Fireburst filters from Formatt Hitech are a new take on the traditional star filter. Using new manufacturing methods, Formatt Hitech have created filters that produce specular streaks and stars in a variety of points and variety of colors. This filter works great as an in-camera visual effect for cinema, and are also a terrific choice for photographers shooting urban scenes at night. Fireburst filters are available in 2, 4 and 6 point stars. Fireburst filters use the same super slim rotating rings as the Firecrest Circular Polarizers. The filters are threaded onto your lens, and the stars can rotate freely 360 degrees. The filters are also stackable, so you can create any number of combinations of color stars and streaks.
