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 most people don't use them. 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. I will install UV protective front lens in the wild or crowded environment, and I will remove all protective lenses in the indoor shed 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.
