Can a polarizer take portraits?

Polarizer can take portraits, and it works well if it works.

Polarizers are generally used to eliminate flares on metals and other objects, and are mostly suitable for shooting sky scenes, objects in clear water, still lives, and things behind through glass.

When taking a portrait with a polarizer, the effect is good when there are multiple off-board flashlights. Need more practice, find the right angle of light reflection, and the portrait will have unexpected beauty.

Simply put, cpl is to reduce the disharmonious reflected light, such as non-metallic reflection and water surface reflection. Its initial function is to make the sea or sky bluer and more transparent, which is convenient for landscape photography. In portrait photography, the polarization of the subject is generally not much, which will reduce the light of the eyes and is not recommended. For wide-angle portraits, it can be used appropriately so that the background is not exposed.

After installing a polarizer, the amount of light entering the lens is reduced by about two times. Because the amount of light entering is reduced, the corresponding camera detects less light (sunny days are like cloudy days), and the exposure time and shutter speed will be automatically adjusted accordingly, without adjustment and compensation, and the face is the same as usual.

As long as the polarizer is turned to an appropriate angle (the effect can be easily seen from the viewfinder), it should be noted that the best effect of using the polarizer is that the shooting direction is at right angles to the direction of sunlight. Using polarizers when shooting at the seaside can not only make the sky more Yun Lan and whiter, but also effectively reduce the reflection on the water and take beautiful photos.
