In 1975, Stanley Kubrick famously lit scenes in Barry Lyndon only by candlelight. To do it, he had to use triple-wicked candles for a bright flame, push the only filmstock at the time to 250 ISO and acquire a super-fast T0.7 Zeiss designed for NASA (he had an old Mitchell camera chopped up just to work with this lens). This allowed Kubrick to shoot under a keylight of just three footcandles.

Numerous cameras available today feature a "35mm-sized sensor." How is this defined? They all vary slightly in size, and some are shaped differently so that, when used for HD shooting, the usable size is dramatically reduced. Our clients frequently ask how to compare these different cameras and how sensor size affects field of view and lens coverage. On this topic, words and numbers can be difficult to interpret, so AbelCine decided to produce a graphical chart to better compare areas of coverage.
