What is an ultraviolet filter?

For use in a photo, an ultraviolet filter is usually a clean filter connection that screws up at the end of the camera lens. They are used to filter out ultraviolet rays that can cause outdoor photos to look foggy and bluish. Most removable lenses of removable cameras can receive UV filter, including video, digital and film cameras. These filters are not generally for use on point and shoot cameras with fixed lenses. In internal situations, this is not so much a problem, but in outdoor photography, UV light can result in a picture that is not fresh and has a little indigo shade. To prevent this, the ultraviolet filter can be used to absorb ultraviolet rays, add cleanliness and reduce foreign shades. Still, ultraviolet filters can be useful for film and digital cameras. In digital photography, the ultraviolet filter also helps reduce the color problem known as the purple fringe-violet ghost line around the photographicabout the subject.

The typical ultraviolet filter is clean and filters UV-B and UV-C rays shorter wavelengths, almost completely transparent to visible light. Therefore, these filters can be left for almost any shot. Ultraviolet filters offer another advantage of lens protection; If the lens is dropped, the filter absorbs damage rather than the lens. It also helps keep the lens clean and without scratches before frequent cleaning; In general, it is much cheaper to replace a scratched ultraviolet filter than a scratched camera lens.

Some stronger ultraviolet filters that filter heavier turbidity or higher levels of ultraviolet can cut off some visible light in the purple part of the color spectrum, causing the stress effect on photos. Yet they do even better work in preventing the purple edge. As a result, the use of this strong ultraviolet filter may require some compensationColors in photographing a photo or during photo processing.

There is some controversy about the use of ultraviolet filters. On the plus side, it helps filter ultraviolet rays that cause wrap and bluish shades, and offers added lens protection. Opponents say that the added filters can cause flares, which worsens the quality of the photo. Another potential disadvantage is that the use of UV filter reduces the use of light lenses. This is because not all filters have fibers into which other accessories are screwed, and adding the bonnet to the lens to the filter can lead to problems with color and saturation of colors.
