I think I could compile enough images of mill windows and doors to fill a couple of books.

This set of staggered, narrow windows climbing a corner of the building at Malden Mills was begging for a different treatment.  I shot it when I had the Nikon 24mm PC-E lens a couple of weeks ago. I liked the combination of the angled composition and the effect of the lens tilt.

Im curious as to what the building was used for. My guess is it was a textile store house originally. Small windows limited the light entering the building and minimized the fading of the dyes on the fabric.
