I began these studies by photographing groups of trees in a Japanese forest. More recently I photograph piles of books, magazines, and files, to which the title refers. This body of work stems from the study of the perception of multiple vertical lines, both superposed and juxtaposed. The sequential repetition and the continuous movement of the camera create areas of “silence” between the moving lines. The accumulation of “silences” and lines produces a dynamic visual rhythm, altering the perception of the original grid, and creating a visual, musical experience.
