    That looks realistic according to my experience, Peter. But use of deep contrast filters will complicate any predictability at long exposure quite a bit, in a manner that short exposures do not. The spec sheet doesn't give a clue about filter factors. Their wedge spectrum is based on tungsten light exposure, not daylight, so one has to somewhat careful interpreting it. I simply tried generic filter factors similar to FP4, HP5 etc, and it seemed to work.

    Foma 200 Reciprocity

    Measure 1 second on the meter...give 1.5 seconds
    Measure 2 ... give 4
    Measure 3 ... give 7
    Measure 4 ... give 12
    Measure 6 ... give 18
    Measure 8 ... give 28
    Measure 10 ... give 40
    Measure 14 ... give 48
    Measure 20 seconds...give 100 seconds
    Measure 30 ... give 175
    Measure 50 ... give 350
    Measure100 ... give 900

    1..............1.5............2.1
    2.................4............4.9
    3.................7............8.2
    4...............12..........11.9
    6...............18..........20.1
    8...............28..........29.3
    10.............40..........39.3
    14.............48..........61.5
    20...........100..........99.4
    30...........175.........172.1
    50...........350.........346.0
    100.........900.........901.2
    Thanks Peter. I will step into this domain using these guidelines absent filtration to keep it down to one variable and report back.

    Fomapan 100 is not particularly picky about exposure and development in my experience. I usually don't shoot for wet printing though, so I err on the side of caution and go for a slightly less contrasty negative. Most of the problems come from an underexposed negative, blocked up shadows are much harder to deal with than finding detail in highlights. So, out in the field I usually like to give it a little extra exposure if possible (sometimes wind or impatience prevents it) so that it doesn't matter if I forget about bellows extension for instance, which I usually have with very long exposures.

    When I first started using Foma 100 I wanted to test out the reciprocity failure chart (provided by Foma, I believe) and check for myself if it indeed topped out at 4 stops as it appeared to do.

    I setup this test and shot a scene where the measured exposure was 6 min, making the needed exposure close to 100 minutes. The resulting negative was quite perfect for my use, easy to scan, with enough density. And I used the chart ever since.

    An easy way to remember is that it needs 1 stop extra at 1 second, 2 stops after 2 seconds, 3 stops after 8 seconds and 4 stops at 100 seconds. I try to bring the chart always, but even now that I don't shoot so much anymore I still have 1, 2, 8, 100 lodged in my brain.

    Sequoiadendron Giganteum from 1868.
    Shot this on Foma 400@250, Sinar F2, Schneider 150mm 5.6 Xenar at f22, 1/2 sec.
    Developed in Rodinal 1+100
    Some unevenness from improper scanning...
    Not my fist shot on film, but my 5th shot in 4x5.

    Many, many nice shots here. Enough to inspire me to give Foma another try. Tried 200 and didn't care for it per se, but even the 200 shots here show it was more likely me and not the film. Doh.
    Foma 100 seems a consistent winner here. When I ditched Foma 200, I went back to Ilford FP4, but the prices of FP4 have recently shot up quite a bit. May do another box of Foma 100 next. Thanks! to all of you for the ispiring work.

    I used some 8x10 Foma 200 rated at 160 yesterday. The metered exposure was 14 seconds, I gave 48 seconds of exposure, as per the info I posted above. The negatives are still drying, but the density looks as expected.

    This is my first exposure with 4x5 film. I'm pleased with the shot I got.
    Foma 400, Schneider 90mm f8 at f22, 1/8, with polarizer.
    Development and scanning was done in local lab. They say they use Tmax Developer. Imacon Flextight scan.

    Reciprocity is really a problem. I was in a cathedral the other day. The longer exposure times due to reciprocity produce very dense lights. Especially the light sources. - Although I work with Rodinal 1+100. - However, adjusting the development times reduces the contrast over the tolerable. I haven't found the right recipe yet.

    I like Fomapan 100, I practiced a lot with it and recently ordered 200 sheets. Fomapan allows me to do affordable experiments.

    But now I am changing to FP4Plus and HP5Plus. - Obviously it is getting more serious with large format photography ...

    Anyway, these pictures were taken with Fomapan 100@50, dark yellow filter 023, R09 1+100, 30/30-5, 20°C, 11'30''
