The material surfaces represented in my photographs signal generations of past viewers. There are countless people etched into the fabric of these buildings. Their rooms, now animated in a different way from the past, are crowded with visitors clutching guidebooks, city maps, and museum catalogues. These galleries witness the secreted life of artworks, an industry that takes place under constant surveillance and monitoring, without the viewer's knowledge and never in their presence. Outside the museum's visiting hours the art handlers are ghostly figures with ladders that dust, pack, move, vacuum, and hang, reordering the museum space and displays. In navigating the rooms of museums it is not uncommon to find traces of their activity - plaques or empty frames in place of paintings, indicating their transferral to conservation departments, where they are assigned a priority status for restoration, or are packed for loan to another institution. Censored from the public eye are the scores of conservators busily revealing vibrant pigment under centuries of grime, candle smoke, and dust, exposing the layers of previous restorations and mending the damages caused by storage, time, and atmospheric conditions.
