Although they were incredibly friendly and gregarious, expressing
warm greetings and jovial personas, the second the camera was
turned on them their smiles turned into stoic looks (like early
photographs when the subjects couldn't smile because it took
too long to take the shot, so they would sit with that straight-
mouthed, wooden look on their faces). Then, the instant that the
picture was taken, they were all smiles and laughter again. Though
they seemed genuinely pleased to have their picture taken, nearly
everybody, from old people to little kids, got that same serious look,
so it was tricky to coax a smile.
