I spent three weeks in Thailand last November, and of the six-hundred-and-something photos I took the ones that pleased me the most were the grab shots, taken with no time for setup and that were gone a split second later.
This one's my favourite. I was diddling around taking some pictures of some crabs skittering around in the mud at low tide. Then I turned around and found my guide/interpreter chatting with this interesting woman. I grabbed the shot and moved on...I'm still self-conscious about photographing people I don't know when they're not expecting it.
Anyway, I offer it for your consideration and comments. It's a severe crop of the original image, which contained a lot of clutter (I didn't take the time to zoom in).
Regards,
Ken
