Slumdog Technology Convergence

"I had to find a camera set up that would be ergonomic enough for me to throw myself around the slums chasing the children whilst, at the same time, withhold as much detail in the shadows and highlights” says Anthony Dod Mantle. Our producer, Chris Colson, had hoped for Danny and Anthony to repeat the efforts on Mini-DV”. This was all well and good, except for the monumental difference between shooting multi camera fiction on sets where I could light, sometimes quite heavily. We needed a digital camera with enough latitude to hold highlights and something very small so we could enter the children’s world at their level. “Slumdog Millionaire” needed a completely different tactical approach.”
They found the right combination in the innovative IT-centric Silicon Imaging SI-2K Digital Cinema camera. It delivered over 11 stops of dynamic range, flexible connectivity and film-like digital content, which could be easily inter-cut with traditional film footage. Unlike modern HD cameras, which develop and compress colorized imagery inside the camera, the Silicon Imaging SI-2K streams 2K (2048x1152) data as uncompressed raw “digital negatives” over a standard gigabit Ethernet connection.
An Intel Core 2 Duo processor-based computer embedded in the camera or tethered to a laptop up to 100 feet away, processes the digital negatives, where they are non-destructively developed and colorized for preview using the cinematographer's desired "look" for the scene.
 The digital negatives and "look" metadata are simultaneously recorded to hard drive or solid state disk where up to 4-hours of continuous footage are captured on a single 160GB notebook drive; this is the equivalent of 14-reels of 35mm film which has an associated cost exceeding $25,000 for materials and processing. The recorded files, can be immediately played with the target color look at full resolution, without the need for film scanning, tape ingest, format conversions or off-line proxies.
A customized camera support and recording package had to be built to meet the unique form factor demands of the Slumdog shoot. . They enlisted Pille Film, of Wiesbaden Germany, to create a custom solution which included a gyro stabilizer for the base of the SI-2K Mini. Instead of using the traditional film-style camera body, they elected to use Apple Mac book Pro notebook, running Windows XP, for the recorders, and built them into ruggedized backpacks, to be worn inconspicuously.
Stefan Ciupek, the show’s technical supervisor and additional camera operator, coordinated the design and modifications of the camera system with Wolfgang Damm of Pille, whose team worked around the clock to get the 2K Mini rigs built.
