Re: making a pinhole

Has anyone ever made a pinhole by photographing a circle?

I was thinking that if you can make a focal plate by photographing a
printout of one, how about making a pinhole using film in the same way!
It would be accurate, have negligable thickness, perfectly round and you
could easily choose the diameter of the hole. Other shapes become instantly
possible, stars, ellipses, squares, the sky is the limit.

Does any one have experience of this method or any ideas. It would
certainly solve many problems and I cannot see any being created - all
except one; is a dense negative sufficient to create a totally opaque
surround for a hole?

And if this is a perfect solution, I know that pinhole is not always about
perfection, but it would open up many possibilities. :-)
