While in the Middle East, one had to be aware that a few individuals from the village would not want to be photographed. There was a belief that an image has the ability to steal one's soul. Of course many educated youth turned pleasingly theatrical when a camera appeared. Still, an image is something special.
On the recent trip to Europe, we got to see many of the first individuals who saved their images. Hundreds of years before photography only the rich or powerful could see themselves represented in pigment. They can still be seen today. We don't get too much of a glimpse into their souls, but we definitely get an idea of hair style choice and nose size.
Anyway, it's more than a trip down memory lane, modern imaging allows us to capture moments that will live beyond our own frail bodies. I find that very interesting.
