So I read in an old thread here that basically the two biggest factors to picture resolution (after format size) come from the lens: aberrations and diffraction. Don't stop me yet. I went on to read that the smallest point resolution possible is roughly the numerical equivalent of microns to whatever f/stop your using, so if I'm stopped down to f/32, I can't have a light point smaller than 32 microns. How accurate is this? Based on this reasoning, an f/1000 pinhole should have no light points smaller than 1mm, but prints from one show that it does have more resolution than that!
What am I missing?
