I worked on a print over the weekend of this picture as well. A photograph I took back in 1972 of what I believe is the Crown Zellerbach factory in Oregon City. The thing was huge and built right on the shores of the Willamette. It's like some modern version of Mordor. I also experimented with cutting a mask so I could print the sky with some additional exposure and with a higher contrast filter to darken it a bit more. I wonder what is there now?
