Re: Pinhole Focus

Ian -

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 experience.
