It’s not a good photograph without good composition. Originally I’m an aeronautical engineer. Why do airplanes fly? Because there is balance.
A good photograph speaks to many different people for different reasons. It depends on what people have been through and how they react.
The other sign of good photography for me is to ask, “What am I going to remember?” It happens very, very rarely that you see something that you can’t forget, and this is the good photograph.
