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!
