Henri Cartier-Bresson traveled the world and shot in places such as India, all of Europe, the United States, China, as well as Africa. When he traveled the world, he was able to capture a different slice of life and learn more about the local people he was with. For example when he was shooting in India—he stayed there for around a year and immersed himself into the culture.
Although it is great to shoot street photography in your backyard, it is great to travel as often as you can. Explore different countries and cultures, and it will help inspire your photography and open your eyes.
