Thanks to reader John D for passing along this video at Filmmaker IQ.
If you are not already familiar with FILMMAKER IQ. (www.filmmakeriq.com) I recommend their 25 minute tutorial on the history and science of camera lenses. While not encyclopedic it is excellent at linking what I read about modern lenses to their historical antecedents. For a YouTube piece it is uncommonly clear and accessible.
DIGLLOYD: definitely worth a watch. See also The Science of Camera Sensors.
While you're at it, this “honest trailer” Star Wars satire is hilarious—and spot on. But wait—Peter Jackson mangled The Lord of the Rings into a video-game-like steaming pile of dung for teenagers, so I’m giving the Golden Turd to Jackson, not Lucas.
