One interesting thing that we can see at night photography is the star effects of the street lights. If we have a star filter, it is very easy to do that. Just plug the star filter and capture images as usual. Automatic light bulb on the street will give you star effect.
In this tutorial we will learn how to produce star effects without using the star filter. Actually it is very easy to do.
What we need to do is to set the camera aperture as small as possible (f/large number). The principle is similar to the way our eyes work, if we try to narrow our eyes and look to the light, would have seen the light produced a star effect. By setting the camera with small aperture, it will have an impact on a slow shutter speed to produce a balanced exposure, for that we will need help from a tripod to keep the images not blur.

Below is a lighting candle that I captured with 8 Stars Filter plugged on my lens. The ISO Speed is 200 and f/4.5 on my Nikon D70s.
Let's see the image below. I took it without star filter, just aperture setting on f/29 and exposure time 15 sec.
You can see the star effect from the candle's light.
It's very easy!
This is another image that I capture with my Nikon D200 without a star filter. Just set the aperture on f/16, ISO Speed 100 and exposure time 30 sec. Look! I also got the motion blur from the light of the car.
Okay. It's time for you to try it. Easy way to get a nice shoot!
