    i took this picture just this night and loved it, i left the shutter open for 30 seconds to let as much light in as possible, it was almost pitch black out. so i could photograph the tower, and the street light changed over that time and i guess made a starburst effect with the lighting,
    i had no idea i could get such results without a starburst filter, unless it's my UV filter playing tricks on me
    anyway, i thought i would share my epiphany :p

    If I remember right, a small aperture (high F stop number) is what creates the star effect with lights.

    Nice shot.

    Yup, about any SLR with a numerically large aperture can do this effect.

    It can also be created using starburst filters on the lens and in photoshop.

    It's diffraction at the aperture blades: the more blades the more points.

    Best,

    That's an awesome shot! I did that with the moon- hopefully you'll be able to see the pic because I sent it to the January contest. :)
