I believe that filmmakers who often mix in the photography circle have learned that the polarizer is an indispensable filter for landscape photography, and is often used to shoot glass reflections and improve the saturation of the picture.
Ordinary polarizers are composed of two filters, which are designed to rotate and adjust the polarization angle, so the two glasses will be stacked on top of each other, affecting the image quality or vignetting is an inevitable problem for all polarizers.
Nowadays, with a magnetic polarizer, this problem can be solved, which is not only convenient to be photogenic, but also has a thin frame to avoid problems such as vignetting and light leakage.
The manual measurement of this magnetic polarizer of Meigao is about 2About 4mm, the effect of improving the image quality is very good, superimposed on other filters such as filters can not only increase the ** time, but also make the color more transparent and clean, and complete a more textured landscape blockbuster.
After testing, as shown in Figure 3, compared with ordinary polarizers, this color cast has no problem at all (the picture on the right is the magnetic CPL of Meigao), and the magnetic attachment is also very firm, and it will not fall easily.
