THINK LIGHT: Has anyone seen my light meter?

This post might make some of my lighting colleagues a little angry, because I'm going to claim that light meters are nearly useless tools. I'm going to claim that the numbers we produce, the foot-candle levels or lux we calculate and measure, the math behind lighting design is all rather pointless. (And before you write...
