'Capture'. Dryden Goodwin.
I'm a big fan of Dryden Goodwin's work, his series of images involving strangers are particularly interesting. He aims to break the boundaries that are built between strangers, in a way that would seem invasive. It's normal to pass hundreds of strangers with out motivation to get to know them. It's acceptable for many reasons, fear of the unknown could be a factor.
Making marks on the face in white emphasizes the contors and shape. This could be seen as an act of affection, highlighting our individualism. But I think if I placed myself in the position of the subject I might feel my privacy being invaded.
