I finally got around to renting the Burtynsky documentary, Manufactured Landscapes, from Netflix. It's very much worth seeing. The DVD includes a selection of stills with Burtynsky's commentary that is very interesting.
That scene where he's using the Technika upside down is completely normal, by the way. If you're photographing from an elevated vantage point, as he often is, and you want front drop, the easiest way to do it is to mount the camera upside down using the tripod screw on top of the camera under the accessory shoe, because the zero position of the front standard only allows for rise when the camera is right side up. The back rotates 360 degrees, so it can be oriented normally when the camera is in any position. If I know I'm going to need front drop and don't plan on using the viewfinder that normally sits in the accessory shoe, I even mount a second QR plate on top of the camera.
