I've just finished making a 6x9 sliding box camera... the only caveats for me were that it had to be cheap (really cheap), use the 6x9 DDS that I've had in the cupboard for about 5 years, and the old brass, rapid rectilinear lens also sat in the cupboard for about 2-3 years. In the end, it cost me 3.50 for the matt black paint to blacken the inside of the camera, but other than that it was 'free' - made from plywood and whatever I had knocking around in the garage!

It's not a pretty camera to be sure...


But here's the second shot I made with it (paper neg, developed in cafenol).


You can find out a bit more about the camera, and the first image, at the Creative Image Maker blogsite (link below). I can't tell you how much fun it is to build a simple camera, shoot an image on paper then develop in coffee... and get a reasonable result
