Subway is a very interesting area. Even if you take subway at the same place at same time everyday, you get to see different people every time, and it never gets bored to peep at the people around me. People read newspaper, play games, listen to music, or just lost in a daydream. Sometimes people beg for money, some people give them money, while others try to ignore them. Millions people with different lifestyles take subway and it never gets bored, because even if most of the people look tired, or maintain expressionless faces, you still can feel the energy of their lives. I think Walker Evans also felt the same way and he wanted to record the energy of the people at that time, and tell the story to the people in the future. Probably that’s why he published his photographs 25 years later.
