Hello John. Hello Marilyn.

Though you could tape the lens to a box, I find using a view camera much
easier because at large apertures you do need to be able to change focusing
position. And with large apertures in bright light, it would be a little
hard to move your hat/shutter fast enough.

To determine the f/ stop is easy enough: f/ = focal length divided by the
diameter of aperture. And paper is about ISO 6.

I've used fresnel magnifiers to good effect as well.
