That's as > much laziness as policy, though :-) . Why is any of this newsworthy, or surprising? It's always nice to have lots of bright, white light to look at photos with. The root problem, of course, is that this same energy (the light, that is) is also hastening the breakdown of the molecules that compose the dyes and inks that form the image in the first place. So it's a tradeoff, as usual. This all gets back to one of the fundamental principles of quantum mechanics. It is impossible to observe a thing without interacting with it. That interaction always involves an exchange of energy. And in the case of photos, the energy is invariably destructive to the thing being observed. If we wanted our photos to last forever, we'd keep them in the dark. But then, what purpose would they serve? rafe b. - Turn off HTML mail features. Keep quoted material short.
