Diagnosis please?

if, for instance, the pinhole 'blurr' was around a half a degree (a totally made-up number), then objects much larger than the pinhole could still be blurred if they were far enough away to subtend an angular view of a half a degree or smaller.

Yes! An even more eloquent way of expressing what I think I was trying to say.

Actually, if I took a little more time in the scanning, I could enlarge these images to a truly huge size without the film grain. Because these have soft edges you don't see the typical effects of enlarging, at least not with my workflow. However that work flow has no place in this forum.
