I'm not discouraged in making my own emulsions, but what I'm saying is that will a group of individuals ever be able to achieve the perfection of say, the slide films of Kodak/Fuji? It seems like the R&D necessary to produce something with that high of quality is unattainable today, without the market incentive and the years of work towards these excellent products.

All I'm saying is, can the patents and published information lead to such a result if an individual or smaller operation took up the task?

A 100 years from now, will they publish this information? IDK, but no one even knows how to operate the original autochrome machines, as an example. Perhaps if they had left detailed instructions for the public, we could.
