Victoria Cooper & Doug Spowart also have done extensive Camera Obscura work. I spoke to them in Wellington last year, and they are completely dedicated to the medium.
They have also turned a whole room into a pinhole camera obscura for a project of theirs .One of their most notable stories is of converting a van into a large pinhole camera and then touring their home country Australia with it.
They have some impressive results .... [font=Times New Roman][size=3][color=#800080]Gallerie[/color][/size][/font]
