Mr. Diffley recently wrote an article about “Thinking Black & White” when you shoot photos. This inspired me to find an image that I think works well as B/W, so I found this from the ancient grinding mills at Leine.

If you want to learn more about B/W photography, or just photography in general, I highly recommend Mr. Diffleys blog: http://www.rickdiffleyphotography.com
