Their brilliance lies largely in their artifice, and the illusionism of color and scale aligns them with painting as much as sculpture. The photograph pieces often stand apart from their natural surroundings which become a form of background or context. Characterized in this way by having distinct boundaries, they work ideally as framed photographs on the wall of a gallery. Without exaggerating the distinctions between the types of project in this respect, it can be said that surprise, illusion, and other characteristics that make the small works immediately arresting and separate from their surroundings are less prominent in the large projects, where continuity with the environment is a part of their identity, and their character is partly defined by the modest, sometimes minimal, difference between the sculpture and the adjacent landscape.4 Although distinct objects, the environmental works differ from the small ones in that they cannot be removed from the landscape. To photograph one and place it on the wall of a gallery would simply be to document what the artist had done, rather than exhibit a work of art: the life of the large works is there in the landscape and nowhere else.
