A look through the window

A look into a side room through a closed door at the Eastern State Penitentiary, built in 1829.  At some point there must have been a sign on the door because there were still tape remnants stuck to the glass.  Shot on a very cold President's Day afternoon, 2-18-2013.  For more information on visiting the historic prison see their web site at: EasternState.org.
 
Shot with the Nikon D7000 and Sigma 10-20mm lens @ 16mm.  Aperture priority mode F11, ISO 200, spot metering, exposure bracketed for one set of three frames with 2 stop variance (-2, 0, +2 EV range).  Camera was tripod mounted and shutter triggered with Nikon infrared remote.  Tone map post processing of the exposure brackets done with NIK HDR Efex Pro 2.  Further processing done in Photoshop CS5.
