Hi,
Maybe I'm not in the right place but I would like to know if there are good dvd and commercials video tutorials about the direction of photography. I would like to study new methods!!!
Thank you for helping me :-)

Not cheap, but you could check out the Kodak Master's series Cinematography*::*Instructional Videos*::*Books & Videos*::*The ASC Store (http://www.ascmag.com/store/home.php?cat=314&sort=orderby&sort_direction=0&page=2)

I notice that some seem be online Kodak Master Class Series: Lighting Dances with Wolves - YouTube

A good free resource would be from Shane Hurlbut (Hurlbut Visuals (http://www.hurlbutvisuals.com/blog/))
He's a well accomplished DP who shares a lot of how he achieved certain shots in the movie's he's worked on. John Brawley's pretty good too (johnbrawley | ramblings of a cinematographer (http://johnbrawley.wordpress.com/)). He was one of the first guys with a Black Magic Cinema Camera.

The American Society of Cinematographers has some excellent tutorials on their website. Go to ASC: The American Society of Cinematographers (http://www.theasc.com/) and select the "Friends of the ASC" section. You have to be a "Friends" member to access most content. The $100 membership was well worth it to me (you get other benefits besides tutorials). But you should be able to see some sample content for free.
