Hallo, wer hat denn Erfahrung mit Rodinal zur Positiventwicklung, wenn ja, welche Verdünnung ist da empfehlenswert. Viele Grüße Albrecht

Hello, Does anyone have any experience using Rodinal for positive film development? If so, what dilution would you recommend? Best regards, Albrecht

Hmm, at a time when Rodinal is practically worth its weight in gold because Agfa has stopped supplying it, these words almost sound like blasphemy :-) But never mind: use the highest possible concentration (1+10...1+20) because otherwise it takes too long, just like my reply. The rest is a matter of judgement. Best regards, Mirko

Hello Mirko, Thank you very much for your advice, but it doesn’t have to be the original; as we know, the APH 09 is almost identical. Best regards, Albrecht

I’ve just had a litre of APH 09 sent over; it seems to me to be quite comparable to Rodinal. I actually only use Rodinal as a one-shot developer, for experiments and when I’m just pottering about. As a positive developer, I reckon it will behave almost identically to Ilfotec HC (i.e. around 1+29 for PE papers, or according to personal preference).
