THE POST-PRODUCTION: digital backlot

sin city is one of the first films (along with sky captain and the world of tomorrow, casshern, etc) to be shot primarily on a digital backlot. a hd camera was used to shoot footage of the actors working in front of a green screen that allowed an artifical background (and some major foreground elements) to be added in later during post-production (though some hand-constructed sets were built for a few of the scenes). with the use of a sony hdc-950 high-definition camera and green screen together made sin city one of the few fully digital, live-action motion pictures. the whole movie was shot in color against a green screen and then was converted to a high-quality black and white film. as noticeable in the film, colorizaion was used on certain objects in a scene for emphasis. the film was color-corrected digitally and then was treated for heightened contrast (film-noir style tradition) to separate the whites and blacks more clearly.
