If you ask most camera owners why they use the filter on their camera lens? Most of them will tell you that this filter is for lens protection. Although filters protect the front glass surface of the lens from dust, moisture, and fingerprints, the main function of photographic filters is to enhance the quality of the camera shot.

Of course, we have to say that This increase in final image quality depends entirely on the type of filter you are using. In fact, some filters have a small effect on the quality of the final image and others greatly increase the quality of the final image.

Due to the existence of different filters in the market and with different applications, in this educational article We plan to review the types of photo filters and answer any questions you may have when purchasing the right filter for you. So join us.

Do filters have only a few basic models or do you have to make too many filters?

The simplest filters available that you might hear their names. You may have eaten UV-reducing filter, Skylight filter, and lens protection filters. Protective filters sold in the market, according to their manufacturer, may only be glass filters that have a light-reflecting coating. Of course, we must say that there are protective filters on the market that, in addition to protecting the lens, also have a UV filter. Of course, in general, the UV filter provided by protective filters is very basic.

In order to keep the windshield in front of your lens clean and healthy, it is enough to choose a protective filter from the available models for your camera. Is. But if you are looking for a filter that not only protects the lens, but also enhances the quality of your photos and videos, you should get a UV filter or Skylight filter for your camera instead of buying a protective filter.

UV filters that Also known as Haze filters, they are designed to remove moisture and other airborne contaminants when shooting in the sky. Undoubtedly, the presence of any of these things in the sky during photography reduces the quality of the final image.

UV filters on the market have different intensities, each of which must be in different conditions, such as near Large lakes, high-altitude environments, snowy conditions or other similar conditions that increase the intensity of the sun's ultraviolet light in the environment should be used.

Depending on the type of UV filter used, the amount of power It, as well as the photographic environment, may be suitable for the purchased filter, and ultimately the final photo will be captured in a higher quality. Of course, if the power of the UV filter purchased for the shooting environment is high, the final photo may take on a warm, yellowish state, which photographers are forced to use half-stop exposure compensation to prevent this from happening.

In addition to UV filters, there are other filters called skylights that can even replace UV filters. These filters have two different powers, which are Skylight 1A and Skylight 1B. Unlike UV filters, which cause photos taken to turn yellow, Skylight filters cause the final image to turn magenta. Natural skin color, or photography with analog cameras is more appropriate. Typically, photos taken with negative film tend to be blue, and the use of a skylight filter when shooting with an analog camera balances this blue tendency with the magenta created by using the filter./p>

It does not matter what type of Sky filter you use and with what power. Skylight filters have no effect on the exposure of the camera and, like UV filters, only remove dust from the sky when shooting.

We should also mention that these filters protect your lens from dust. They also protect against dust, moisture and fingerprints. The interesting thing about lens care is that if all lens contaminants such as dust, moisture and fingerprints are not quickly removed from the camera lens, they can damage the lens cover in the long run.

Why does one UV filter cost several times as much as another UV filter? With a very similar appearance, they have a very large price difference. At this point you may be wondering what is the difference between these filters? To answer this question, the first difference between the two filters is the difference in the quality of the glass used to make them.

You may be wondering how much can two different glasses do? They differ from each other, but you should know that the difference in quality of the type of glass used to make the filter manifests itself in the quality of the final image.

In fact, the main difference between a quality glass and a normal glass The difference in their chemical composition is related to the method of manufacture and even the place of manufacture of those glasses. Even other parameters, such as the thickness of the glass, indicate that thinner glass is better, and the type of coating to minimize optical errors and maintain color accuracy and contrast levels also affect the quality of a filter.

It is important to note here that using a standard filter or an expensive filter on the camera kit lens may not make much difference to the final image quality. But when you use these filters in professional and expensive lenses, the difference between the quality of the photos taken will be quite obvious.

    For example, if you look at color filters and polarizing filters, you will find that depending on the type of filter, a layer of colored film or polarizing material is placed between the layers of glass that make up the filter. In expensive filters, this layer of paint or polarizing material is attached to the layers of glass. Doing so will remove the air layer or other irregularities that can adversely affect the optical quality of the filter.

    Another difference between conventional filters and expensive filters is the type of retaining rings. These retaining rings in inexpensive filters are made of materials such as aluminum or other soft metals. Deform on the ring. In expensive filters, these rings are made of metals such as brass, which makes their retaining ring have good resistance, and even if you hit your lens, the filter does not get stuck to the lens and can be easily removed from the lens. p>

    The final point in choosing a filter is that if you use an expensive lens, it is better not to waste your investment to buy an expensive lens by not using cheap filters.

    We must also say that there are other types of filters that have a higher price compared to normal filters due to their resistance to different weather conditions. If your favorite style of photography involves traveling or shooting in difficult weather conditions, it is best to choose a filter that is resistant to harsh weather conditions.

    In addition to UV and Skylight filters, what are the filters? Are they suitable for everyday photography?

    If you take more pictures of landscapes while shooting, or your style of photography is such that you have to go out for a photo shoot, we recommend that you Provide a polarizing filter. The use of these filters causes the clouds in the sky to show themselves beautifully in front of the sky, which is recorded in a dark color.

    The use of these filters also increases the richness of colors and It also removes radiation and light reflections from water surfaces, glass and other glossy surfaces.

    Polarizing filters close during installation on the second ring in front of the lens. As a result, you can manually rotate the filter when shooting and viewing the camera through the viewfinder, thereby determining the appropriate power for the polarizing filter.

    Despite the various advantages, one of the points The downside of a polarizing filter is that if you use these filters, the light of the image will be reduced by about 3 stops. Of course, we have to say that the effect of this filter on the final photo is such that you can not use photo editing software such as Photoshop to edit your photo and look like a photo taken with a polarizing filter from the beginning.

    Also linear polarizing filters for use. Suitable for lenses with manual focus system. In fact, circular polarizing filters can be used on lenses with autofocus and manual focus, and the final image quality will be the same in both cases.

    There are also certain types of these ND filters on the market. Like polarizing filters, you can rotate them to change their intensity when shooting and adjust to a certain level.

    What is the difference between ND filters and Graduated ND filters?

    If you look closely at ND filters, you will notice that these filters have the same density throughout. But if you look closely at a Graduated ND filter, you will see that one side of the filter is completely transparent, and as you move to the other, the density of the filter gradually increases.

    Graduated ND filters are suitable for certain times. The scene you are photographing has drastic changes of exposure in its opposite parts, ie up and down or left and right. In fact, these filters try to make the light of such scenes uniform.

    In addition to dimming filters, there are other color filters that can be used for Adding specific colors to the final photo along with darkening the background or foreground of the photo.

    Is it necessary to provide warm and cool color filters for photography?

    As the name implies. Filters It is clear that the preparation of hot filters adds yellow and the preparation of cold filters adds blue to the final image. While these colors can be added to the final photo when editing photos taken with software such as Photoshop, many photographers, especially those shooting with negative videos, prefer to use these filters when shooting.

    Of course, sometimes Warm filters can also be used to enhance photos taken on cloudy or rainy days. As we said, in addition to hot filters, there are cold filters that can be used to reduce the color temperature of the final photo in some cases.

    It is important to know that when using hot, cold or other filters If you are using a color in your digital camera, it is best to adjust the white balance settings to be close to the natural color of the environment. For example, set white-style settings to daylight, cloud, tungsten, fluorescent, or other options depending on the ambient light.

    In fact, you should set the white-style settings to Do not set to auto mode, as the camera will try to correct the colors you are looking for using the filter and display the colors as best as possible. In fact, if you set the white mode to auto mode, the final photo will be different in color from what you saw in the viewfinder.
