Ultra Low ISO Film

abruzzi · Mar 10, 2020

I shoot a lot of sub-50 ISO film, or higher film with ~5 or more stops of filtering. I don’t treat it any differently than faster films other than the fact that I can shoot wide open in bright sunlight. Most of my shots are outdoor in the bright New Mexico sun, so I don’t know whether you can get similar light in London.

Testing a newly restored and serviced Kodak Retina IIa with Svema/Astrum MZ3, at 2 ASA and processed by inspection (under safelight - its totally red blind) using Xtol stock. This MZ3 stuff is capable of delivering remarkable detail and tonality, if processed correctly.

How is this for a low speed film?

What time did you use for developing? Let's just say my first crack at MZ3 was nowhere near as successful.

5 minutes in Xtol stock. As I mentioned, I developed it by inspection: pull it out of the developer around 3.5 minutes, and then I left it a bit longer. Under safelight, of course.

Tom, I’ve been asked not to say as it’s not yet available.

Is there any update available, on this film you've been tesing?

sounds to me like it was the Lomography fantome 8.
I got myself some but haven't shot it yet.

At one point ILFORD investigated producing a 'Delta 25' film but I think they decided there wouldn't be sufficient demand or too much competition with Pan F Plus.

Delta 25?! Shut up and take my money!

I use to shoot Ektar 25, but you need a good tripod. It was super fine film.

I've found with iso 25, on average you can get a 5.6 or 4 at 1/125 if there's enough light. I've done some handholding at iso 12 as well.

Thanks Nodda, nice work!

The film is ~10iso, no worries if nobody is interested in discussing ideas, I imagine a cool low iso idea will come to me as soo as I finish the roll.

If you're talking about B&W, I'd suggest a compensating developer to keep the contrast under control. I've been playing with Beutler recently, which seems very promising so far in that regard, but there are tons of low-contrast developer options

Yeah, I wouldn't call 25 - or even 10 - "ultra" low. 3 and lower? That's ultra low.
