Parents who pay attention, pay attention, because the system does not have the background Taobao 95MM this size. So '86MM and above' this is 95MM yo. Please parents who take the time, take note yo. Do not mistake it. I made a mistake it will be wrong. no way to use the wrong parent proud.
1, when using a polarizer, due to the need to rotate the filter, inconvenient to use the hood, the camera should be shot in shadow;
2, after you install the polarizer, will reduce the amount of light through the lens, (ie be equivalent ND4 dimming mirrors to use.
3, CPL polarizer and the reflecting surface (windows or water) into a 30-40 degree angle used in the elimination of reflection to get the maximum effect, and a 90-degree angle (straight to the reflecting surface) Use effect little or no effect.
4, in order to increase the concentration of blue color when the sun is 30-40 degrees in the sky, while the camera directly to obtain maximum results to sunlight polarizer. (Need to shun light situations) the noon sun in the head with the ground or outcomes 90-degree angle, then the effect of the polarizer is minimized. these effects from the camera's viewfinder is easy to see. check the effect by simply rotating polarizer.
CPL using some of the problems and answers:
Blurry image 1. Use a polarizer.
A: If the room is poorly lit, the focus will be prompted to fail, guests can make recommendations to the light more adequate place to try it.
Scope and occasion 2.CPL use:
1) Elimination of stray light;
2) the dimming effect;
3) Elimination of the surface reflection;
4) to make the sky bluer, the water is more type;
5) Elimination of dust in the air with water vapor, so that transparency is better.
Use of light or angle 3.CPL
1) smooth light - good
2) diffuse light - good
3) Backlight - in
4) with the sun 90 degrees (opposite the Sun) - Best
5) a 45 degree angle with the sun - good
6) at the sun or accessories - poor
4. How to see if by the rotation of CPL achieve the desired effect?
A: When the theme of the film surface to eliminate stray light is partially (half or whole), usually a little darker.
5.CPL will never age?
A: Although it will not be obvious, with 10 years in general should not be a problem.
6. Do you want to use CPL UV lens removed?
A: The more the lens will be best to remove the phenomenon of refraction, which is less prone to vignetting.
7. How polarizer turn?
Preferably counterclockwise, clockwise will turn more loose, and may even lead to falling polarizer.
