Is the UV mirror a filter?

UV mirror belongs to ultraviolet filter. Because it is cheaper, people generally use it as a protective mirror, but it will weaken the atmospheric perspective effect. Sometimes it is necessary to take off films with dim vision. Another point is that cheap UV mirrors are generally not coated well, or there is no coating, and glare is very likely to appear on the screen when shooting in reverse light. It is a wise choice to wear a hood when shooting, and try to avoid the lens facing the sun directly. On the one hand, glare can be avoided, on the other hand, CCD or shutter curtain can be protected from being damaged. UV mirror can also be replaced by sky mirror. The first question is clear. UV mirror is not a filter to shoot the sun. Never use your camera to point directly at the sun. Don't point the camera directly at the sun when shooting during the day. If you need to shoot a scene with strong backlight, you can wait until the sun goes down, or turn your back to the sun and turn on the flash to solve it! This has little to do with the season. It is ok to shoot with a smaller aperture when the sun is dark in the morning and evening, but never point the camera directly at the sun at noon or in strong sunlight.
