Steam vortices rising from the Delaware River at Stockton, NY. This was a very cold morning (5-6 degrees F), late January 2014. The steam can be seen frozen in the trees. Taken with a Ricoh GR (28mm equivalent focal length), converted to B&W in Lightroom 5, slight sharpening and contrast enhancements. ISO 400, F/8, 1/4000 shutter speed.
