To do it you;
- Cut a circle the size of your camera lensÂ and cut out a shape you like.
- WeÂ tried it on a 55-80 mm lens. We are not sure it would work on another one.
- Put it on your lens.
- Point it at some lights and get them out of focus.Â If you did not make the hole too small the lights will look the shape you cut out!
