What's with the camera shooting two shadows?

The two shadows captured by the camera may be caused by refraction, reflection or diffraction of light. When light passes through complex objects or surfaces, they will be reflected at different angles and intensities, resulting in multiple shadows. In addition, if multiple light sources illuminate the same object, multiple shadows may also be generated. If you want to avoid this situation, you can try to change the direction or angle of the light, or adjust the position and angle of the camera to get a clearer image.
