There's not that much difference between them: both POTA and Delagi 8 (a
modified POTA) consist of Phendone and sodium sulfite. The difference is
Delagi added benzotriazole (restrainer/antifoggant) and borax. POTA was
originally intended to record very high contrast ranges (like atom bomb
blasts.) For normal scene contrast range of 7 or so stops, Delagi will
give "normal" results.
