The Hama Skylight filter has a number of benefits. The filter protects the lens from scratches, dust & finger-marks which can be hard to clean & impair the quality of a photo. The filter can also help to make the cleaning of your camera a much easier task. A lot of camera lenses are curved & recessed, the flat surface of the filter means that maintaining your cameras cleanliness is a more straightforward task. The filter is robust, solid & fits tightly on the lens. In addition the Skylight filter can improve the quality of your photos. The filter acts as a colour corrector designed to correct the slight blue cast that results from shooting pictures under an open blue sky. This is especially useful when shooting in the snow on or a beach. The filter provides a hint of warming to counterbalance the excessive blueness of naturally bright light. The filter also produces sharp & clear photos of objects that are farther away. As an extra bonus the Skylight filter also absorbs ultraviolet rays which often make photos appear pale & grey; with the Skylight filter photos are richer in contrast, without effecting visible light balance.
