Here are few more images from my walk along the canal a couple of weeks ago. I took my Sigma DP1 with me and shot for HDR, quite difficult handheld.
Grand Union Canal Company
Old Rundown Mill Factory
This old factory is quite difficult to photograph as the sun is directly behind it, but the HDR helped.
This old factory building is used as a recording studio and as the name implies it stands next to lock 42 on the canal. I really like the architectural panel above the doorway.
