Patrick;

The Metol equivalent of Rodinal that you were working on is very similar, if not identical to Kodak HDD, a developer sold many years ago. It was quite stable.

PE

Kodak HDD wasn't stable, like Ilford's Hyfin, and Neofin Blue etc it had to be made up just before use, the very low sulphite level of these developers means they need to be used within an hour of mixing.

So the opposite of Patrick's formula

Crawley noted that Kodak HDD really worked best with Panatomic-X and wasn't really suitable for all films, Tetenal recommended their Windisch formulated HDD for Adox films, and Hyfin was particulary suited to Pan-F and FP3.
