Taking a photograph is an act of possession, a way of making something visible while simultaneously freezing it in place, locking it in time. But what of the mood of the pictures, the loneliness that rolls off them in waves, radiating from Rimbaud’s uncanny, expressionless figure? It seemed to me that they testified not just to a way of life, but also to the experience of feeling different, cut off, incapable of confessing real feelings: imprisoned, in short, as well as liberated by a mask.
