Kessler / Hurricane 3D time-lapse

This is a behind the scenes time-lapse of the Kessler Motion Control System comprised of the 3′ Cineslider, Oracle Controllers, Camera Control Module and Turntable for a sliding shot with pan. The Genus (Manfrotto) Hurricane 3D beam splitter Rig is supported by the Sachtler FSB4 head mounted on the Kessler hihat. Two Makro-Planar T* 2/100mm Zeiss lenses are used for this shot with two Canon 5D Mark2 DSLRs. For reliable stereoscopic DSLR work, everything needs to match, including all camera setting. The Kessler Camera Control Module is programmed through an Oracle Controller via ethernet for precise control of interval, with many advanced features. I made a splitter so a single Camera Control Module will trigger both cameras at the same time to maintain sync. The three Oracle controllers seen here are not all in operation, nor needed for this shot, but happen to be tied together for other applications. The Kessler low-profile feet allowed me to place it right on the ground.

2 Anton/Bauer Dionic 90 batteries mounted on their QR-Hotswap-GM power all, and allow for continuous power – which I won’t need for this shot, but really comes in handy for longer shots. In this setup they give me some needed counterbalance and also ensure I don’t have to power down to swap a battery, which I like to avoid to keep things flowing when there is so much going on.

A shared external power source aids sync – I distribute power from an Anton/Bauer battery via their MultiTap with LP-E6 to D-Tap Power Cables from HotRodCameras, engineered to protect the battery by not draining it fully, which is very cool, though not needed in this scenario, and the Anton/Bauer QR-DSLRs would work fine here.
Provided all settings match, two (or more) Canon 5DMark2 cameras will hold sync for time-lapse, and for video up to a point – around 5 minutes. The external unified power source helps hold sync, which is tricky with cameras that cannot be genlocked. I’ve found that powering both cameras up at the same time can be important, and having one power source makes this possible. One power source makes things soooo much simpler. Long lasting, reliable, one charger. So I’ve pushed that as far as I could, and using the MultiTap and Extensions, I’ve also got the Oracle Controllers and 7-inch Marshall V-LCD70-ATSC juiced.

Litepanels LED lights were used to light the scene, including a few SolaENGs, a few 1x1s, and a Sola6 – which I am liking a whole lot. With the exception of the Sola6, which needs AC, all lights were also powered with Anton/Bauer Batteries, which will keep these low-power lights in action all night – I love that.

Manfrotto also helped out here with various support arms for lights, and for dual tripods to support the entire system.

 

A little absurd to see myself here, and think of the complexity of rigging up the shot which meant planning the motion control move and programming the Kessler system for Dolly and Pan, predicting a speed, interval, and shutter speed for the final shot, aligning the Hurricane Rig and Zeiss lenses in the dark, and in this case without a 3D monitor, art directing and building props, and then lighting for a long exposure sequence… whoopa. Lots to keep straight. Luckily I had my stereographer pal Stuart Sperling along for the first part of the night to help align the Hurricane Rig so I could concentrate on other things. The remote light control for the Litepanel 1x1s were a big help when a subtle change in lighting makes a big difference with a 2 or 3 second exposure.
