I live on the Northern California Peninsula and work both as an Electro-Optics Applied Physicist and Developer of 3D Modeling and Simulation Algorithms for Science and Engineering.
A salute to the people who help me get down the road.
I lived in Southeast Asia when the food, clothing, and housing were free.
I'm authoring the world famous Photographic Lens Performance blog.
Photo restoration is a fun avocation that brings together many skills from my professional experiences.

For Measurement Of Geometric Distortion To 10nm Levels, It's Mandatory To Know The Exact Shape of Your System's Point Spread Function Across The Entire Field.
