What is a polarizer? What's the difference between it and a UV mirror? What is the function?

Polarizer can eliminate part of the reflected light and improve the clarity and expressiveness of the captured image. It can eliminate the light reflected from bright surfaces such as water or glass. In addition, it can also increase the color saturation, so that the colors of blue sky, green leaves, ridges and buildings are more vivid.

UV mirrors are uv-proof, such as taking pictures in mountains and snow. But now the CCD of digital camera generally has anti-ultraviolet coating. Therefore, the current UV mirror basically only plays the role of protecting the lens.

Just choose a brand, such as Kengo. According to the caliber, the price is generally around 200 to 400 yuan. The price of high-end brand B+W is between 800 and 2000 yuan.

What's the difference between UV mirror, filter and polarizer?

UV mirror and polarizer are both filters.

The function of UV mirror is to filter out ultraviolet rays. In today's digital age, ultraviolet rays have little effect on imaging. So its role is to protect the lens.

A polarizer can filter out the light at a certain angle ... for example, patting a stone at the bottom of the water, and you can use a polarizer to filter out the reflection in the water.

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

UV used in digital fuselage is basically equivalent to protective mirror.

Polarizer, also known as polarizer, abbreviated as PL. General circular polarizer, abbreviated as CPL, is used to reduce polarized light, reflect light, increase color density, and reduce light brightness to some extent. There are two lenses, which should be rotated when used. The filter is colored, such as red, orange, green, etc.

The differences and uses of ultraviolet reflector, polarizer, filter and polarizer are discussed.

Nowadays, UV mirrors are only protective lenses, and many people also use polarizers to replace them, only to remove them in some unusable occasions.

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

The function of the UV mirror is to filter out the ultraviolet rays in the sunlight and reduce the appearance of purple edges in the photos. But now most people wear anti-ultraviolet glasses mainly to prevent collision and skid. Especially those cheap UV mirrors are actually a piece of glass.

Polarizer and polarizer are one thing, and the amount of refracted light entering the mirror can be adjusted by changing the angle of the filter. It is very useful when shooting water, mirrors and reflective metal surfaces.

Filters are mainly monochrome mirrors and gradient mirrors, most of which are used to adjust the white balance. I use less and feel useless.

There is also a medium gray mirror, also called reduction mirror. Used to reduce the amount of light, mostly used to shoot slow doors.

The differences and uses of uv mirrors, polarizers, filters and polarizers have never been clear.

UV mirror is used to protect the lens, mainly a piece of glass.

Polarizer and polarizer are the same thing, which is used to reduce the amount of light entering in a certain direction. The effect is that the sky will be bluer and the reflected light on the water surface can be removed.

Filters, also called filters, are the general names of those above.

What are the functions of UV filters and polarizers used in cameras?

UV mirror is also called ultraviolet filter, which is ultraviolet light. Many people buy UV mirrors to protect the precious lens coating, which is actually only an accessory function. UV mirror can weaken the blue tone caused by ultraviolet light. At the same time, for digital cameras, it can also eliminate the interference of ultraviolet rays on CCD, which is helpful to improve the definition and color effect. However, 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 ordinary quality uv mirrors may sometimes play a negative role.

The polarizer is made according to the polarization principle of light, which is used to exclude and filter the scattered light in the light beam, so that the light enters the eye visual image on the right transmission axis, and the visual field is clear and natural.

Are filters and polarizers the same thing?

Contact lens is a filter.

Polarizers are not commonly used and can filter scattered light, so they are generally not used indoors, portraits, flowers and so on.

How about a UV lens, just so-so? Suit yourself.

What are the commonly used medium gray filters? What's the difference between it and polarizer?

Neutral grey mirror, also called medium gray density mirror, or ND mirror for short, is used to filter light. This filtering function is non-selective, that is to say, the dimming ability of the nd mirror to light with different wavelengths is equal and uniform, and it only plays the role of weakening light, but has no effect on the color of the object, so it can truly reproduce the contrast of the scene. Neutral gray-scale mirrors have a variety of densities to choose from, such as ND2, ND4 and ND8 (which require one, two and three exposures respectively), and can also be used in combination with multiple neutral gray-scale mirrors.

Polarizing (vibrating) mirror: it can weaken the reflected light on the surface of an object. Exterior photography can make the blue sky bluer, with sharp contrast and saturated colors. You can also reduce the reflection where there is reflection on the object. Black-and-white and color photography are acceptable. When shooting, you need to add 2 levels of exposure, which is a necessary filter for photographers.

Their differences are as follows: the medium gray density mirror weakens the light, which weakens the light input to the lens; Polarizing light (vibrating mirror) is used to reduce the reflection of objects where there is reflection. For example, when shooting leaves, porcelain and other things with large reflection, it can reduce the reflection and is not dazzling.
