Peter Jackson will shoot the Hobbit films in 3D on RED (digital) cameras. More good news for the industry in general as well as low-budget filmmakers since film (and related processing) is probably the single most costly element for most productions.
The RED camera has already been used to shoot several high-profile movies, including 'Che' and 'The Informant!' -- Steven Soderbergh was one of the first Hollywood directors to embrace digital cinematography. 'District 9' was shot primarily on RED cameras. Michael Mann, I believe, shoots mostly digital now. 'Collateral' certainly has the look, as does 'Miami Vice' (memory fails me though).
Early movies shot digitally had a kind of gritty, grainy quality. I think that problem has been solved and imagery from the latest REDs is silky smooth, tighter than film. In low light, film can't compete with digital sensors. A lot of stuff is being shot at night on digital cameras without the use of huge banks of lights, generators, etc., which is basically impossible on film. I think they did that for 'Skyline'.
Small film crews can rent digital cameras, saving thousands in film-related costs. Between that and internet distribution, we might see a revival in the low-budget indie film scene, giving the new Cassavetes and Woody Allens their chance to change the world.
RED has been threatening to come out with a consumer still/video DSLR. I'm hoping. Will give Canon and Nikon something to worry about. We could use the competition.
