    Shanghai 8x10 100 Film Test

    I got some Shanghai 8x10 100 film to try. I ran a strip of it against HP5 that I usually use.

    Both strips processed at the same time.

    Results show it to be three stops slower than the HP5. Those "ISO" numbers are compared to some Tri-x previously tested and defined in the software as "ISO 400"

    Sounds about right, I have been shooting it in 4x5 for a few years (probably 1000 sheets at this point) and I settled on 50 iso working well for me.

    Good to hear, seems most film works best at 1/2 rated ASA

    took me some time to accept that all film is rated by all manufacturers incorrectly one stop fast

    I made a lot of thin negs

    I shot my 14x17 at ISO 80 and developed in Pyrocat HD 2:2:100 and the negs came out great for carbon. Good stuff.

    Realize in my test I'm comparing it to HP5 and Tri-x which I defined as "400." This is not any in-camera test, so if one's "in-camera" test requires those films to be rated at 200, then this Shanghai would likely need to be 25.

    I recently got a new meter (Sekonic 588), so I have yet to re do my in-camera test with the new meter. Right now I just pointed the new meter and old meter at a number of targets and adjusted the calibration of the 588 so they read the same. I have yet to confirm with in-camera test at this time.

    That in-camera test needs to be done with daylight and it is dark when I go to work and dark when I come home. (shortest day was just yesterday).

    I just read Fred Picker's take on film speed and compensation, from his old newsletters.

    Very interesting

    I still do my in-camera test like in the book. I expose a uniform target at various meter EI settings and use the one that resulted in 0.1 density on the film. With LF it is important to focus at infinity, not on the target (unless you WANT the bellows factor for that actual target distance always incorporated in your EI)

    That’s the Shanghai on the left? I have found to build contrast quickly. I rate it at 50 and develop it in Pyrocat HD, 1:1:50. Seems to tame it fairly well. I’m always happy when someone else’s tests confirm my own experiences.

    Three questions on the film.
    Glitches and problems with the emulsion finally gone away?
    How does it compare to Ilforf FP4+ in tonal separation, especially in mid tones?
    How does it react with plus and minus development compared to our old standbys, FP4+ and Tri-X?
