Re: wideangle, telephoto, etc

The acceptance angle or field of view at any pinhole-film distance is a
function of the width of the negative. The optimal image is the shape of a
hemisphere centered around the pinhole. Whether you have "closer up" or
"further away" depends on how much of the potential image is covred by the
negative.
