Heliopan 77mm SH-PMC Circular Polarizer Glass (707746) Lens Filter

Polarizing filters, are color neutral and increase picture taking possibilities with black and white or color film. In color photography, unlike black and white photography, there is no possibility to change contrast or color saturation with colored filters. To do so would also change the colors in the photograph. Natural light spreads in a wave form in all direction. Sunlight is polarized and has a high color purity. When passing through the atmosphere a part of it is scattered, which results in a blush gray haze over all colors. This effect can be reduced or eliminated by using polarizing filters. If, in addition, light falls at an angle of approximately 35° onto a reflecting surface, e g. water, glass, plastic, color surfaces, with the exception of metallic surfaces, the light becomes reflected and polarized. If one uses a properly orientated polarizing filter, the reflections are absorbed and the true colors can reach the film. Water surfaces become transparent and clouds are more saturated. Minimize
