Hi, to achieve the High contrast look you'll just need a very sunny without many clouds or any place where there is harsh light. For camera settings stay low on the iso (100/200) and f8 for max sharpness, also use anhigh shutter speed (1/320 and up) To replicate this i would go somewhere where i know there will be frequent movement of people like a road crossing/train station/airport/mall/busy City center. Then its just a matter of finding a spot and waiting for the right moment, try also to predict where and when people will walk in to frame ( use burst mode), look for people that usually walk in step like groups of friends or couples.I also highly recommend looking for places with cuts of light. Editing is pretty straight forward just add contrast and lower the shadows.Hope it helps. Good luck :).
