![Kubrick was “determined not to reproduce the set-bound, artificially lit look of other costume dramas from that time.” After “tinker[ing] with different combinations of lenses and film stock,” the production got hold of three “super-fast 50mm” f/0.70 lenses “developed by Zeiss for use by NASA in the Apollo moon landings,” which Kubrick had discovered in his search for low-light solutions. These super-fast lenses “with their huge aperture [the film actually features the largest lens aperture in film history] and fixed focal length” were problematic to mount, but allowed Kubrick and Alcott to shoot scenes lit with actual candles to an average lighting volume of only three candlepower, “recreating the huddle and glow of a pre-electrical age.”](http://4.media.tumblr.com/dnu59N59rqfxw44tbjWiTmf6o1_500.jpg)
