This is an image I took along the Grand Canal in front of Basilica di Santa Maria della Salute. I was taking pictures like a madman at the time but the conditions for photography were not good. Normally, to take pictures at night you need a tripod and a stationary subject.
In this case, I was in a moving gondola and my subject was moving also. To get this I used an aperture of f1.8 and an ISO of 8000. That's extreme but with a few adjustments in post-production, it's a winner. So much for the old rules.
Because I don't know what all the rules are I do things that another photographer might not. I make a lot of mistakes, but I also get some good shots under difficult situations. The tech is so good now you may as well push it and see what happens. One day we'll have sensors in our eyes and cameras will be obsolete. But until then, it's fun to keep breaking the rules and trying new things.
