Another great movie. It's a few years old, so I'm a little late to this party, but I just watched it and loved every second. Definitely watch it if you haven't seen it.
Edit to add a lecture by Philip Steadman, author of 'Vermeer's Camera' and professor at the Bartlett School of Architecture and Graduate Studies. Steadman plays a pivotal role in the development of Tim Jenison's theory about Vermeer. This lecture is nice follow-on to the movie, as he explains his own discoveries about Vermeer's work and also goes over Jenison's technique in detail.
