On top of my P.90/2 Stenope pinhole camera I have mounted a FOTOMAN finder. The mask that came with it is metal and covers way more than the coverage of the panoramic pinhole camera. Metal mask is .011 inches (.29mm) thick and painted black.
Advice on how to fabricate another metal mask to match the coverage of the pinhole's panoramic image needed. Figuring out the size of the rectangular opening in it is easy. Fabricating the metal mask, I'm not sure where to begin.... aluminum, steel, brass, or ? .29mm shim stock? How to cut out the shape and the opening?
thanks
