Introducing something small and intimate into the viewing area of a public sculpture, Steuart Bremner is doing what he calls 'Live Photoshop'. The resulting photographs suggest questions about scale and preciousness. The technique for including the object, is not usually hidden so that it's clear that the viewer should questions what's real.

The photos here include interventions with land art made by Robert Smithson and Michael Hizer, and sculptures by Claes Oldenburg, Pablo Picasso and with museums like the MCA Denver and the Museum of Contemporary Art in Chicago.

Similarly, Rock Monuments is a series of work that elevates a small object to a precious position where it interacts with a broader landscape.
