A few weeks ago a fellow blogger asked me how you get the star effects on artificial light in night photos. That person thought it was a stupid question, but I disagree. I think it’s a good question and I think that it’s good to ask about stuff. Without asking questions, there would be no new knowledge.
In my two example shots, you can clearly see the star effect appearing when shooting at a small aperture (I shot at f/22).
Compare the two shot at 25,0 sec at f/22, ISO 100 and 2,0 sec at f/4,5, ISO 100.
The theme for #photo101 today is Double.
