偏振镜是摄影师拍摄中常用的滤镜之一,尤其对于风光摄影爱好者来说,偏振镜几乎是拍摄的必需品。偏振镜的作用是只允许极化方向与偏振镜相同的光线通过,过滤掉其他各个方向的自然光。普通摄影者无需弄清楚偏振镜的原理只需要知道偏振镜的用法就可以了。偏振镜的典型用法有几种:首先是用于消除非金属表面的反光,使透明体恢复透明、或使被摄物的色彩显得更加饱和。其次是偏振镜可以过滤掉天空中的部分自然光成分,只允许偏振光通过。可以使天空显得更蓝,色彩更深。
Polarizer is one of the filters commonly used by photographers to shoot, especially for landscape photographers, the polarizer is almost necessary for photography. The role of the polarizer is to allow only the polarization direction of the same light through the polarizer, filter out the other natural light in all directions. Ordinary photographers do not need to figure out the principle of polarizer only need to know the use of polarizer on it. There are several typical uses of polarizers: first, to eliminate the reflections of non-metallic surfaces, to make the transparency transparent, or to make the color of the subject appear more saturated. The second is that the polarizer filters out part of the natural light in the sky and allows only polarized light to pass through. You can make the sky look bluer and deeper.
