My camera will shoot a good 3x4 negative, but the 4x5 version is a pain to work with. So what I think I will do is make a daylight contact printer to print 3x4 negs on 4x5 paper. Probably use a 4x5 mask with a cut out 3x4 oval to make retro portraits. If it is works okay and it should, I might go with 5x7 prints or even 8x10.. Can probably build a view camera.
So anyway the enlarger will work I am convinced, if you can get the focal distances right From pinhole to negative holder and from pin hole to film holder. And yes Terri this the uglist thing I have build yet, but it does have a warped beauty.
I have no experience with trying to tone rc can it be done. If not I guess I'll have to print wash it with oils. Or go with a fiber based paper.
