Retro memory day. Here's a link for a post I wrote for Michael Johnston's site over eleven years ago. It's my take on LED lights after just publishing the first photography book about the same. Enjoy?

I love predicting the future. Sometimes it actually works out. 

I'm sure there's still a curmudgeon out there somewhere who is "waiting" for LEDs for photography to be "perfected."
