Is it true that without a special starburst effect filter one can use a small aperture (f/16 and down) and get that cool starburst-y look to lights in their photos? How come this never works for me? I have a D80 and currently am spending quaility time with my prime lens (50mm 1.4 D) but I have an 18-135mm and a 75-300mm zoom. Christmas came early this year. I would like to get a photo of the lights on our tree and have the lights have that effect. The lights are the normal little ones, but I want to be able to do this on lots of lights, including the sun. Thanks!
