There was in a park where I saw this photographer with a potfolio full of pictures he was taken from his customers, It was amazing watch him working. he was considering different location for different type of people, flower backgrounds for young couples, and a fountain for kids etc.. seemed he knews what he was doing he not only didnt mind when I told him I was watching him for an hour and took a couple of shots from him working. but also let me to take some shots from him.
