This is a circular polarizing filter, also known as circular polarizer. Polarizing filters are perfect for landscape photography and removing reflections. As shown in demonstration photos. A warm tone version was used which has made the picture look more like a summer's day. A polarizing filter used on water and windows kills reflections allowing you to see below the water surface and behind the windows. Another usage is to reduce glare on non-metallic surface such as wood and plastic signs.
