The modus-operandi was simple: wander around, pick some good one, negotiate (sometimes with the help of an interpreter - phd student, local project manager, etc.) and shoot. While the picture was self-developing, write “AlaReLa project 2014” on it and make a scene of drying it and all… give it to the model and try to escape the hords of people wanting to get one as well. Repeat later, farther… I tried to get a wide variety of models: kids, teenagers, workers, old folks, both genders. I then asked them to be pictured with their instant-photo by joking that my boss wouldn't believe me that I worked if he had no proof! There is nothing better than the common enemy of “the big boss” to make friends…
