The trouble is the words we use like focus, don't really apply to a pinhole. A pinhole doesn't focus to a point, it doesn't have a focal length, it works by only allowing a narrow ray through. |
So, basically, a bunch of us have been using the word focus the way creationists and IDists use the word theory. See, the way I was thinking of it was, "focus" is a matter of degrees. A particular image can be blurry but useful, a slightly less blurry one more useful, etc. I wasn't thinking about it in terms of focal length or the mechanism producing the image, just how clear the image produced is.
Looks like I need to read up on optics.
WRT to the camera link: there really are genuine CCD devices using a pinhole though, right?
