It is said that with this film you really have to try to get the exposure wrong. I agree.
From Wikipedia: “HP is a cubic-grain black-and-white film from Ilford Photo with a long history. It originated as Hypersensitive Panchromatic plates in 1931.”
This film is a true classic. Anyone shooting monochrome sooner or later tries it out. For good reason. Its nominal 400 ASA and nice grain and tonality make it the perfect all-rounder. It can be easily processed. It is readily available. And what amazes me the most is that it is one of the most robust films in the world. I present here pictures made with Ilford HP5, the previous version to the current HP5+ Ilford film, which had expired in 1989. Yep, that’s 21 years ago, more than some of you are old :D (And I still have some rolls of that 120 goodness left!).
The HPs are legendary for their pushing capacity. I have seen HP5+ pushed to 64000 ISO. Amazing, eh?
I honestly have no idea to what ISO I pushed my HP5 when making these shots (and what nominal ISO it had to start with after so many years of expiry under unknown storage conditions!), as I Don’t Think, Just Shoot!!! whether it be a dark gloomy winter day with some medium format slow platic lens or sunny summer with fast glass 35mm.
Whatever low-light punishment you inflict on this emulsion, just semi-stand develop it in Rodinal 1+200 for 2 hours (or 1+125 for 1 hour as I did with these two rolls) and you’re all set!
Ilford HP films. Classic.
