What is polarized Sunglasses

Polarizer can be divided into three types, namely straight polarizers, ellipse polarized and round polarizers.Generally, the so -called polarizer refers to the straight line polarization, also known as flat polarization.The vibration of this light wave is fixed in a specific direction. The transmission route in the space is a sine curve, and the projection on the plane of the vertical dissemination direction is the straight line.

The plane composed of a straight polarized vibration direction and the direction of propagation is called the vibration surface. It is vertically vertically from the vibration direction and the surface of the dissemination direction is called polarizing surface.Make nature light through polarizing mirrors, and can obtain straight -line polarizers, which are often used in crystal optical research.

The classification of polarizer

1. According to the material, it can be divided into: glass mirror of glass material, resin material polarized Sunglasses, and TAC lens material polarized Sunglasses.

2. It can be divided into: Ski mirror, fishing mirror, polarized driving mirror, outdoor sports mirror, golf glasses.

How to distinguish between Sunglasses and polarized Sunglasses

The first is the relationship between the two. The Sunglasses include polarizing mirrors, and polarizing mirrors are a kind of Sunglasses.It should be said that polarizing mirrors are a special Sunglasses designed with more and more requirements and designed.

Then let's talk about the difference. As long as we do not specifically pointed out, we generally have some Sunglasses that only have the two basic functions of obstructing strong light and worry about ultraviolet rays.Such Sunglasses are relatively single, the technical content is lower, and of course the cost is lower. Now many merchants sell ordinary Sunglasses as polarizing Sunglasses, which harms many consumers.

The biggest difference between polarized Sunglasses and ordinary Sunglasses is that this Sunglasses are treated with reflected light.In the environment of our lives, there are three kinds of light: direct light, reflection light, and shot light. Among them, we can not perceive the light shot light, but it is the most important light of our eyes that can see objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see objects.Direct light has a fixed light source (such as the sun), as long as it pays attention, it will not cause harm to our lives.

Only reflected light, because Smooth and flat planes can become reflexes. These common reflexes often reflect light suddenly, which will bring a lot of inconvenience to our lives.For example, driver drivers, the rearview mirror ahead is an uncertain reflective light source. The surface of the road on the road or the Smooth plane objects carried by passers -by can become a reflected light source. These reflex light may bring the driver of the driver.It is dangerous.

Polarized Sunglasses are the glare of reflected, filtering it, so that it can play a role in anti -dizziness, and traveling in summer will make the field of view more clear and reduce visual fatigue.Of course, such Sunglasses will also be much more expensive.

If you just go out, ordinary Sunglasses can fully meet your needs.But whether it is driving or outdoor activities such as mountain climbing and skiing, choosing a pair of polarized Sunglasses will make you easier and more comfortable.

When is it suitable for wearing polarizers

1. fishing

In summer, fishermen like to wear Polarized glasses.Why?The reason is very simple. Polarized Sunglasses have the effect of filter polarizing light. It is easier to wear fishing, and it is easier to watch.It feels more comfortable.

2. Driving

Polarized lenses are the most recognized lenses in the world.When the surface is reflected by the object, it is partially polarized and has a glare.The negative effect of glare -enhances brightness and weakens color saturation; the outline of the object is blurred, making glasses fatigue and discomfort.Polarized tablets make the polarization principle of light, which can effectively eliminate the special functions of glare, filter the messy light, improve the driver's vision and add fun to drive.

3. outdoor sports

Friends who love Outdoor leisure tourism are also exclusive to polarizing lenses. The polarizing mirror is composed of a balanced crystalline. This structure only allows the light waves to balance the crystal, and the light waves that shake to other angles are blocked.If the angle of the polarizer is adjusted, the shocking light reflected by the water surface, glass, flowers, water, water and other reflection can be blocked, and normal light can be partially passed, so as to enhance the contrast, reduce reflection, enhance the color of the scenery, reduce the atmosphere of the atmosphere,The role of fog phenomena makes you see the clearness of the world, and return you a colorful world, a blue sky, strong and beautiful nature.

The lens polarization angle and arc are specially designed and processed. The wearer will not have the feeling of distortion and dizziness of the scene. The resin polarizing lens has the advantages of lightness, difficulty in breaking, and easy to wear and comfortable.It is most suitable for fishing, driving, exercise, navigation, skiing, hunting, etc.

How to buy polarized Sunglasses

1. The first consideration is the quality of polarized Sunglasses

The primary function of polarizing Sunglasses is to prevent ultraviolet rays and filtrate polarized light. Good polarized Sunglasses lenses can block more than 90%of ultraviolet penetration. Please choose polarized Sunglasses with the best blocking of UV400 to the best obstruction of ultraviolet logo;The inferior polarization Sunglasses of the polarizing filtering function, such as dark Sunglasses, is darker with the light of the human eye and the pupils of human eyes will become larger, and the ultraviolet rays of the eyes will increase, increasing damage to human eyes.

2. Will there be discomfort for a long time?

Genuine polarized Sunglasses must be comfortable to wear. If you feel uncomfortable, dizzy, headache, dry eyes, tingling, etc., please take it down quickly;

Meicoscopy belongs to inferior or imitation generally causes dizziness and headaches. Generally, inferior lenses are not technical and functional when manufacturing.The damage can be described as a loss.

3. Focus on the protection function of the frame

The protection function of polarizing Sunglasses Apart from the basic functions such as anti -ultraviolet rays, avoiding strong light dazzling, and filtering glare, most polarizing Sunglasses frames are designed with surface arcs. In outdoor sports, it can effectively prevent wind and foreign body stimulation. In additionThe hardness of the lens and the flexibility of the frame of the frame must be considered whether it will hurt the human body.

4. Polarized Sunglasses should be true and natural

The color selection of polarized Sunglasses should be based on the color of the surrounding environment, the edges of the object are clear, and the principle of effectively identifying different color signal Lights.Especially when driving Sunglasses, it is guaranteed to drive safety.The color of the lens is better in gray, tea, and green, because these colors of lenses are better absorbed by infrared and ultraviolet rays, which can improve visual contrast and clarity. Wearing effects in severe air pollution or fog.

How to identify the quality of polarized Sunglasses

1. Generally, there will be instruments that detect Sunglasses to resist ultraviolet capacity. You can know if the glasses in your hands meet the standard through instrument detection.

2. The simple way to test the quality of the Sunglasses is: you can use the ultraviolet light issued by a banknote pen or a banknote check machine to observe the UV logo pattern on the RMB through Sunglasses. If the quality of the Sunglasses is poor and there is no blocking of ultraviolet rays, it can still be clearly clear.When you see the UV logo pattern on the RMB, on the contrary, if the quality is excellent, you can't see it.

1. The matching method of Fish drift and lead pendant

The use of Fish drifting and lead pendants is a very important part of fishing. Their combination can affect the effect of fishing.Generally speaking, the size and shape of the float should be matched with the fish species and waters of fishing, and the weight of the lead pendant should be selected according to the size of the float and the intensity of the water flow.The following is the combination of some common Fishing floats and lead:

1. Small floating and small lead pendant: suitable for light water or water flow, such as fishing catfish, grass carp, etc.

2. Large float and large lead pendant: suitable for deep water or strong water flow, such as carp fishing, catfish, etc.

3. Long float small lead pendant: suitable for remote shots, such as fish fishing, sea bass, etc.

4. Short floating drifting large lead pendant: suitable for situations that need to sink quickly, such as carp fishing, catfish, etc.

5. Sinking floating lead pendant: suitable for placing bait on the bottom of the water, such as carp fishing, catfish, etc.This matching method can make the bait more naturally present on the bottom of the water, increasing the success rate of fishing.

6. Drifting floating lead pendant: suitable for drifting in the water, such as fishing bass and sea bass.This combination can make bait more naturally drift with the water flow, increasing the success rate of fishing.

7. Drinking lead pendant: It is suitable for fishing on the surface of the water or in different depths of fishing, such as fishing catfish, grass carp, etc.This combination allows the fisherman to adjust the depth of the float as needed and fishing more accurately.

The combination of Fishing floats and lead pendants needs to be selected according to the specific situation. Only reasonable matching can improve the effect of fishing.

2. What is the distance between floating and lead pendants

The distance between the lead pendant is far away, which will affect the speed of the floating rollover. So how much is the distance between the Fish drift and the lead pendant?

Generally speaking, the distance between Fish drifting and lead pendants can be adjusted flexibly. For novices, the distance between the two should be controlled at about 30 cm, and then the fish hook is hung on it, the drifting seat is plugged in the float, leaving 5 mm in the middle of 5 mm.In the space, put the fishing rod in the water, and slowly trim the lead Skin until it is trimmed to the appropriate number of messengers. When trimming to the six eyes, hang a double bait on it, and leave it at a glance.

[Method for polarizing mirror] How is the main purpose of polarizing mirror in polarizing mirror?

How to use Polarized mirror

There are two types of polarizing mirrors: round polarizer (Referred to CPL ) Line polarial mirror (simply referred to PL or LPL To.

They are in most consumer digital cameras (DC ) There will be no difference in upper. TTL Light metering function) SLR/DSLR Also DC And hope to share a polarizing mirror, it is best to choose a round mirror.In addition, the differences between line polarizers and round polarized mirrors, as well as why in modern times SLR/DSLR The reason to use a round Polarized mirror, in the clumsy book L.6 Zhang has a very careful explanation; but because it is not important for novices, it is omitted here. Interested friends, please refer to the clumsy book (there is a chapter in the link above PDF files).

There is a loop that can rotate freely on the Polarized mirror. Its function is to regulate the effect of polarizing mirror.The polarizer is usually two types: thick (general) type and thin type. The former may be thicker than the latter1mm Or more, when mentioning polarizers below, if there is no special explanation, it refers to thick (or general) polarizer.The thin Polarized mirror is for wide -angle or ultra -wide -angle lens, because too thick polarizing mirrors can easily produce dark corners.Generally speaking, if the camera lens ( 135 Movies) The equivalent focal length is at 35mm Above (including 35mm ), Thick polarizer should not have a dark corner; but if the focal length is less than 35mm The thick Polarized mirror is likely to produce dark angles, but this is usually related to the optical and mechanical structure of the camera mirror. It may not be the case for every lens, so it is best to try it before buying a polarizer.

The main purpose of polarizing mirror:

Reduce the reflection of glass, water surface, and non -metal surface, make the sky blue, and improve the saturation of the color of the picture.Because the Polarized mirror is dark gray, it will block part of the part that can reach the sensor chip Light, it will generally decrease1 arrive 1.5 Between Levels.In addition to the full manual exposure mode, the camera's optical metering system of the camera will be adjusted by itself in other (such as aperture prerequisites, or the shutter prerequisite) mode, but you still have to check whether the aperture or shutter speed selected by the camera will be used.

Reduce reflection

The reflection on the surface of the subject will wash away the details of the picture, or change the color of the picture. One of the most important functions of the polarizing mirror is to reduce or even eliminate the light that is reflected by the camera and enter the lens, but when the subject is metal, Polarizer The function is not very significant.The best angle of lowering or eliminating the reflection with a polarizer is that when the light source's irradiation angle and the camera shooting angle are made with the camera30 On the occasion, one (or two) deviates from 30 The time -effective use will be reduced, and the more effective the angle deviation is, the lower it will be.It is very simple to reduce the reflection with polarizers.After the composition is completed, rotate the ring in front of the Polarized mirror, and watch the scene window (or LCD/EVF ) The effect of polarizing mirror will be displayed. Once the desired effect is obtained, stop rotating and shooting.It should be noted that polarizing mirrors are not universal, and it is likely to be unable to completely eliminate reflection.

The most well -known application of polarizing mirrors is to deepen the blue of the sky, making the blue sky and white clouds stronger; however, if the sky is not blue (such as a cloudy day), no matter how good the polarizer is, the blue sky cannot be shot.But we should It is time to understand that only one of the sky will become bluer, and the other may not change. More importantly, the shooting angle must be selected correctly.There is a very simple rule for choosing shooting angle, first extending the index finger To the sun, then erected the big fingers vertically with the index finger, and turning around the index finger, so the direction that the Mark finger passes is to get the most effective shooting direction; in other words, the best shooting direction and the direction from the camera to the sun to the sun Droop straight!Please pay attention, the Mi fingers passed by360 Degree, except for the middle of the right, this time, this 360 Some parts in the sky, part of the ground to the ground, to the sky is the direction that can turn the blue and become blue.When the camera deviates from this direction (such as the shift in the sun or the anti -sun direction), the lower the effect. If it is more than a certain angle, the effect will not be significantly or even disappear.After looking for the direction of shooting, slowly turn the ring in front of the polarizer, and take the shutter after getting the expected effect.

In addition, because polarizing mirrors will reduce or even eliminate the reflection of the subject, the color of the picture shot with polarizer is also more pure than it is not in time, and the contrast is also higher. This is the theme of the next section.

increase the saturation of contrast and color

The reflection of the subject will cover up the original color and details. If the reflex characteristics of the subject in the screen are similar (such as the leaves), a faint reflection not only erase the original color, but also reduce the contrast of the picture. In this Affection In the case, the use of polarizers has the effect of reducing reflection, reproducing the color of the subject, and improving the comparison of the picture.The lower left photo is added with a polarizer but the lowest effect is used, and the lower right is the maximum effect; these two are extremely strong In contrast, the reflection of the leaves under the scorching sun distused the color of the woods, but to maximize the effect of polarizing mirror, and the color of the wood and the grass appeared, making the two photos very different.

If the camera cannot be equipped with polarizing mirror?

Many small and stylish digital cameras can neither install filters nor adding sleeves, but we can hold a polarizer in front of the camera to shoot, but how to adjust the effect of polarizing mirror?The method is very simple. First of all The direction of the mirror on the shooting of the lens (so the closer to the camera, the better), see the lower left photo; then turn the ring on the Polarized mirror, stop after the expected effect (below); finally move the adjusted polarizer to the lens to the lens Ahead (below Right), but the polarization mirror cannot be rotated, because once the direction of the polarization mirror is changed, the desired result is not available.

Practice this procedure several times, and try to take some photos to compare the results of use without polarizing mirrors. After several times, they will be handy.Most lightweight digital cameras have a small diameter, small,37mm The Polarized mirror is usually large enough (if it is suspected 37mm Too small, just use it 43mm ; 37mm Too big, try to try it 28mm ), Bring a polarizer with you, you can easily take photos with saturated color, blue sky and white clouds, and high contrast during travel.

precautions for using polarizers

First, polarizing mirror may be the most important filter in digital photography. It can reduce or even eliminate the light reflected by the subject, turn the sky blue, improve the saturation of the comparison of the picture and color.

Second, most consumer digital cameras can use line polarizers, but the vast majority (especially those with autofocus and metering function)SLR/DSLR You can usually only use a round Polarized mirror.If a Polarized mirror is used at the wide angle end, a thin Polarized mirror should be used.

Third, the use of polarizers will lose1 arrive 1.5 Grade light will affect the aperture or shutter speed of the selected; in other words, it is likely to use a large aperture (so the depth of the depth of the scene) or the slower shutter speed (then the movement of the movement It may be blurred and easily shake the camera), so you should pay attention to the aperture and the shutter speed.

Fourth, although the polarizing mirror has the effect of reducing reflection and turning the sky blue, but this effect is related to the angle of shooting. If the shooting angle is wrong, it is likely that the expected effect will not be obtained.Furthermore, when shooting with a wide -angle or ultra -wide -angle lens, because the viewing angle may be greater than the best angle of the polarizer, the sky in the screen may appear from very deep to quite light, that is, the blue color with uneven concentration.

Fifth, it is best to remove it from the lens when there is no need to use a Polarized mirror.1 arrive 1.5 In the secondary light, the second is because the effect of the polarization mirror is set to and the effect is more or less, so the polarizer may sometimes cause the anti -effect (such as filtering the expected reflection).

This article introduces the basic concepts, usage, and effects of polarizing mirrors, and lists some precautions when using polarizers.The effect of polarizing mirrors is difficult to simulate post -made software, even if the sky turns blue.if The boundary between the sky and the ground is relatively simple. When the post -made system is selected, it is easier to change the color depth. Once the boundary becomes very complicated, the part of the sky is a time -consuming and laborious job. Objects, it is better to use Polarized mirror to adjust the effect when shooting.Furthermore, if the picture loses the details due to reflection, no matter how good the post -made skills are, there is no way to make the details and color that has not been recorded. Come.For these reasons, polarizing mirrors are a filter that cannot be completely replaced by post -made software.
