Lens filters with a simple anti-reflection coating are suitable for most shots. UV filters prevent the penetration of ultraviolet radiation which is not visible to the naked eye and also serves as a practical protection of lenses. The advantage is their clearness, therefore there is no noticeable change in light intensity and the photographs of the filter applications are not affected in any way. Applying UV filters is recommended especially when shooting at higher altitudes where UV power is higher.?
