A photographic close-up is perhaps the purest form of portraiture, creating a confrontation between the viewer and the subject that daily interaction makes impossible, or at least impolite.
I think all photographs lie. They capture such a small amount of a person's personality, if they capture anything.
Like most portrait photographers, I aim to record the instant the subject is not thinking about being photographed, striving to get beyond the practiced facial performance, reaching for something unplanned. While trying to be as objective as possible, I acknowledge that every gesture is still an act of artifice.
