And this picture here, it's really interesting, it shows two things: First of all, it's in black and white because the water was so clear and you could see so far, and film was so slow in the 1960s and early 70s, you took pictures in black and white.
Esta foto é moi interesante e amósanos dúas cousas. A primeira é en branco e negro porque a auga era tan clara que podías ver tan lonxe. Ademais, os carretes eran tan lentos nos anos 60 e principios dos 70, que se facían as fotos en branco e negro.
