Re: 18 x24 pinhole/lens camera

I have an old DIY (Do It Yourself) Manual from the 1920's, I think, that
shows you how to make a quarter plate camera from scratch including bellows,
boards, dark slides, frame, brass fittings, etc, etc. It is quite a process
and you need to be quite skilled with woodworking tools. However, with
modern materials and equipment the work is made much easier

If anyone is interested I can scan the chapter and email it as a PDF file or
whatever. I shall just need a little time. Let me know if you are
interested.
