Sometime in the early 1990’s I ran a cross a flyer that mentioned “Model Shoots” or something and I was curious so I attended one.  This might have been at the Gardena City Hall, and there were about twenty “models” -- mostly young women from 16 to 25 -- posing for what looked to be very amateur photographers.  It went from titillating to creepy pretty fast.  I kept looking for signs of disgust from the models, but they seemed to be having a decent time.  At the PG rated shoots I think they just showed up, often with their mothers, to compete for trophies and get free prints, but at the shoots with nudity they were clearly paid.  And these women were older and seemed like strippers, though they didn’t dance or actually ask for tips or anything.
