The power of water

The mighty Potomac River as witnessed from lookout # 2 at the Great Falls National Park in McLean Virginia.  I also shot this in medium format, square 6x6 format, B+W on a Yashica Mat 124G but I haven't developed that film yet.

Shot with a Nikon D7000 and Sigma 10-20mm lens @ 17mm.  Manual exposure mode, F18, 20 seconds shutter speed, ISO 100, Spot metering, tripod mounted and shutter triggered with Nikon infrared remote.   B+W brand ND110 (10 stop) neautral density filter screwed on the front of the lens after manual focusing in order to give the long exposure time.  Processed in Lightroom 4 and Photoshop CS5.
