Esther Verhoef said this quote
“ Photography is like stealing.You rob someone of a moment that exposes something essential about their character,their soul if you like.there are people who are very conscious of that,who find that terrifying.The thought that everyone,friend of foe,can get so close to you,look you straight in the eye and judge you without having any control over it or being able to respond.A part of them has become the property of the photographer. ”
