One of my favorite types of books is those where the photographer visits the same spot a century after the original photograph was taken, such as John Fielder’s Colorado visits in 2000 to where William Henry Jackson had stood in 1879. In the same spirit, I created a movie in a West Virginia hardwood forest from the same point six months apart to document seasonal change. It is fascinating to compare the differences over a century, or a season, or just a day, as I did on the Maine coast.
