I've seen comments on images that say "nice points of light" on a photo with, for example, a street light shot at night.
I'm going to shoot some dark/dawn pictures with limited time for shooting - so not much time for trial and error. Is shutter speed the only parameter which effects these points of light? I assume they get larger with a longer exposure and vice-versa. Does aperture have a major effect on these points, aside from DOF effecting the focus on the light itself? |

Aperture will cerainly affect the shape of the light. With a wide aperture the lights will just be blurry blobs, at very narrow apertures you can get the star effect you might have seen in pictures before.
Think that makes sense, I'll see if I can find some examples... |

Yup, a small aperture is the key. You can also buy a star filter if you want to really exaggerate it.
This was shot over several seconds with a small aperture:

Correct, it's all aperture and how in-focus the light sources are as well. For all practical purposes shutter speed has no effect on the light points, except to whatever degree they may be moving.

| watch out from moving object on slowest shutter speed |
