Ilford HP4 exp. 1979

Is HP5 the same as HP4 or did they change things?

    They did change things a bit.
    And of course, this film is about 30 years old, so it will certainly be different than new HP5.
    One query though - why are you posting this in the "Resources" section, which is designed for long term reference material - rather than the normal Black and White materials sub-forum?

    I'm glad you asked, because I'm not entirely sure where that is.

    I certainly wouldn't pay that much for expired film...

    Logan, you seem to have posted the same thread twice and have 10 replies on one and 5 replies on the other which means looking at two threads for the full picture. Maybe the mods can help and merge the two threads.

    Let us see what your results are when you develop the HP4.

    Logan, what success did you have with the expired HP4 that you bought seven months ago?

    Thanks

    I have some HP4, which also expired in 1979, in 120. I shot it at 50ASA and developed it in Rodinal for 6 minutes, with reasonable results. I wouldn't use it for serious photography though because the grain had clumped in some areas.

    Found a photo taken on 1979 expired HP4 on my Yashica Mat.

    I'm curious what you all get from the film. I stopped checking the base fog and stopped using the HP5 72 exposure 35mm film I got in the early 1980s. Now I'm just saving it in the canisters for its unique historic appeal. Film base got up in the 0.6 range.

    Well the cat looks pretty serious to me. I can't see the grain clumping and certainly not in the important area which is the cat. With expired HP4 it is said that the cat in question will stay young forever and only his/her picture will get old. Not a bad exchange in anybody's book :D
