I am aware of the stability of electronic images, but what are your thoughts on films?

My work has almost always been in black and white, and I have always done m y best to produce the most archival work that I can. The process is not that dif ficult in black and white photography. Now I am wondering about color...

Using a standard pro-lab for processing, what is the expected life of the p opular color films in use today? How long before colors begin to shift or fade? Is there a chemical process I can put the film through to prolong the image? Do negatives preserve better than chromes?

Along the same lines, watching Hollywood movies from the 50s and 60s you do n't have to be an expert to see that that the films done with Kodak are fading f ast, while the films done in Technicolor are still rich and vibrant in color.
