So much of photography in South East Asia is spur of the moment. Call it street photography or what you will, but the scenes that play out in front of you show a side of life that, for many of us (myself included), we'll never truly know. You need to always be at your ready in this region of the world, for you never know when you might miss or snap the shot you wish.
As funny as it would be to say that an oxcart just showed up, it sort of did. Yes, you see it coming, but you only have a few seconds to get into position, focus, and shoot. Need to change a setting? Hope you know your equipment.
