X-Ray Film Portraiture with Modified Rembrandt Lighting

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.
