I spent the Spring of 2006 experimenting with infrared photography. The Nikon D70’s hot mirror filter was inefficient enough to allow for reasonable shutter speeds under sunlight. In this case, a bit more than 1 second at f/8 and ISO 200. It was a breezy day, and the long shutter speed allowed the branches to feather out, while the trunk stayed sharp. As usual with D70 infrared photos, there is plenty of tonal adjustment to increase the contrast.
