Usually, I make sure that my subjects are off-center in the image but this image is an example of “knowing the rules and breaking them”.
My composition works because the two persons in the center are sharp and there is some balancing “weight” in both sides of the worn, blurry glass.
Shot in Aarhus Ø, Denmark.
