Why does an image of the panel appear to left side of the actual object when the picture is taken if the lamp in a switched on state?
Modern camera lenses are an array of multiple lenses. Such designs are necessary to mitigate degrading of the image due to aberrations. We are talking about the fact that all lenses suffer from about 7 major distortions. While these aberrations are minimized, they cannot be eliminated. Each of the several lens elements have polished glass surfaces. About 6% of the light that hits a surface is reflected away. This surface reflection is the source of ghost images and flare. We coat each lens surface with a thin transparent mineral overlay. The thickness of this coat and the density of the coat reduces the tendency of surface reflections to about 2%. The coat helps, but does not eliminate ghost images. Also, the imaging chip in the camera has a cover glass for protection, and it also is coated. Ghost images are plagues we must endure.
