Roger Deakins is my favourite cinematographer working today. Every time I watch or read an interview with him I'm amazed by his genuine enthusiasm for the craft of photography. You'd think that after 30 years working in the industry he'd be a bit jaded!
Deakins also has a forum he set up where budding filmmakers and photographers can ask him technical questions. Check it out at DeakinsForum. Please don't ask stupid questions, I'm ashamed by the amount of time-wasting questions he gets asked.
Give this guy a fucking Oscar already!
