I'm really tempted to try making a pinhole camera from one of the wooden cigar boxes that my local tobacco store is always giving away. I'd love to make it work with 35mm or 120, but I think 4x5 would be easier to fashion.
I think two or three cigar boxes stacked would make a great 5x7 camera. That might be my next project. If I had any construction ability at all, I would have built this camera from scratch, as I hummed and hawed for weeks looking for an existing box with dimensions close enough be adapted to accept a 4x5 film holder.

Ansel Adams had the Zone System... I'm working on the points system. First I points it here, and then I points it there...
