    Re: Fomapan 100, 200 and 400

    I haven't done a scientific study, but a few indoor exposures using FOMA100 with times of 1 minute up to 7.5 minutes indicate that the reciprocity curve is a suitable start point.
    Regards,

    Doesn't mean the same factor is necessarily equally applicable to their 200 and 400 films as well.

    Here's an excerpt from my practical testing of Fomapan 200. The actual results do not match the extremely pessimistic numbers from the manufacturer's "guesswork".

    Fomapan 200 reciprocity characteristics are supposed to be easy to test for so I tried. Well it wasn't so straight forward but three 120 rolls later here are some results:

    The exposure level I chase in landscape metering is Zone IV = shade side of tree bark, dark rocks, etc. The question becomes "what exposure time extensions must I give for long exposures so I get the same negative densities for Zone IV as for short exposures?" Answers obtained:

    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

    For photographs of dark scenes I don't apply the full reciprocity correction. I want the final picture to match the scene with empty black shadows, subdued mid-tones, and a few gleaming highlights. Remember also that the shadow parts of the scene will invoke reciprocity failure in the film but the highlights won't. Extending exposure causes a strong increase in contrast because the highlights keep building density but the shadows lag behind. This can be controlled by reduced development. But reduced development can cause a loss of film speed which calls for even more extended exposure; and so on. It is not so simple to make dark scenes look like bright scenes!

    I mean, it is a very steep curve with values like those:
    1s = 2s
    4s = 21s
    8s = 59s

    May I consider that chart as still valid?

    Thank you
    Yes, the published chart is reliable.
    The necessary compensation grows to 4 stops, but not beyond. I have done quite a few long exposures on Fomapan 100 and always used the chart, never had any problems. It does like a lot of light, better to err on the side of caution and give it plenty when in doubt.

    I tested if it really wouldn't go any further beyond 4 stops a few years ago:



    Chamonix 045N-2 + Fujinon 150/5.6
    100 minutes (measured 6m @ EI 32, added 4 stops to counter the schwarzschild effect) @ F22 1/2
    Fomapan 100
    Developed in XTOL 1+2 for 14 min @21C

    Color photo with Fomapan 100!

    Composite of 4 shots; 3 with antique Kodak RGB filters + 1 unfiltered straight shot to give extra shadow depth. 4x5 with my B&J View, CZJ 135mm/4,5 on a Packard shutter. Legacy L110 developer.
    Negatives digitized with my Nikon D800, raw edited with DxO PhotoLab, and composited with Affinity Photo.
    Already posted in the Tri-Color thread, but wanted to share here too. My first attempt at this technique. Excited to do more! And Foma 100 looks to be a nice film for this.
