Everyone has access to the older literature. Maybe a real book, or more likely the internet. Maybe we could share interesting facts, quotes, and history. I had no idea cadmium was preferred for its keeping qualities. I wonder if that's also true for silver gelatin emulsions. What I know about relates to emulsion color and characteristic curve control.
The only potential downside I can think of is that this might turn into dueling references. Cross that bridge if and when necessary. Fingers crossed.
