FP4 vs FP4+

Discussion in 'Black and White' started by don_wilkes, Feb 14, 2005.

  1. Does anyone recall when Ilford changed the designation (and,
    presumably, the formulation) of FP4 to FP4+?

    I recently discovered an old, exposed roll (from a bulk load)
    accidently left in with a bag of ancient, funky film cans. It came
    out very thin and fogged, even though I added 50% to the development
    time for FP4+. It may be too thin to print conventionally, so I may
    have to have a buddy scan any interesting frames for me, and print it
    that way.

    I have a hunch this roll may date back to the mid-70s, but won't know
    for sure until I can see a contact sheet. Most of it seems
    portraiture, and I'm hoping I can identify the subjects.
     
  2. I think the "plus" version came out in the very late 80s or early 90s.
     
  3. I would also be interested in knowing about this. I think I have two 100 foot rolls of FP-4 in my freezer. It was purchased as Ilford was making the switch.
     
  4. Search the archives or my postings. I had the same question a few months back.
     
  5. I'd gamble on '88, but not with a lot of money.
     
  6. Interestingly, J and C photo lists ORWO pan (FP4)-

    What the difference is between FP4 and FP4+, I don't know-
    I was mostly a Kodak user before FP4+-

    but I intend to find out,since I shoot a lot of FP4+ lately
     
  7. Thanks, Vinny -- that was exactly what I needed. The final comment in that thread should settle it, coming from our friendly Ilford rep:

    The Plus line of films were introduced right around 1990.
