, hands and body in the middle can minimize the deformation. Then place the model's legs in the bisection below the trisection screen. The deformation of the wide-angle lens is stretched up, down, left and right from the middle, so you can easily shoot the legs very long by placing the legs in this part.
