This is the rig we used to create the HDR footage in the first test. It’s a miniature 3D prototype rig (Element Technica) that is being developed for 3D on Steadicam. The unit is wonderfully small but seeing as Canon’s don’t work very well for HDR we’ll need a bigger one. We started testing with a 50/50 beam splitter mirror but trying to align the cameras is very difficult, and it would be a bitch to use on set, so with the plethora of 3D gear around at the moment the answer was simple.
