My friend Carina, who helped organise our Lares Trek in Peru, saw an article about some photographers who travelled with a polaroid camera giving children in developing countries their first photograph. We thought that would be a fun thing for us, and a nice little present to give to the locals that we came across on our trek.
The kids were delighted to see themselves in a photo for the first time, and eventually the parents and grandparents asked if they could also have a photo of themselves. The team from Apu Andino who travelled with us (porters, a chef, horsemen) also loved having their photos to keep, and some of them spent the first couple of days deciding on what pose they were going to have (horseback? hands on hips? so many options).
