Push HP5 with Agfa Atomal?

Hey danke! Es hat funktioniert! *froi* Die Entwicklung war zwar ein ziemlicher Nervenkitzel, aber als ich dann die Bilder sah war die Erleichterung groß*g...

Hello, The subject line pretty much says it all. I have two rolls of Ilford HP5 film that I’d like to develop using Atomal and push by two stops. Unfortunately, the Atomal instructions only list extended development times for Agfa’s own films, and for the HP5 they only give the time for standard development. As the subjects are quite important to me, I’d rather not just experiment at random here. But I don’t necessarily want to buy Ilford developer just for these two films. Does anyone have any idea or experience with this? Or can I calculate the extended development time based on the standard development time? Thanks in advance! =) Spark

Hi Spark, Agfa Atomal is roughly equivalent to A49, so it works quite well for pushing. Pushing by 2 stops – normal development time multiplied by 1.33? Or rather, 1.77 straight away (...I did a quick calculation...) Regards, Uwe

Hey, thanks! It worked! *yay* The development was quite a nerve-wracking process, but when I saw the pictures, I was so relieved *lol* Thanks again!! :ph34r:
