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.
그리고 여기 이 사진은 정말 흥미롭습니다. 두가지를 보여주죠. 우선 첫째로, 흑백입니다. 물이 너무 맑고 정말 멀리까지 볼 수 있었고 1960년대와 70년대초에는 사진이 느려서 흑백사진을 찍었습니다.
