About Me After working as a research professor in molecular biology, I chose B/W photography as a second career. I use Mamiya medium format cameras and Kodak PX 125 film. Although I print digitally [Epson 2400] onto fine art paper, much of my work deals with silver gelatin printing onto glass, stones, shells, and other three dimensional objects. Both of these printing surfaces [paper vs. 3D] require very different types of photographs.
