The 52mm P Series Starter Kit from Cokin features a P197 Sunset Filter, which is designed to simulate a sunset at any time of the day or to further enhance an existing sunset by adding more color when you are photographing landscapes. The colors are a mixture of a graduated orange with reds to give the appearance of a sunset. At the top of the filter the colors are denser; graduating to softer colors towards the bottom of the filter.
The filter is made of a CR39 resin, which is optically clearer than the poly-carbonate resin. The kit also includes a P size filter holder and a 52mm adapter ring, which is compatible with most lenses of the same diameter.
