Differences and uses of uv mirror, polarizer, filter and polarizer

1 has different functions. Uv mirror is a protective mirror, which filters ultraviolet rays. Polarizer is a kind of color filter, which is used to shoot reflective scenery. Polarizers, also known as polarizers, have the same function. The filter is a colored lens to filter the color of light. Uv mirror and polarizer are both filters. The picture shows a polarizer.

2. Different uses. UV mirror is suitable for shooting in seaside, mountains, snowfields and open areas, which can weaken the blue tone caused by ultraviolet light. Polarizers are often used to take colorful photos in still life photography such as flowers. It is very useful in landscape photography, flower photography and shooting some specific scenes with strong reflection. The picture shows a uv mirror.

Extended data:

1, UV mirrors are usually used to protect fragile lens coatings. UV mirror can weaken the blue tone caused by ultraviolet light. It can also eliminate the interference of ultraviolet rays on CCD, which is helpful to improve clarity and color effect. Due to the popularity of CMOS, the sensitivity to ultraviolet rays is greatly reduced, so now the role of uv mirrors is getting smaller and smaller, and uv mirrors may sometimes play a negative role.

2. The polarizer selectively filters light from a specific direction. By filtering out a lot of polarized light in diffuse reflection, the light intensity in the sky is weakened, the sky is darkened and the contrast between the blue sky and white clouds is increased. Look at the viewfinder and rotate the front mirror when shooting. In the viewfinder, the effect is most obvious when the sky is darkest, and the difference between the darkest and the most appearance is 90 degrees.

3. The filter plays the role of "seasoning". If you can use filters flexibly, you can improve the performance of photographic works. Using filters in black-and-white photography can change the tone of the scene and make the photo closer to nature. The use of filter in color photography can change the color temperature of light source, the color of the subject or play a special visual effect.

4. Polarizer, also called polarizer, referred to as PL mirror, is a kind of color filter. The achromatic function of polarizer is to selectively let the light that vibrates in a certain direction pass through, and it is often used to eliminate or weaken the strong reflection of non-metallic surface in color and black-and-white photography, thus eliminating or reducing the light spot.
