I think that we may very well be close to the point where technology out works the human eye. It won't be long before resolution is less important than the physical relationship between the human eye and the printed image. Yes, we will be able to make images within a razors edge of perfection, but will we be able to recognize this perfection without massive projections or printed images?
The future is pretty bright if you ask me.
Maybe we have already had the best, maybe there will never be any digital image as fulfilling as what a lightbox, slide and loup gave us. It's tough to believe there will ever be any digital imaging that will converse with our eyes in the same way.
