What should I pay attention to when taking portrait photos on sunny days?

Many people like to go out and take pictures on sunny days, thinking that "the light is good" and it is suitable for taking pictures. In fact, the direct sun is not a good friend of photography. If you don't pay attention, you may take bad photos. There are basically three main directions for shooting in the sun: the sun is on the front, back and side of the model. 1. When the sun is on the front, the sun shines directly on the model's face. Dazzling glare will make the model squint. People with deep eye sockets will cast a heavy shadow on their eyes, so try to avoid frontal shooting. 2. When the sun is on the back, it is a backlight photo that many people like. It should be noted that at this time, the background is very bright and the light on the face is insufficient. You need to use a flash or a reflector to fill the light on your face, otherwise you will take a picture with a dark face and a bright background. When the sun is on the side, there will be a transition between light and shadow on people's faces, which is a common light in portrait shooting. Different from the angle of the sun, the light and dark areas on the face will be different. You can try more according to your own ideas. It should be noted that the dark part under metering may also have the problem of excessive shadow. At this time, you can put a reflector on the side facing the sun to make up the light.
