What filter is good for the camera?

What are the commonly used color filters? What are the special effects after use?

Commonly used color filters are: glass sandwich filter and colored glass filter.

1, glass sandwich filter

The glass-sandwiched color filter is formed by bonding two colorless glasses and a colored film. Its advantages are high transparency, many grades of pigments made by chemical methods, high absorption and passing ability for various colors of light, and easy wiping and storage. Widely used in film photography and color enlargers, there are also many such filters in cameras.

The film sandwiched between two pieces of glass, such as damp or vibration, is easy to glue or deteriorate the lens; Two pieces of glass are thick when they are bonded together. If the glass is not polished well, it may also cause the focus of the lens to change and affect the clarity of the image.

2. Colored glass filter

The colored glass filter is made of colored optical glass with excellent texture by grinding. Its advantages are high transparency, thin grinding thickness, unchanged lens focus, and strong ability to absorb and pass various colors of light, even if it is wet and heated. This color filter is widely used in modern photography.

However, due to the color modulation process of colored optical glass, its various pigment grades are not as many as those of color film and glass sandwich filter.

Extended data

1, weak color filter

The weak color filter can only absorb ultraviolet light and a small amount of blue-violet light, and all other colors can pass through, so the absorption force is small and the pass rate is large. There is no obvious difference between the tone of the photo taken and the tone of the subject (except for color separation and blind color).

2. Neutral color filter

Neutral color filter can absorb most of the blue-violet light, with high absorption and slightly lower pass rate. Compared with the color tone of the shot scene, the color tone of the shot photo is natural and moderate, and the ideal effect is achieved.

3. Strong color filter

The strong color filter can absorb all the blue-violet light and only let some of the required color light pass through, with large absorption and low pass rate. Compared with the tone of the scene, the tone of the photo is in sharp contrast, and the adjustment of the color of the scene goes beyond the natural state.

What are the most commonly used filters for SLR cameras?

Commonly used filters are uv mirror, nd mirror, gradient mirror and cpl. \ x0d \ The main function of UV mirror in digital age is to protect the lens. \x0d\nd mirror is used to reduce the amount of light entering, which is very useful when slow door shooting is needed during the day. \x0d\ gradient lens is used to solve the problem of large light ratio, which can expose high light and dark light correctly at the same time. \x0d\cpl can eliminate the reflection of water and glass and make the sky bluer. \x0d\ There are other color filters, starlight mirrors and the like, which are not used as frequently as the above. \x0d\。 \x0d\ Dozens of filters are not recommended to be purchased and used. Originally, the lens is a very precise optical structure. Adding a glass or branch filter in front of it will definitely affect the imaging. High-end filters can also minimize this effect, but low-end filters have a greater impact on imaging, and some inferior products will also affect focusing. \x0d\。 \x0d\ You don't need to buy a uv lens for your camera lens, but you need to buy thousands of high-grade uv lenses, which are similar to yours and not worth it; Buying a low-grade uv mirror also affects imaging. The original image of 18- 135 is average, and it is even more meaningless to drop it. The filter for other effects depends on whether you need it or not. \x0d\ If you must buy it, buy a 100 Kengo uv mirror, which can be put in the camera bag when not in use. When it rains or goes to the seaside, install protective glasses temporarily. \x0d\ If you want to buy it, just buy a filter with the same caliber as your lens. 18- 135 The lens is 67mm.

How should a novice photographer choose a filter? Filter details teach you to choose!

A photographic filter is a photographic accessory. Proper use of photographic filters will make photos show better effects and bring different visual enjoyment. There are many kinds of photographic filters. How should a photographer choose a photographic filter?

Other filters (optional)

Filters are indispensable equipment in digital photography. Whenever you buy any single-lens digital camera, you will recommend a filter to protect the lens. It is generally called a UV mirror, but it is actually wrong. UV mirror is not to protect the lens, but to protect the lens. In addition to these, there are many commonly used filters, such as polarizers to reduce reflection and increase photo saturation, close-ups of macro photography and so on.

Protective glasses (not necessary)

Protective glasses are used to protect the lens coating and prevent dust, debris and water from damaging the lens coating. Will not affect the light, color, etc. It has a certain protective effect and is cheap.

Ultraviolet mirror (optional)

UV mirror, also called ultraviolet filter, is generally colorless and transparent. Due to coating, it will appear purple or purplish red when viewed from the side. The function of UV mirror is to filter ultraviolet rays with wavelength below 400 nm, which has no influence on other rays. In addition, it also acts as a protective mirror for lenses at some time to prevent the lens coating from being damaged.

UV mirror is suitable for shooting in seaside, mountains, snowfields and open areas, which can effectively weaken the blue tone caused by ultraviolet light; However, you don't need to use a UV mirror at night or in an indoor shed. At the same time, it can also eliminate the interference of ultraviolet rays on photosensitive elements, and better improve the clarity and color reproduction effect.

Photographers should pay attention to the problem of lens color cast when purchasing UV lenses, and install them in the camera to see if the wide-angle end and telephoto end will affect the focus.

CPL polarizer (necessary for landscape photography)

CPL polarizer is also a kind of filter mainly used for scene shooting, which can eliminate non-metallic reflections (such as water reflection, glass reflection, cloud reflection, etc.). ), improve color saturation (eliminate polarized light to make colors brighter), and reduce light to a certain extent (reduce polarized light and slightly weaken light).

1, eliminating non-metallic reflection

When shooting the water surface, the polarizer eliminates the reflection of the water surface and can see a shallow underwater picture; When shooting white clouds, the polarizer eliminates the reflection of white clouds, making them more layered; The problem of metal reflection cannot be solved by polarizer.

2, improve color saturation

When shooting the blue sky, the polarizer will darken the picture to improve the saturation; Reduce reflection, reduce light and improve color saturation when shooting flowers.

3. Reduce man in the mirror appropriately.

Because the polarizer eliminates the reflection and the light is dimmed by 1-2 exposure, it has a certain dimming effect.

Photography lovers mainly choose square or circular polarizers, and the square has a wider scope of application, which is the trouble point of the bracket; The circle is easy to use, but different lenses have different calibers, so the use is limited, depending on personal choice.

Gradient gray filter (necessary for landscape photography)

When taking landscape photos, you need to pay attention to the level of the horizon; When shooting scenery photos with large light ratio, it is necessary to pay attention to the exposure requirements that the sky is not overexposed and the ground is not underexposed; Therefore, the gradient gray filter is a great weapon to shoot the landscape with large light ratio.

The gradient gray filter has a gray gradient layer from transparent capitals on the lens, which can meet the shooting requirements that the sky is not exposed and the ground is not underexposed. Suitable for sunrise and sunset, beach and coast, ground sky, sea and sky, or keep some details. Simply put, it is to balance the difference of ambient light and better show the light and dark details of the picture.

When photographers choose GND, there are mainly squares and circles, just like PL mirrors.

Neodymium reduction mirror (necessary for slow door photography)

The exact name of nd subtraction mirror is medium gray density mirror, which is used to be called subtraction mirror or ND mirror in photography circle. The function of reducing mirror is to reduce the light entering the camera, which plays an irreplaceable role in shooting long exposure works.

Three elements of exposure control the exposure of the camera. When creating slow-door photography, the shutter speed is slow and the exposure time is long, which is the premise. In addition, because of noise and image quality, the sensitivity generally uses lower ISO parameters, so the problem of controlling light is adjusted by aperture. Because the exposure time of slow door photography is long, in order to keep the total exposure unchanged, the aperture can only be reduced. When the aperture is reduced to F22 and still overexposed, the exposure time can only be reduced, and the effect of slow-door photography is not obvious.

The variable diameter mirror is to solve the problem that our parameters are too exposed when they are adjusted to the extreme. Different gears of neodymium mirror reduce different exposure. ND2, ND4, ND8, ND 16, ND32, ND64, ND 128, ND256, ND5 12, ND 1000 can reduce the light exposure from 1 to/kl.

Photography enthusiasts recommend ND 1000 to reduce the exposure of 10. Wide application range, cheap and easy to use at home. Those who pursue quality can consider importing products.

abstract

1. There are many photographic filters, and you only need to buy them when you actually need them.

2. For friends who like landscape photography, CPL polarizer and GND gradient lens are essential.

3. Little friends who like slow door creation, ND reduction mirror is necessary.

4. If you often shoot during the day, it is recommended to buy a UV mirror.

There is no need to shoot other effects, and cheap protective glasses are a good choice.

What filter is used to shoot portraits?

Question 1: What filter does the portrait use? Filters are generally used for landscape photography.

There are mainly uv mirrors, polarizers, gradient mirrors, medium gray reduction mirrors, color filters and so on.

If it is an outdoor portrait, you can generally use the antireflection mirror when shooting a large aperture blur.

But at present, the shutters of high-end models are very fast and unnecessary.

Therefore, in general, there is almost no need for filters.

Of course, you should also use special ones, such as using a uv mirror to smear the forest when softening portraits. Achieve a special artistic conception. The following figure

Question 2: Do you need any filters to take portraits? Filters are usually used for landscape photography.

There are mainly uv mirrors, polarizers, gradient mirrors, medium gray reduction mirrors, color filters and so on.

If it is an outdoor portrait, you can generally use the antireflection mirror when shooting a large aperture blur.

But at present, the shutters of high-end models are very fast and unnecessary.

Therefore, in general, there is almost no need for filters.

Of course, you should also use special ones, such as using a uv mirror to smear the forest when softening portraits. Achieve a special artistic conception. The following figure

Question 3: What filter do I need to buy to get the best picture quality when shooting outdoor portraits with SLR cameras? You should first understand the purpose of various commonly used filters:

Polarizers are mainly used to eliminate the reflection of nonmetallic surfaces, such as shooting fish in the water from the side. With a polarizer, the environmental scenery reflected by the water surface can be eliminated.

UV mirror is used to eliminate ultraviolet rays entering the lens. Because the sensor of a digital camera not only reacts to visible light, but also reacts to invisible infrared rays and ultraviolet rays, the UV mirror can eliminate these influential ultraviolet rays (infrared rays will be removed by the infrared cut-off filter in the camera).

Gray mirror, used for calendering or long exposure during the day.

The gradient lens is used to shoot scenes with great contrast, such as half the sky and half the mountain. With a gradient lens, you can only calendar the sky.

The starlight mirror is used to make the light source in the night scene produce luminous effect.

Soft-focus lens, used to produce fuzzy and hazy effects.

A color filter for filtering out a specific color.

Infrared mirror, using the characteristics of digital camera sensor can sense infrared light to shoot special infrared scenery film.

These filters are common filters, and some can be replaced by post-processing methods, such as soft focus, infrared, starlight and so on. Uv mirrors are generally useless (anti-100-200 yuan's ultraviolet rays will affect the image quality). Portrait shooting only needs to prepare a large aperture fixed-focus lens (generally equivalent to 70mm- 100mm belongs to the portrait focusing section), but the filter is not a necessity.

Question 4: What filter is better for people to take pictures? Generally speaking, portrait photography does not need any filters, and it can take UV.

Question 5: What filter is the best for SLR cameras to shoot people on location? Filters are generally used to shoot landscapes, but rarely used to shoot people. If you have to choose a filter with the best effect of taking pictures, then choose CPL filter.

Question 6: What filters do you often need to play photography? What are their functions? Uv mirror: many people use it, which can effectively reduce the intake of ultraviolet rays (but it doesn't work on cmos) and prevent the lens at the front end of the lens from falling off and being scratched. However, even the best uv will have a bad influence on imaging, which will reduce the image quality and increase ghost. Therefore, personally, uv is not recommended. Spending a lot of money on a uv mirror is actually equivalent to spending money to reduce the imaging quality of your baby's lens, which does more harm than good. On the contrary, wearing a hood often can also prevent the lens from being scratched and inhibit glare to a certain extent, so the hood is harmless to the lens and imaging and will not damage the image quality.

Polarizer (CPL): the first choice for landscape photography. As we all know, reflected light is polarized light, which can be eliminated by a polarizer, so that things behind the reflective surface (such as things behind the glass window) can be easily photographed, and the color saturation of the subject can be increased because of reflection (such as the sky becoming bluer). But if it is used in portrait photography, it will have a bad effect: it will eliminate the reflection on people's faces and have no sense of hierarchy.

Medium gray filter (ND filter): It is also the first choice for landscape photography and other subjects. The purpose is to reduce the amount of incident light without changing the original color of the subject, so as to achieve the effect of slow door shooting (such as flowing water like satin, the trajectory of clouds in the sky, etc.). ), and it plays a very important role in shooting backlit portraits with flash without high-speed shutter synchronization. ND filter has this different dimming iNDex, that is, nd value. By analogy from ND2 to nd32, nd2 can only weaken the exposure of 1, ND4 can weaken the exposure of 2, ND8 can weaken the exposure of 3, and so on. I think the most commonly used medium gray filter is ND8, but CPL can also reduce the exposure of 1-2 files. So, it's up to you whether you want this neutral gray filter or not.

Medium gray gradient lens: This filter is a derivative of the medium gray filter. Its characteristic is that half of the lenses are 18% gray, and the other half is really colorless and transparent, and there is a transition at the junction between them. Its function is to balance the picture with excessive light ratio, such as the scene containing both the ground and the sky. If the light is measured by the ground, the sky will be too violent and dead white. If the sky is used to measure the light, the ground will be underexposed and become a silhouette effect. The medium gray gradient lens will appropriately weaken the exposure of the sky, and at the same time, it can roughly meet the exposure of the ground, so as to pursue the balance between the two exposures without losing the details of the dark and bright parts. However, using HDR technology and "black card jitter" (this technology can be obtained by Baidu, so I won't say much here) can also achieve this effect, even better than the effect of medium gray gradient mirror. So this filter is not commonly used, you can try it if you are interested.

Various color temperature filters and color temperature gradient mirrors: These filters used to be commonly used in film cameras, and they can adjust the white balance by changing the color temperature. However, in the digital age, these things are no longer commonly used, and occasionally someone will install or shoot some special scenes to enhance the color (digital later stage is also possible). If you are interested, you can buy some pieces from Taobao to experience it. Not worth buying.

That's all. I hope it helps you. My level is limited, please don't spray if there is any incompleteness or omission, thank you.

Question 7: 5D2 is used to shoot people or landscapes. What filter does 24- 105 of 5D2 use to shoot people or scenery? What filters are used to make them sharper and more transparent? Polarizers are mostly used for landscapes, but not for ordinary people. Generally speaking, sharper and more transparent can not be obtained by using filters, which is related to parameter setting and lighting environment, and also to the artistic level of photography. The key is to practice more. Do you use 5D2, too? How to set these parameters to make the photo effect sharper and more transparent? In terms of scenery, it is mostly small aperture and large depth of field, but it is more related to ambient light and how to take pictures. If the air is not clear, it is not easy for you to set any parameters. So photography is a paid job. In terms of scenery, we should make full use of the early morning time, so we should get up early. People are usually related to lighting, and post-adjustment is also very important. These also need more research. I also use 5D2, and I also have 24-66 in my hand.

Generally, I don't need 24- 105L to take portraits. I will choose Sigma 50 1.4 or Xiaobai first. In the wild or crowded environment, I will install a UV protective front lens. When taking pictures in the indoor shed, I will remove all the protective lenses to avoid glare.

You don't need 24- 105L to shoot the scenery. I will use 17-40L, and add a polarizer as appropriate. I will try to use f8 as the aperture to get the best image quality.

24- 105L is generally used for shooting activities, weddings and products, because it is relatively mediocre, characterized by reliability and relative portability.

Filters can't make images sharp and transparent, but they can easily reduce sharpness and produce glare (especially using inferior fake foreign devil filters)

LZ just contacted the SLR? It seems inappropriate to use 5D2 as the starting equipment. At the time of design, it is assumed that the user fully understands the corresponding meanings of all parameters, and there is almost no text description and help information, no scene mode and no guide. You must try to get used to it. 1, UV mirror or protective mirror, used to protect the lens, has been installed on the lens, this must be available; 2. Polarizer, which is the most commonly used filter, is used to eliminate or weaken the strong reflection on the nonmetallic surface;

3. Gray mirror, dimming;

4, gradient mirror, reduce the amount of light in some areas.

Buy a UV mirror first, and we can talk about the rest later. You will know more about photography and equipment. Most landscapes use polarized light, and people don't need filters.

Improve the clarity of the camera. Don't forget to come back after filming.

Permeability depends on the lens. Generally, the fixed focus is relatively transparent, and the air quality is poor.

It is recommended not to use camera parameters, the latter is more convenient.

Question 8: When someone knows what filter to use, the camera of the mobile phone is too bright and overexposed, and then the bright photo of Mito Xiu Xiu is polished and beautified, and then the retro filter is covered.

Question 9: Is Longteng's lens better than Canon's? What filter is the best for portrait shooting? Almost. It's definitely better than Longteng. Because Canon has camera support. Most people who don't know will definitely buy the original brand. Therefore, without two brushes, Longteng is untenable. It is clear that people who use Canon cameras like you will think about this problem.

If you ask me, you don't need a filter to shoot anything with a digital SLR now. Can be in the late PS. This is arbitrary, much better. Add a soft focus effect, and if the effect is not good, you can return it. If the filtering doesn't work, it's over.

What are the common photographic filters and their effects?

If you are a novice photographer of into the pit, I believe you have had doubts about the dazzling array of filter products on the market. What is a protective mirror? What is the function of UV mirror? What's the difference between GND aND nd? When are these filters used? Next, I will share with you the common filters in 1 1 and their use effects!

1. Protective glasses, suitable for all objects, function: anti-fouling, anti-scratch, and play a certain role in moisture.

2.UV filter, suitable for all subjects. Function: UV mirror, also called ultraviolet filter, can effectively filter out ultraviolet rays, improve the definition of photos, provide more realistic and gorgeous pictures, and at the same time play a certain protective role.

3. Polarizer /PL mirror, suitable for all subjects, functions: eliminating specular reflection, darkening the sky, displaying blue sky and white clouds, and reducing shutter speed. There are two specifications in the market: cable offset and circular offset. The former is rarely used.

4.ND medium gray density mirror, suitable for landscape photography, functions: reducing shutter speed, preventing overexposure, suitable for shooting long-exposure works in strong sunlight.

5. Hard-edged GND gray gradient mirror, suitable for: landscape photography, function: reduce the brightness of the sky and balance the exposure of the sky, the ground and the ocean. Generally speaking, the gray gradient mirror with hard edge has obvious dividing line, which is suitable for shooting subjects with obvious horizon.

6. Soft-edged GND gray gradient mirror, suitable for: landscape photography, function: Soft-edged gray gradient mirror is easy to control, and the light and dark gradient line is not obvious, which is suitable for shooting situations where the transition is not very uniform and sharp.

7.RGND reverse gradient mirror, suitable for landscape photography, function: Different from GND gradient gradient filter, the reverse gradient filter is darker in the middle, which can effectively block the highlight objects in the center of the picture and balance the exposure of the upper and lower parts and the middle part.

8. Color filter, suitable for all themes, function: change the color of the picture, but due to the powerful post-production space of digital photos, this filter is rare.

9. Cold tone and warm tone filters, suitable for all subjects, function: correct color expression, or change the photo atmosphere by changing the white balance.

10. Close-up lens, suitable for macro photography, function: shorten the focal length of the lens and enlarge the subject.

1 1. Black-and-white filter is suitable for all subjects. Function: Black-and-white filters are generally divided into four colors: yellow, green, orange and red, which can absorb light with different wavelengths, thus presenting black-and-white photos with different effects. The yellow filter can highlight the contrast of blue shadows and blue sky and white clouds; The green filter can cover the sky and make the outdoor portrait look not pale; Orange filter is suitable for shooting colorful sunrise and sunset; The red filter will deepen the tone of blue sky and sea water and increase the contrast. ;

Ten Common Filters and Their Application Effects

If the camera is the photographer's eye, then the difference between many professional photographers and enthusiasts lies in the difference of a lens. An excellent filter can often make the camera take more beautiful photos. Here are ten commonly used filters I brought and their application effects. I hope you like it!

Ten Common Filters and Their Application Effects

goggles

Suitable for all kinds of photography, functions: dustproof, antifouling, moisture-proof, fingerprint-proof and scratch-proof.

Ultraviolet color filter

Suitable for all kinds of photography, function: UV mirror can weaken the blue tone caused by ultraviolet rays, and for digital cameras, it can also eliminate the interference of ultraviolet rays, which is helpful to improve the definition and color effect. Ordinary quality UV mirrors may sometimes have a negative effect.

Polarizer /PL mirror

Suitable for all kinds of photography, its function is to eliminate specular reflection and increase the contrast and saturation of the picture. At present, there are two specifications on the market, linear offset for film camera and circular offset for SLR.

ND medium gray mirror

Suitable for landscape photography, function: prevent overexposure of the picture, especially when large aperture is forced to use, suitable for long exposure photography.

GND hard surface gray gradient mirror

Suitable for landscape photography, function: balanced exposure, especially suitable for shooting flat horizon with Gao Fancha light difference, such as overexposed sky and underexposed forest.

Gray gradient mirror in soft edge GND

Suitable for landscape photography, its function is the same as that of gray gradient mirror in hard-edge GND balanced exposure, and its effect is uniform transition of light and dark gradient lines, and it is suitable for shooting scenes with uneven horizon such as mountains.

color filter

Application: all themes, functions: change the color of the picture, especially suitable for film photography to add color or modify tone.

Hot and cold regulating filter

Suitable for all kinds of photography, functions: change the white balance correction color, change the color style and atmosphere of photos.

Close-up mirror

Suitable for macro photography, its function is to shorten the focus distance of the lens and realize the magnification of the subject.

Black and white filter

Suitable for all kinds of photography, function: improve the texture of black and white photos, yellow, green, orange and red filters are used to cover different monochromatic colors respectively.

Matters needing attention in the use of filter

Medium gray gradient filter

Change gradient position

The medium gray gradient filter changes from neutral dark gray to transparent, which allows you to balance the large light ratio (for example, when taking photos containing the sky and the ground during the day). When you use the medium gray gradient filter, be sure to check the gradient position, especially after you change the horizontal and vertical shooting mode or angle of the fuselage, otherwise the photos taken may be scrapped.

The gradient is too obvious.

There are two kinds of gradient gray filters: gray gradient filter in hard edge and gray gradient filter in soft edge. Different shooting environments use different kinds. The gray gradient filter with hard edges is mainly used to take landscape photos with the theme of sky and ocean, sky and earth. There is a clear dividing line between the sky and the ocean and the earth in such photos. The gray gradient filter with soft edges is used to shoot mountains or undulating terrain. Two kinds of filters should be used as needed when selecting.

Polarizer

Polarizers are very useful in landscape shooting, which can not only eliminate the reflection of water and green leaves, but also make the blue sky bluer. It is worth noting that the maximum filter effect can only be obtained when the shooting direction is 90 degrees from the lighting direction. When shooting with a wide-angle lens (especially an ultra-wide-angle lens), try not to use a polarizer, otherwise it may appear that the center is bright and the surrounding is dark, or the light and shade are uneven.

Adjust the filter effect again after changing the shooting direction.

The polarizer needs to adjust the filter effect before shooting. If your camera changes from horizontal shooting to vertical shooting, you must readjust the filter effect.

Adjustable reducing mirror

Now many manufacturers have introduced "VariablendFilter", which has the advantage of adjusting the dimming degree and avoiding the trouble of carrying multiple ND filters. However, if the adjustment is excessive, the photos will have black shadows crossing, which will seriously affect the shooting effect and should be highly valued.

Keep the filter clean.

Most filters are installed in front of the lens. If there is dirt, traces and dust on the filter, it will affect the quality of the photo, so it is very important to keep the filter clean.

Don't use inferior filters.

Some people ignore the quality of filters and use cheap and inferior filters. As a result, photos may have low definition, low definition, color cast and unevenness, which will cause fatal damage to photos.

measure

Whether the filter is round or square, it should be used according to the viewing angle and installation size of the lens, and special attention should be paid when using the square filter. When buying, first determine the filter specifications according to the specifications of the lens, and then choose the quality and brand of the filter.
