Fomapan 100/Arista EDU Ultra 100 in 35mm

[Max Power]

I've been using Fomapan 100 in 120 for a few months now and really like the results. I've been considering picking up a 100ft roll in 35mm as a replacement for APX-100. My only worry is about how badly it curls when dry.

The only 'problem' I have with Fomapan 100 in 120 is that it has an unbelieveable amount of curl, lengthwise, when dry; the negs are sometimes a real challenge to get in the negative holder.

Has anyone found that the curl is bad in 35mm? It stands to reason that it would be the same in 35mm and 120, but I'm wondering if anyone has any first-hand experience.

Cheers,
Kent

If you hang it to dry with weighted clips, you shouldn't have much of a problem. I find Foma 100 no curlier than Tri-X dried in this manner.

The one roll of 35 mm .EDU Ultra 100 I've processed so far agrees with Justin's results -- and mine was from a bulk roll.

Worthy of note, some folks over on nelsonfoto have been noticing that at least some curly films (Efke R100) seem to flatten better if they were processed in a relatively high sulfite environment (D-76) than in a low-sulfite developer (Rodinal 1:50 or 1:100). There might be a gelatin conditioning effect from exposure to sulfite, though that isn't yet confirmed. Should be easy to check, though, if you have a curly film and a couple different developers on hand.

My experience is with the ISO 200 material from Arista.EDU / Fomapan, but I've found that the 35mm material doesn't have much curl at all (it's about the same as Ilford or Kodak). The 120-format stuff, on the other hand...

My understanding is that Foma uses a different base for their 35mm and MF films, so I wouldn't take the MF results on curl as indicative of 35mm performance.

Going from theory to practice, my experience with Foma's 35mm films is similar to what others are reporting in this thread. I've shot most of a 100-foot bulk roll of Fomapan 400 and smaller quantities of Fomapan 100 and 200 (most from factory-spooled cartridges, but some Fomapan 200 from a bulk roll). I've noticed no curling problems with these films. I air-dry my film hung from a clip with a film clip as a weight at the bottom.
