MUMBAI–Regardless of whether you are a seasoned professional, an avid amateur, or you just got your first camera last week, an excellent way to become a better photographer is to take photo-walks. Walking, of and by itself: exploring a new city, a faraway island, a familiar old trail or a nearby neighborhood is one of life’s great pleasures with or without a camera. But this story is about photo walks and one walk in particular I took with my friend, the inimitable Sebastian John, one hot day over a year ago in Mumbai, India. It was my last long walk in that city I called home for two years and similar to the first long walk I took by myself in Mumbai during the monsoon not long after we arrived. It was not quite as long as that watery hike, because Sebastian and I took our foray into Mumbai’s mad streets in the sweltering days just before the monsoon broke. The heat in that time of year is very nearly hallucinatory. The temperature, combined with the crowds, humidity, smoke and noise, can only be completely appreciated by someone who has been there. Neither a thousand words nor a thousand photos can describe the reality of the streets of Mumbai.
