when i was a kid, my father used a different a-b developing method, mixing the chemicals himself, but he doesn’t remember what it was, and cant find the book he got the recipe from, and it allowed you to shoot hp5 at 400 speed, and process it with essentially the same method as diafine. anyone happen to know what he was using, or was he essentially making his own diafine?
