I recall reading about the developing formulas, something about a Lumiere (autochrome?) developer formula being suitable. Probably in the linked PDF a few posts back. I emailed Hans Bjelkhagen and he sent me some files/articles about it. If you are interested, PM with your email and I can send you them. That goes for anyone else as well who might be gleaming this thread.
Looking forward to trying this, albeit down the road a bit. Not prepared to pull the cord just yet.
By the way, if you're interested in attempting integral photography, that's another realm where I'd need somebody to split a minimum order on a fly's eye array. However, better focus on one thing at a time, eh? Hahaha...
