Or, maybe, I am just being= thick-witted. You know seem to be saying that technical=20 differences between analog and digital projection=20 do not matter to a non-critical and non-technical=20 audience. I had thought that you had earlier=20 stated that digital projection was clearly a cut=20 above in quality so that even a non-critical=20 non-technical person could see the difference. I know precisely the validity in Jim's=20 remarks. I have seen top-end digital projections=20 and I have seen top-end ama;pg projections, and=20 even someone who had never before seen a slide=20 show could see the difference -- the analog is=20 clearly brighter and sharper and the colors are truer. SOMEDAY, digital projection will catch up,=20 precisely as SOMEDAY digital cameras will equal=20 the quality possible from analog. For most=20 purposes, digital, due to its convenience, is now=20 more capable than analog but, still, for raw data=20 storage and transmission, analog still outpaces=20 digital by a significant margin.
