DE PALMA WANTED SCENE ILLUMINATED BY GUN FLASH
Yesterday, John Huntington at Control Geek relayed a story about how Brian De Palma had wanted a scene entirely illuminated by a gun shot for Carlito's Way. Here is what Huntington wrote about it regarding response time between audio cues and the lighting:
Years ago, when I was working at Production Arts Lighting, we got a call from Brian De Palma's people. De Palma (who I had encountered before on The Untouchables when working for Bran Ferren) was shooting Carlito's Way, and he wanted a scene entirely "illuminated" by the flash of a (blank) gun. They did some tests, and, if I remember correctly, the gun flash wasn't bright enough, and too short to be adequately exposed on the camera. They wanted to take a big 5K fresnel, and have it respond to the sound of the gunshots. We didn't have a lot of time, so we borrowed a pitch-MIDI converter, ran it through Bars and Pipes on an Amiga, and then I wrote some filters there that would generate MIDI messages for a lighting console, that would fire a dimmer which would then light up the 5K. It was very reliable, but with all that early 90's technology, very slow. We did some gun shots, and by the time everything was captured and processed, and the 5K heated up, it was like a second late. It looked pretty cool but was too slow in general to achieve the desired effect.
