Anyone use film lower than 50 ISO?

[Pirate]

I would like to play around with a slower film. I'm in the desert a lot and even back home in Germany I could use it on some of the sunny days.

Does anyone have recommendations of film below 50 ISO? Black and White or colour, doesn't matter.

Thanks

I use Efke 25 for B&W. Nice film, but a bit contrasty in direct sunlight. Real nice in the shade or on cloudy days.

Some people rate Pan F+ @ EI25 -- it's a terrific film, I've had nothing but good luck with it.

Rollei Retro 25 is another choice, too. Both sing in Rodinal.

What are you looking for out of an ISO 25 film? Numbers aren't really everything, you might find that a film like Acros or Tmax 100 is actually finer grained and sharper than the 25 ISO films. If you want a traditionally grained slow emulsion, Pan F+ is the best. I have spent a lot of time trying to like the Rollei and Efke films, but I have found them to be quite fussy (curling, scratching, I have even had the emulsion peel off the film base on Rollei R3! And this is using their own chemicals and following instructions to the letter).
So for my money, I would stay stick with Fuji, Ilford or Kodak...

I like shooting 100 ISO films, especially out here in the desert. I'd like to try something slower, like down to 25 so I can get more adjustment from my camera settings.

At 100 ISO, I only have 3 stops of adjustment. At a full Sunny-16 I can only go F/5.6 @ 1000s. I've got a 1.4 lens on my RF and would like to go down a little farther to give my shots some more feeling to the depth of things.

I like slow film so I don't need to shoot at 1/1000 the of a second and F4.

T-Max 100 is great at ISO 50. Add a ND4 filter and you are shooting at ISO 12.

Don't forget about ND filters. But, I like the slow films. Efke/Adox are very good and I'm just now getting the Rollei Ortho 25 down. There are the microfilms too.

Efke 25, Efke Ortho 25 and Rollei Ortho 25 souped in Rodinal 1:100 for 1 hour in standing technique.

Thanks for telling me about the ND filters, I didn't know about those. They may be just what I'm looking for!

 

[Pirate]

And those are 35mm films?

As said above Paf F at 25, Efke 25 or if you're feeling adventurous Adox CMS20 microfilm (or the Spur equivalent). It's a bit finicky to develop to good tonality though

Where do you guys get this stuff? I can't find any of it at my usual internet haunts.

Monochrom used to sell Efk, but don't anymore. Foto Impexx should have almost everything mentioned in this thread. If they don't have Pan F, Macodirekt does.

Ektar 25 (expired decades ago, but kept in a freezer all its life)

Pan F+ is the bomb. Efke 25 is nice, but not everybody's cup of tea. Also can be cumbersome in development, as others have mentioned. But yeah, use Pan F+ and you'll never look back.

 

[Melvin]

Pan F with a no. 8 yellow filter is effectively ISO 25, but you still develop it at ISO 50. And it looks great. With an orange filter it be ISO 12.

Well, round where I live...:

I usually have a couple ND filters - ND4 and ND8 - and for very sunny situations I can even stack them both and shoot at f1.4 on daytime. they are quite useful, one could use mostly iso400 film and be ready for pretty much any luminosity situation.

Their glass needs to be pretty good, though: mine are not top quality and I do notice a bit lower contrast when I use them. but it can really help on the desert shots!

 

[mackigator]

Nothing wrong with using ND and graduated ND filters (the latter for an SLR). I think they make you more flexible than switching to slower films.

You guys make me want to try some Pan F though.
