B+W Polarizing Filters remove distorting reflections of light, increase color saturation, and in addition increase the contrast. In nature and landscape photography, the use of a polarizing filter conduces to a deep blue sky, brilliantly white clouds, and vivid colors in the case of flowers. It is also ideal when photographing reflecting surfaces of water. The numerous possibilities of application apply both to black-and-white- and color photographs, and in digital photography as well. Results obtained with polarizing filters can be enhanced with the use of additional filters. A light blue conversion filter (KB 1.5), together with a pol-filter, can make cloud formations bright and sunny, and give the whole picture a cheerful character. By contrast, a weak red conversion filter (KR 1.5) can produce a dramatic, stormy mood in a color photograph. The B+W Redhancer intensifies the orange, red, and brown colors of the subject. For that reason, it is the ideal filter for, e.g., for landscape photography in autumn. Experienced photographers consider polarizing filters to be the most important filters. Their ability to reduce or eliminate reflections is probably their best-known feature, but it is not the only one. They enhance the color purity of the subject (increased color saturation) by blocking the blue veil of light from the sky, They increase the contrast in black-and-white photographs, reduce haze, and make white clouds stand out dramatically from an intensely blue sky. When the filter is rotated by 90º from its normal reflection reducing position, it can even appear to increase the relative intensity of reflections on water, glass, lacquer and plastic materials up to a factor of 2. |
