... this is very simple. First use diffuse light or reflected light, in short, it is softer light. Of course, the sun is not good. Sunlight belongs to direct light, which is too hard, and then direct light will make objects easy to overexpose. Use a large aperture and a long focal length when shooting. If it's macro, use a large aperture. Then you took a picture of it. Even better. Of course, grasp the exposure well, and use the maximum aperture and maximum focal length when there is no space.
