It is essential to always carry a camera in order to profit from the rare opportunities and coincidences offered in everyday life. This is now getting easier with the miniaturization of cameras and the popularity of intelligent cellular phones.
The street photography above, that I took in London in 2015, offers a good example of an ephemeral subject that a street photographer should not miss.
A policeman posted in front of an embassy is having a chat with a citizen. This normally innocuous situation is suddenly rendered more interesting because of the difference in size and the relax attitude between both interlocutors. They have almost the same posture and are dressed in the same colors. Here, the skin color is not the dominating subject although it certainly adds some interest.
