Dick Lyon

Hi, I'm Dick Lyon. I am a research engineer in Silicon Valley, California. I've been contributing to Wikipedia since May, 2005.

Some of my work outside Wikipedia is linked on my techie home page

Contributions to the Wikipedia[edit]

My contributions are mostly related to photography, photometry, color, electronics, and signal processing.

Here I collect most of the pictures I've uploaded, including my own, public domain works, and works licensed by a few friends.
