There are many subjects that will get people mad on the internet, but in cinephile circles, the reddest flag is aspect ratio. Ever since the bad old practice of pan and scan was abandoned, DVD and Blu-Ray releases have tried to echo the widescreen aspect ratio that a film was released in, but that's often very hard to get right. Most recently, the Blu-Ray reissue of Stanley Kubrick's Barry Lyndon resulted in prolonged arguing and triumphant research. How did things get so confused? Filmmaker John Hess is here to explain, with an extensive and excellent history of aspect ratios.
Masters of Cinema is a film blog 'for discerning cineastes the world over,' with news on directors, films, dvd releases, aspect ratio controversies, and many links to director tribute sites. They also have sites dedicated to Robert Bresson, Carl Dreyer, Ozu Yasujiro, and Andrei Tarkovsky. (The last two previously posted by hama7 and I, but it's nice to see everything together)
