What is a UV Filter?

A UV filter, also known as a UV absorber, is a type of filter used in photography and other imaging applications to reduce the amount of ultraviolet (UV) light that passes through the lens. The purpose of a UV filter is to protect the lens from dust, moisture, scratches, and other damage. Additionally, UV filters can also reduce the bluish tint that can sometimes be present in photographs taken in bright sunlight.

UV filters work by blocking out the UV light that is present in sunlight. This light is invisible to the human eye, but it can cause a bluish tint to appear in photographs taken in bright sunlight. By blocking out this light, the photograph will appear more true to life. Additionally, UV filters can also help to reduce the amount of haze that can be present in photographs taken in high altitude or in areas with a lot of air pollution.

UV filters also serve another important purpose: they protect the lens from dust, moisture, scratches, and other damage. This is especially important for lenses that are used in a variety of environments, such as outdoor photography. By using a UV filter, you can ensure that your lens will remain in good condition and will be able to take clear, sharp photographs for many years to come.

In conclusion, a UV filter is an essential tool for any photographer. It helps to protect the lens from dust, moisture, scratches, and other damage, as well as reducing the bluish tint that can sometimes be present in photographs taken in bright sunlight. If you are a serious photographer, then a UV filter is an essential part of your equipment.
