What does a Camera Polarizer Lens do?

The special effect of polarizer is to effectively exclude and filter the scattered light in the beam. The light can be put into the eye visual image in the right light axis, so that the visual field is clear and natural. Like the principle of blinds, light is adjusted to the same direction of light into the room, nature makes the scene look soft and not harsh.

Now, let's look at why we use polaroids.

(a) Let the water clearly see the bottom

CPL is a necessary accessory for shooting water, waterfall, seaside, etc., because CPL can effectively eliminate the reflection, so that the naked eye can not see the bottom of the photo, bring a new feeling!

(2) Restore the level of white clouds + make the sky bluer

When there are white clouds in the photo, you will see that the white clouds are usually a piece of white, no layers, if you add a polarizer to the lens, you can make the originally dead white clouds back to their proper levels, and the blue sky will be bluer, of course, the premise is that the photo can not be over exposed!

(3) Control the degree of reflection

Although polarizers can effectively eliminate the reflection of light, but in some circumstances we want to preserve a part of the reflection, then can adjust the ring polarizer is very useful!

(4) Use as a lightening mirror

In essence, CPL has a dimming effect. Sometimes this dimming effect allows us to slow down the shutter in broad daylight or at high aperture, which is similar to the use of a dimming mirror.

(5) Make the colors brighter

When photographing flowers, green leaves and mountains, if you add a polarizer, you can reduce the reflection of the leaves and make the colors more vivid.

Let you see through the glass

One is that photographing things inside glass is annoying... Because glass is easy to reflect light, CPL eliminates this annoying problem and lets you "see through the glass."

7. Protect your lens

Although some polarizers are not cheap, they are better than your lens getting smashed, so protecting your lens is the best, but practical reason!
