The polarizing filter has great possibilities. Its main feature is its ability to eliminate reflections from non-metallic surfaces, which makes it almost indispensable for filming water, glass (including mirrors), enamels, jewels, plastics, etc. The filter factor is about one stop. In digital camcorders with through the lens light meters, there is no need to make any correction.By turning the filter in front of one eye, you will be able to decide the angle at which it has its best effect, and place the filter on the lens at this angle. Best results will be obtained with lateral or frontal-lateral lighting.
- Other advantages of polarizing filters
They make blue sky look darker.
They make white clouds stand out against it.
They reduce the effect of distance haze.
They reproduce green tones exactly as in nature.
They reduce the effect of ultra-violet which occurs at high altitudes and which causes considerable blueness in the film.
They create moonlight effects in films taken during the day with sunlight at 90 degree to the camera if you close the diaphragm by half, or perhaps full stop.
