It is incredibly satisfying how much joy you can give to kids in poorer countries by taking their photo and showing them the result on the camera screen. It’s an icebreaker and a win-win. You get photos of cute kids and the chance to offer something that costs you nothing. They enjoy the novelty of posing and interacting with this magical technology.
Young girls here will often decline your offer of a photo and then chase after you asking for one moments later. It took us a while to figure out why. Then we clicked, they need a chance to put on their headscarves so they are respectably dressed for their portrait.
