Oh yeah, Tetenal Blue, I'm sure Everybody knows how that works..(teeny sarcasm).
You'd think he'd try ID-11 or D-76 or even Rodinal. But hey, if he wants to use a variant of an uncommon developer to test his footnote, have fun. Its just not very useful review to most people.
(In all fairness, I still have some Tetenal Blue in vials, don't know if they are any good still, maybe I'll Test it with some Kodak Plus-X Aerocon...)
