Do IB prints deteriorate/degrade in any way, as far as anyone knows..? Or do they always maintain there exact image qualities for an indefinite period of time?

Another quandary...When theaters played the movies in the day, how does one determine, or even know, what equipment was used to display said movie in said theater? Was there only one professional projector used for every theater in this, and other lands? If a certain projector used a certain type of bulb, or other piece of equipment, could that have tainted the way the filmed look in any way? Is it possible that the screen itself could have displayed the image differently from one theater to another?

It's really quite amazing to think of how many variables could have played a factor into what each of us saw, or thought we saw, when we saw it. It must be factored in. Just because a certain person says "This IS how it looked in 1977" doesn't always mean that is how it looked to me, or to others who saw it at there local theater. Now if we all saw the same movie, in the same theater, using the exact same everything, then, and only then, could one, or a group of people say, "This is how it was" IMHO
