The Genius of Photography is a 6-hour BBC documentary by the BBC (British TV). It is one of their best, but unless you have a satellite connection, you won’t ever get to see it on American TV.

The videos are hosted on the Chinese version of YouTube, but don’t let the non-English screens scare you. The programs are all in English. Just let your mouse hover over the icons to see the program numbers 1-6 at the end of the line, then click the icon to start the video.

If you’ve got a high-speed connection, this is a great way to blow off a Sunday afternoon.
