Let me guess, that must be the University of Otago at Dunedin. Not just a pretty face to a roving camera.

I reckon there is somebody over here in Melbourne who can help. Contact SMBooth here on APUG; he's built several pinholes (including an anamorphic), and — sacré bleu! — even converted a Polaroid instant camera to a full-fledged 5x4 camera. Ever a skilled tinkerer, I reckon he'd have an idea. At the moment he's on a weekend photography trip away.
