Infrared Portrait, photo by Harold Davis. View this image larger.

As opposed to Dream and Christianna, which were taken at a high ISO using mostly ambient light, this infrared portrait was lit with (mostly) direct studio strobes for a fairly normal studio exposure (1/160 of a second at f/8 and ISO 200).

The infrared capture makes Christianna’s skin look almost like ivory—very different than a photo made with normal sensitivity to light.
