he principle of action of camera polarizer lens

The principle of a camera polarizer lens is to filter light in a specific direction by utilizing the characteristics of polarized light, in order to improve the shooting effect. Polarizing lens, also known as polarizer, is usually laminated with polarizing film, inner protective film, pressure-sensitive adhesive layer, and outer protective film, and has the function of shielding and transmitting light.
The working principle of polarizing lens
The working principle of a polarizing lens is based on the polarization phenomenon of light. When natural light encounters the surface of an object, some of the light rays will be reflected, forming polarized light. Polarizing lenses can selectively filter out these polarized lights, thereby changing the shooting effect. Specifically, a polarizing lens can adjust its filtering effect on light by rotating the lens. When the reflection disappears, it indicates that the polarization effect has reached its optimum, and at this time, photos with sharp contrast and saturated colors can be taken.
The main function of polarizing lens
Eliminating Reflection: Polarizing lenses can eliminate reflections from smooth surfaces such as water and glass, making the subject clearer.
Improving color saturation: By reducing the scattering and diffuse reflection of polarized light, the colors of the scenery become purer and more vibrant, especially the blue sky and green leaves.
Adjusting sky tone: When shooting landscapes, polarizing lenses can reduce polarized light in the sky, making the blue sky darker and white clouds more prominent, increasing the contrast between the sky and ground scenery.
Reduce the amount of light entering: Polarizing lenses can reduce the amount of light entering the lens, slow down the shutter speed, and have a similar effect to ND filters.
Absorption of stray light: It can absorb the stray light reflected by fog or dust in the atmosphere, making the captured image purer.
Usage scenarios and effects
Polarized lenses have significant effects in various shooting scenarios:
Landscape photography: When capturing natural landscapes such as blue skies, oceans, and lakes, polarizing lenses can significantly enhance color saturation and contrast in the image.
Still life photography: When capturing still life or products, polarizing lenses can eliminate surface reflections, enhance texture and detail.
Architectural photography: When capturing ancient buildings, polarizing lenses can filter out stray light, making the contours and details of the buildings clearer.
Indoor photography: In indoor environments, polarizing lenses can eliminate reflected light and improve shooting quality.
