Polarizer in the most common general exterior line polarizer (PL) and the circular polarizer (CPL). Polarizer generally consists of two parts, the rear with a thread and the camera is connected to the front-end filter part can be rotated by changing the angle of rotation to reduce the passage of the polarized light. Its working principle can be understood as: the natural light in the reflected light of the subject matter and the polarized light enters the front of the camera, the role of the PL, harmful polarized "filter" natural light part and "transformation" for the polarization light, the light entering the lens is actually polarized light; reflected light in the role of the CPL, polarized light to be "filtered out" change through and on the part of the natural light to polarized light and polarized light and then circle rotation "about," transformed "natural light, the light entering the lens is actually natural light. CPL than PL is more complicated, and this is both the main reason for larger price differences.
Polarizer adjustment as follows: polarizer installed in front of the camera lens, while slowly rotating polarizer side of photo features in the polarized light source observed through the LCD screen or viewfinder, until the reduction or disappearance of the expected results so far; polarizer can also be the first directly on the front side of the viewfinder side rotating polarizer until the polarized light reduction or disappearance of up to the expected size. Remain unchanged (ie, under the premise of the direction indicated by signs on the edge of the polarizer remains unchanged), the polarizer pan and then in the orientation of the polarizer, set in the camera lens front-end. Since then, the camera can not be free to change the shooting position, otherwise you have to re-adjust the polarization direction of the polarizer.
