I'm not sure what you mean. Changing the size of the pinhole, without
question, changes the sharpness of the image, making it different, so niether
of your assertions are correct. Eric Renner's book displays this with a
series, and can tell you that this is the case from first-hand experie

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
