During our trip to Peru and Bolivia, the bus driver stopped along the road to allow us to take in the view of the city of La Paz, Bolivia. I was amazed by the size of the mountain in the background and the city's smallness—what a contrast of altitude, colours, and shape! To capture this shot, I used a 146 mm focal length (35 mm equivalent).

I have done this trip with a group of 8 people on a private tour. I was the sole photographer. On the first occasion, when I saw a beautiful landscape, the lighting was perfect. I asked the bus driver to stop. He answered me politely, "Sir, you are not on a photo tour." I saw so many beautiful landscapes in South America that, to truly enjoy a photographer's passion, a photo tour is a must.
