    Any tips on shooting expired FP4+? Not a film I have ever particularly got on with or enjoyed, but I just acquired a few rolls (35mm) and may as well use them. About 10 years out of date.

    I've had some success with Rodinal (actually R09) at 1:100 stand developed for 1 hour. This roll was 7 or 8 years out of date if I recall correctly. The tone range gets a bit squashed but at least it's something...

    Interesting. There was a time when I could click through B&WP and generally identify FP4+ shots from their look, which I considered to be somewhat flat and lacking decent contrast. Yours though doesn't look that way. All I have for home development is DDX, and that's probably expired too. Haven't developed at home for about 4 years due to moving house, lack of suitable space etc. - need to put that right!

    Now there's a thing!

    I always thought that the idea with expired film was to amend the ISO based on the age of the stock and increase the exposure accordingly, but to process the film according to the original guidelines for when it was fresh.

    Have I got the wrong end of the stick?

    Cheers, Jeff

    That's what I thought, too.

    Off-topic a bit, I saw a trick to keep liquid developers fresh for longer recently.
    Empty a beer or wine bottle and wash it.
    Pour undiluted developer in.
    Fit one of those "wine-keeper" tops - the ones that come with a little vacuum pump. Seems to work.

    I've used some very old FP4 and just gave a extra stop exposure, (50 iso instead of 125) developing as normal. Worked fine.

    I'm currently using up some FP4 that was out of date about 9-10 years ago .
    Shooting it at ISO 125 , developing in Rodinal .
    No idea on it's storage as it was a gift , but i know it wasn't stored in a fridge , it's come out fine .

    Thanks all. I suspect I'll rate it at 50-80 depending on how much light there is and take it from there. :)

    Based on what I've read (unless you know that it's been refrigerated) then that sounds about right. Since it's only ten years out, I'd be tempted to go for 60-ish. Please let us know how it goes!

    Cheers, Jeff

    I was planning to shoot with filters, but with winter light that'd be silly shutter speeds or wide open. We'll see how it goes.

    Have any of you noticed cosmic-ray fogging when using old film? And, if you have, how can you tell that from other sources of fogging? Do the negatives look different, or do you need a densitometer plot to decide what's gone wrong?
