End of the dive.
I took this picture at the end of our dive. I was waiting under the boat and looked up to see if it was already safe to step up the ladder. Another diver of the team was just climbing up to get in the boat. I saw the sunrays spreading their light and thought this is the perfect moment for a picture.
My favorite photographer is Henri Cartier-Bresson. He was a real master in candid camera and street photography. If you hear the term "decisive moment", he's the one who defined it. Cartier-Bresson was also one of the founders of the famous Magnum Photos Agency.
