"The Matchbook Mystery", a 2009 National Film Challenge short
 

Our entry into the 2009 National Film Challenge. We had the theatrical premier at the Terrace Theater on James Island this evening.

We used two cameras, a 5D Mark II running Magic Lantern with a Canon EF 85mm f/1.2L and a stock 7D with a Canon EF 50mm f/1.4. Both cameras were in 1080p30 mode with a 1/60th shutter and typically f/1.2-f/2.0. All of the rack-focus moves were on the 5D using a Cinevate Durus follow-focus, which didn't cooperate well with the 85mm's focus-by-wire system. They mixed together well after the extensive desaturation; the color balance between the two was widely off even with identical temperature settings.

Audio was recorded on the 5D with Magic Lantern, using a juicedLink CX231 preamp and a AT875R in a Rode blimp. The in-camera gains were +0 dB analog, +12 dB digital. The 7D's audio was used as a guide track to align the clips, although there really wasn't much shot with the 7D.
