The Cokin Blue Center Spot filter has a clear center and diffused blue edges. Theses diffused edges will be produce blue colored blur while leaving the center subject sharp. The filter effect is directly influenced by the f-stop and the focal length. A lens shot at f/1.4 will see a greater blurring effect than f/8.0 and a 85mm lens will see more blur than a 28mm. Additionally, a longer focal length lens will visually increase the size of the center spot area because it sees less of the filter area.
