oops, bottom 2 paragraphs should read - in real terms, including the Nuiquist limit in the calcs, the resolution is actually half this or 1.18 Mp of real resolving power in the optical system, still less than that of the good ol' tech pan. If one can assume then that a stated 16Mp camera has a little over half the actual resolving power of the tech-pan, could one not be excused from concluding the tech pan shot is equal to a 24Mp image? (1.7/1.1 =1.44 -ish) 1.44 x 16 Mp = 23Mp) Would not one then conclude a 4000 ppi scanner producing a 4000x6000 pixel (24Mp) scan is actually gathering equally legitimate data as a 16Mp digital camera? my bad. cut, paste, cut, paste.. spellcheck? nah! post. read. damn.. k
