Pinhole Focus

I made two assertions; 1) that at a given extension you will get the same
image regardless of pinhole size and 2) that the sharpness was the same for
each image.
I will stuck to the first and admit I'm on shakier ground on the second.
I used TMax 100 4x5 film and shot a scenic, a saguaro cactus at about 25
feet. Examining the negatives and proofs only with a loupe, they appeared
to me to be of similar sharpness. Also, I will admit I didn't shoot the
whole series of pinholes but only a sampling.
I plane to redo the experiment with the whole series to see if I am
mistaken.
Regardless of the results, doing it is fun and enlightening!
