If you guys have not seen this, i think every DSLR filmaker should. Vincent Laforet is a god among mortals and this is some of his amazing work. Shot on a Canon 1d MarkIV and with nothing but the light of the streets.
haha...Vincent is well beyond shooting photo's. He's a very strong cinematographer at this point and has been for awhile. I have a feeling this may be a repost. You should check out his site/blog to see how much work he has done.
