What's the difference between UV mirror and starlight mirror of SLR camera?

First of all, they have different functions.

1, UV mirror, also called UV filter, refers to a filter used in digital cameras to protect the lens and improve the image quality.

2. Starlight mirror refers to a camera filter. It can produce diffraction effect of light and form radiation effect, which is mostly used in artistic photography.

Second, the scope of application is different

1, UV mirror is suitable for shooting in seaside, mountains, snowfields and open areas, which can weaken the blue tone brought by ultraviolet rays.

2. The starlight mirror is suitable for shooting night scenes and artistic photography, and the lighting will become colorful. If you shoot a lake or ocean in the moonlight, you will have a sparkling and dreamy visual effect.

Extended data:

First, UV mirror

1, the way to distinguish the quality of UV mirror should be to treat it as a mirror on a black background: what can't be illuminated is a good UV mirror; UV mirrors that can reflect their own shadows are all low-grade. The clearer the shadow, the worse the lens and coating.

2. When purchasing a UV mirror, it should be noted that the lens cannot be color cast. After the camera is equipped with this filter, the wide-angle end, especially the telephoto end, can be clearly focused.

Second, the starlight mirror.

1, the light effect of starlight mirror in use is affected by focal length, aperture and spot. The effect of using telephoto lens is usually better than that of short-focus lens. It is best to use the aperture around F8. If the aperture is too large, it will turn the light into intermittent short lines; If the aperture is too small, the light effect will be worse. The smaller the spot, the brighter it is, and the better the light efficiency.

2. The starlight mirror will produce star flashes with different effects according to the number of thin lines engraved on it and the pattern formed by the thin lines. Common starlight mirrors mainly include: Chinese characters, crosses, rice characters, snowflake mirrors and so on. Special ones are: Victor, Polaris, etc. When shooting jewelry, water, starlight, lighting and other scenes, you can get different types of light.
