    FP4 underexposed by 3 stops


    wait, i messed up my info.

    ok retype:

    underexposed my FP4 by 3 stops, very embarassing!

    I made this post and was for no logical reason typing about pulling film.... I did see a black cat this morning!

    Maybe now that I have turned my FP4 into iso 800 film.... maybe that package of Microphen will be handy.

    Would be nice to save these shots, just 2 of them.

    reccomend some developers that wont turn the negatives into a grain blob ?

    That's a push, not a pull...

    Microphen-
    I'm sure that wasn't on the list earlier-
    that should do it, but don't ask me about times...

    Though you could always underexpose another sheet, and do a test...

    I do have some Microphen

    I looked at the massive development chart.

    You know what it said ?

    it said:

    "You Idiot!" LOL

    Or perhaps you could try some Diafine? Either way, I would do a test with another couple of sheets (under)exposed in the same way and process one in Microphen, the other in Diafine and see which one gets you closer...

    P.S.

    I used to push FP4 (no plus!) in Microphen back in the 70's and I think I remember doing it at about 15 min... I have a feeling that in your case a good starting point might be 18-20 min. If that still comes out thin, you can try raising the temp to 72 F and go gentle on agitation.

    I hope you salvage your film.

    Try Rodinal 1:100 for 40 minutes with agitation every 30" for first 5 minutes, then every 10 minutes thereafter. You may get a bit of extra density on the edges but it should even out development in the center 95%. Test first.

    Brian,

    12 minutes in Microphen at 70 degrees should give you a scannable negative.

    Microphen is a speed increasing developer (your name is Speed, isn't it?).

    You can expect the image to be there, because exposure at 800 can be salvaged by long development in HC-110B. (Please don't ask me how I know this.....)
