Re: Digital cameras & depth of field (my experience)

Dan, come back to earth. We are talking photography here, not rocket
science. I give you this quote from
http://www.pinhole.org/about/index.cfm (which you would do well to
visit).

"Pinhole images are formed by a beam of light, the diameter of which
governs its sharpness. The diameter of the beam is determined by the
diameter of the pinhole...so, a really big pinhole will make a less
sharp image and a very small pinhole will make a very sharp; but not as
sharp as a lens, image."

The pictures on exhibit in the gallery there are quite amazing.
Dimensions, relative f-stops, and other detail are available there too.
And by the way, I made a pretty good living with that antiquated
ray-optics for thirty years. I shall not desert it now!
