As a filmmaker, it is of the utmost importance to have life experience, knowledge of the world around you. How can you have a viewpoint on the world if you know nothing about it. After life has kicked you around a bit you can start you filmmaking education. Here are five great websites that I use frequently to educate myself on various aspects of filmmaking.
Cinephilia and Beyond - http://www.cinephiliabeyond.org - An utterly fantastic website for the true cinephile. Comprehensive, educational, unparalleled. Also, they are donation based so show them some love and throw some dollar bills their way. They often have screenplays from some of the greatest works in film available for free. They dig up other content that you simply would not find otherwise. A favorite piece of mine C&B did on Stanley Kubrick's Barry Lyndon (1975). http://www.cinephiliabeyond.org/stanley-kubricks-barry-lyndon/
Filmmaker IQ - http://filmmakeriq.com - Another website that scours the internet for juicy film related material and puts it all in one nice place. There are also handy lessons on topics from color temperature to the history of aspect ratios. I have spent a lot of time on this site.
Roger Deakins Forum - www.rogerdeakins.com - Not only is Roger Deakins one of the best cinematographers to have ever worked, he is incredibly generous in sharing his knowledge and experience. He answers questions on his own work and the work of others. I have lost myself for hours on end scrolling through the nearly limitless knowledge.
YouTube - www.youtube.com - This one may seem obvious and it is. There is so much information on youtube, one really has to comb through it. Take all opinions with a grain of salt and use a little common sense and you will be able to find valuable tutorials, behind the scenes, reviews, and lectures on YouTube.
Hurlbut Visuals - www.hurlbutvisuals.com - For those interested in camera, grip, or gaffing work this is another great resource. I have not yet taken part of Shane's Inner Circle educational service but I hear good things. Shane is really good about sharing his thoughts on various tools.
