I like the look of night time shots, so I do it often. I've noticed that when I use the Digital Rebel I get a star effect on the lights without using a star filter. It happens everytime. I think it's pretty cool and I was wondering if anyone else has had the same experience and if you know why this happens.
Here's an example:
On the other hand, here's one taken with my Kodak DX4900

| I usually get it when I use a longer exposure. |

I think it's the product of using a very small aperature, like f/16 and smaller.
Typically, the P&S cameras don't go that small.
I have a few examples:
 f/14 + 30 secs  f/16 + 30 secs
but:
 is only f/4.6 and 1/6 sec

mariomel is correct, the smaller the paerture (larger number) the more pronounced the effect. You can usually see them easily from f/8 on up. The number of points on the star is related to the shape of the aperture, which in turn depends on the shape and number of aperture blades.
