I gave out 5 disposable cameras, each in a box with instructions and a logbook. I gave each box (which I call Trust Box) to someone I trust. They each took 3 photos (one that reminds them of the previous person, the one on their surrounding, and one on why they trust the next person) and signed the logbook. Then, they passed on the box to another person they trust, and so on, so that each roll consists of 9 people.
A few weeks later, I was able to retrieve 4 out of 5 Trust Boxes. Each box ended up in a different city: one in Espoo, one in Helsinki, one in Vihti, and one in Tampere. I personally retrieved the boxes myself from the last person from each chain (except the Vihti box -- the last person handed it back to the second-to-last person as they lived closer to me). I got each roll developed and scanned the logbooks from the Trust Boxes. Here are the results.
