How to shoot a spherical mirror

Shooting a reflector is a particularly difficult problem, and the key is to solve the problem of reflection. The characteristic of reflection is that what kind of light source is used will have what kind of reflection point. There are many reflective objects, such as glass, metal, ceramics, etc. Glass reflection can be removed by polarizer, but metal reflection is not so well controlled, especially stainless steel. Their shapes can be roughly divided into plane, cylinder and sphere, among which cylinder and sphere objects are more difficult to shoot. Take a cylinder as an example, because the angle of the reflection surface of the cylinder object is that the camera lens is facing the reflection surface, and the angle of this surface can be 180 degrees, so it is difficult to grasp the reflection control. In order to shoot, sometimes we simply use its reflective characteristics to keep or deliberately reflect light to express the texture of the object. The reflection angle of the sphere relative to the cylinder will be larger, not only in the horizontal plane, but also in the vertical plane, so some objects with strong reflection will reflect the whole light spot and the surrounding scene light and shadow, forming some messy light spots on the object, which is not conducive to the performance of the subject. To solve these problems, I think it is necessary to focus on the following aspects. 1, strong light and direct light should not be used. Direct light is light that hits an object directly. Like hard light, its light source has strong directivity, and the shape, direction and size of the light source will directly form obvious spots on the reflecting surface. Although hard light is beneficial to express the hardness and texture of the object itself, reflection is difficult to overcome, so if you don't deliberately reflect light, try not to use hard light when shooting the reflector, but choose scattered light and soft light, which can also reflect the sense of space and texture of the subject. 2. Hide the light source. Try to hide the light source so that it has no obvious light source point. You can use soft cloth to enter, and the extremely strong reflector can sometimes reflect the photographer's shadow, leaving annoying light and shadow. You can dig a hole in the soft cloth, just put the lens in, release it with a cable when shooting, and the photographer hides when pressing the shutter. However, such illumination is also a disadvantage, because it is likely to paint the object milky white, which is not conducive to the surface color of the object. 3. Use reflection. For some spherical reflectors, we can put them in a specific environment to reflect the scenery in the environment and render its essential characteristics. This is also a good choice.
