I’ve been a photographer since high school, and an electrical engineer all of my professional life. The two things came together for a while. From 1989 until the middle of 1995, I worked as an IBM Fellow at the Almaden Research Laboratory south of San Jose, CA. My principal area of research for those six years was color management, color processing for digital photography, and color transformations such as gamut mapping. At other times in my career, I did research on speech recognition and speech bandwidth compression, and developed data acquisition and process control computer systems, telephone switching systems, and data communication systems.
There is a list of papers I’ve written and patents I hold related to color here.
I retired in 2000, and for the last 22 years when I’m not serving on NFP boards unrelated to photography, I’ve been spending most of my free time making photographs. I did serve for three years as the President of the Board of Trustees of the Center for Photographic Art in Carmel, CA, but since January of 2012 I’ve been back to trying to make art.
