Allow me to introduce a bit of conventional education into your day. Mark Vargo provides us with a well-edited trip through the history of light sources in Cinema. This is a little lengthy, but I assure you, you'll be glad you watched it. While the tone is very PSB-esque, the content is great. The video provides great insight into how we got to where we are today. It certainly doesn't hurt to go into the new year with one more thing you've learned. Take it all in and enjoy.
