Today I ventured out with my "new" old Nikon D200 which I had converted to a pure infrared camera with a 850nm filter. Only IR light hits the sensor, thus images represent the heat of objects. These were shot this afternoon at Five Rivers Environmental Center in Delmar, NY. The camera is used without need for a red r72 filter to reduce visible light, just expose, compose and shoot after a custom white balance is set. Different but interesting to me. Enjoy, Jeff
