Though this timeless image of Ms. Moss from 1996 could have been created with a 2 light setup, Irving shot it using only natural light from a large skylight in his studio.
*Thanks to Nico Silberfaden for suggesting this image.
Camera: Rolleiflex 2.8f twin lens reflex camera with Kodak Tri-X 400 film, set on a tripod 8 feet back from the model. Shot at 1/60, f2.8, ISO 160 (pulled 1.5 stops).
Lighting: A large, overhead skylight lets the graciously-soft northern light pour down at f2.8 toward camera right. This leaves some of Kate in shadow and the right side of the background nicely lit.
Comments: Even approaching 80, Irving was a constant trickster. He would only speak to Kate in a cockney accent and kept referring to himself as Avedon. Tea was served at noon, tequila shots at 2:30, cigarettes continually.
