In 1979, Kasten started using her Polaroid camera to create instantly-gratifying images of boxes and window-screenings, materials she had used in her earlier camera-less works. She titled these Polaroid photographs Constructs, making dozens of images and compositions through the late 1980s. Kasten’s work is concerned with the interplay of light, color and geometry. Many of the components are staged in positions that rely on gravity to hold them together, lending them a sense of fragility and mystery. Kasten moves in and around these constructions to arrange each tableau, carefully staging each work and controlling the light to create a theatrical space. Construct PC III-A is the second artist proof in a series of photographs depicting Kasten's set design. The series includes 9 unique editions and 3 AP's.
