The filter that can eliminate reflection and enhance the effect of blue sky and white clouds is a polarizer.

Polarizers are also obviously different from color temperature adjustment filters and color compensation filters used in color photography. The polarizer does not change the color temperature of the light source, and generally does not affect the overall tone of the image formed by various unpolarized colors in the scene.

In which a polarizer is used.

1, clear sky Wan Li, wants to make the blue sky bluer.

2, clear blue sky, blue sky dyed all the scenery with a layer of blue. I want to eliminate the blue in the scene and make it more saturated.

3. When shooting an object in the water, the water surface reflects light and the object cannot be seen clearly. Want to shoot objects in clear water, such as swimming fish; Or trying to make the water deeper.

4, shooting still life, want to eliminate the reflection on the surface of the object.

I want to shoot something behind through the glass.

skill

1. Because the polarizer can also reduce the exposure of 1~2, it can replace the neutral gray-scale mirrors of ND2 and ND4 in some occasions.

2. It takes some skill to use polarizer. For example, when shooting the sky, you can use your right hand to orient your thumb and forefinger at 90 degrees, with your forefinger pointing to the sun and your thumb as the best shooting direction.

3. In addition, because the polarizer will lose the aperture of 1/2 to 2 when the polarization effect is the best, exposure compensation is needed, and generally the exposure of 1 2 will be increased.

4. For the reflection of the metal surface that cannot be filtered, a large polarizer can be added in front of the light source to make the light reflected by the metal polarized, and the reflection of the metal surface can be filtered by the polarizer.

5. However, when taking portrait photography, it is best not to use polarizer, because polarizer will filter out the reflection of the face and make the face lose its three-dimensional sense.
