My name is Trond Kjetil Holst, I have been using pinhole cameras since 1984, so I have my 30th anniversary as a pinhole photographer this year. I live in northern Norway where the summer is light and the winter is dark. I have built many cameras, mostly of cardboard or foamboard, but a few of wood as well. Most of them use 4x5" film holders. I use film all the time. My biggest camera (so far) is "The Giant Mobile Camera". Image size 125x250cm (50x100"). I hope to become more active here at APUG, to be honest I have been "sleeping too long".
