Well well... that's ok Bill.

Maybe instead of quantifying the results, we should be content with qualifying them. I would think that by comparing one emulsion to a manufactured film you could tell a lot from that. A piece-of-junk shoebox monochromator might be surprisingly illuminating (that's not a pun), and building it sounds like not a bad way to spend an afternoon either.

But anyways, I'm not about to go testing emulsions when I get home, I'm just enjoying the discussion.
