Shutters cracking at a regular shootout in the streets of downtown Hangzhou.

Peripheral vision is a great evolutionary trick, you gaze forward but scan motion to a wider angle, i suppose old desperadoes had mastered this skill. If you are a foreigner walking around Hangzhou you need to be prepared for regular shootout attempts. Usually you get attacked from sideways or behind, the Innocent looking opponent pretends to shoot squirrels in west lake or garbage binσ until you let your guard down and BANG! he got you, another laowai bites the dust. Everything lies in concentration and precise, rapid, hand/eye coordination. As you scan the area for possible hostiles, a group of photography students on the loose, cute couple giggling on the bench, you turn on the camera, holding it facing the ground. Staring far away till you detect motion, SNAP, twist like a professional tango dancer while bringing the camera to eye level, single shot mode, auto focus and crack, shutter down. This gives you the element of surprise and a nice counter collection of natural expressions of people caught red handed. Of course the excitement can die prematurely if people ask permission to take a photo of you which is an equally frequent possibility.
