Natural light spreads straight in waves in all directions. Pure sunlight is polarized and has high color purity. As it passes through the atmosphere, some of it is scattered, forming a blue-gray haze that overlays all the colors. This proportion can often be weakened using polarizing filters. impede. If light now falls at a flat angle of approx. 35 degrees on a reflective surface, such as water, glass, plastics, paints (with the exception of metallic surfaces), the light is reflected and polarized. If a correctly oriented polarizing filter is used, the reflections are absorbed and the pure colors can be reflected on the film or recording chip. Water surfaces become transparent, the blue cast caused by the sky polarization is muted, and the colors become much stronger and richer. Heliopan p.
