A few years ago, I was at the supermarket with my father, on a rainy day, in the south of my country, Chile.
From one moment to another the lights went down, so the main light was natural coming from the front of the supermarket, and a couple of emergency lights that turned on.
I told to my father, quickly! put yourself in the middle of the hall and act as you were from the movie The Mask of Zorro (he was dressing similar), I took my Iphone 6, compose the shot and Boom! This beautiful picture was made.
