China - some street photography

I bought the RX100 in Beijing at the beginning of my China tour mid-October 2012, complementing the Leica M9 I had with me. It turned out to be an enlightened decision, as the versatility of the Sony proved to be extremely helpful. I used it most of the time in B/W mode, with contrast and sharpness bumped up to +1. Most shots right out of the box were completely usable, and so the images posted in my gallery (link below) "suffered" very little processing.

I also included a few observations on the B/W modes of the Sony.
Feedback welcome. Thank you.
