I look for the things that create emotion, the guy grabbing the crouch of a statue, the lonely smoker sat in the alley... these things cannot be planned, sometimes you can take your time to compose your shot, sometimes you have to shoot with what you have got and compose on the run, I still find those fleeting moments the hardest to take trusting my settings and not fussing with the camera... most of all street photography should be addictive and fun!
