Kaveh - thank you for your reply. It makes perfect sense that fringes recorded in a swollen emulsion will be properly oriented for replay only when said emulsion is again swollen to the same degree, but I still look forward - as I am a very visual learner - to viewing any visuals you would be willing to create and post. Loosely understanding this on a broad conceptual level will be nowhere near as valuable as seeing these physics laid out technically and specifically, and I thank you for being willing to aid myself and others in visualizing what's occurring here!
As far as index-matching with water is concerned: this was an experiment in simplifying darkroom work, and one that I'm glad only consumed a few scrap strips of film. I guess if index-matching was as simple as using good ol' H2O, then this would be by now a commonplace thing
Oh, well... That's holography as I know it; First learn 1000 ways to do it wrong, then land on one or maybe two ways to do it right
