X-Ray Film Portraiture with Modified Rembrandt Lighting

X-Ray Film Portraiture with Modified Rembrandt Lighting

Jim Edwards

This is an example of a portrait made using x-ray film and a modified “Rembrandt” lighting setup. I used a film formerly manufactured and marketed by Kodak, now sold under the name Carestream Half-Speed-Blue (CHSB). Like most x-ray film, CSHB has limited spectral sensitivity and is coated with emulsion on both sides. Care must be taken to avoid scratches when handling, as the emulsion is very soft, especially when wet; twice the emulsion equals twice the opportunity to scratch.

The key light is placed at a 45° angle in front of and above the subject, with a reflector 45° opposite and below. Grids ensure narrow output and sharp falloff. A small background light separates the subject from the background.

About the Featured Photograph(s)

Note

M-mount lenses do not provide aperture information to the camera body, either electronically or mechanically. Therefore, f-stop settings are approximate, and are probably wildly inaccurate. For what it’s worth, I usually shoot with my lenses wide open.
