Digitize them already.
What is the problem?
Some of the older animation cels are acetate based and have yellowed with time, others are brittle, some have the paint flaking off.
They need to stabilize the acetate on some, others have turned to almost a translucent putty and those are unrecoverable at this time.
Yeah, this article is bogus and leaving out a lot information. Of course Disney has preserved every scrap they can. There is something else that was supposed to be conveyed, but wasn’t, due to shitty reporting by fake news outlets.
As with any older painted item they must be cleaned before having anything done to them. Film, fading, color matching.....it is restoration work at its hardest
They are whining about preserving the “magical” originals. I have news for them, stuff gets old and falls apart. When the Mona Lisa becomes unviewable, there will be plenty of high resolution images available.
