People are the toughest subject to photograph.
Every time you take a stranger’s picture you actually invade, to a certain extent, his or her privacy.
I ask permission to take a picture whenever possible. In many cases they look at me without saying a word, and I need to gently go away.
In some cases, I am lucky to photograph those I wanted to. It is the interesting face, expression, or gesture that impressed me. Some images may impress you too.
