I have an original bottle of Rodinal(pre-Agfa demise) and a bottle of Adox Adonal and can't tell the difference. Also, the old Rodinal still works just fine. The big question is still there, "Which substitute is the closest to the original Rodinal or at least the last/best variant"? B&H has and ad that says, Adox Adonal, but shows a bottle clearly labeled Rodinal. JohnW
