    Does anyone have density data for this combination (sheet film)? I can't find it in Kodak's data sheets. Paul Butzi has some partial data for TMX rated at EI 64, but I remember that John Sexton rates TMX at EI 80 in TMax developer. Since XTOL increases shadow density, I'd like to see whether this combination yields a true 100 speed film (FB+F). I plan to do my own film testing, but I'd like to minimize the required number of exposure/development iterations.

    I have a BTZS test I did on TMax 100 with XTOL 1+1 in a Jobo. A speed of 80 is what I got with this film for a normal exposure. I can send you the file if you use Plotter.

    Thanks Larry. I don't use plotter (I do my analyses in Matlab), but I would greatly appreciate either raw exposure/density data or a plot of the curve. Did you find the Kodak recommended time (9min at 70 degrees F) to be about right for normal exposure, or did you have to reduce development?

    Here is a PDF export from Plotter. I think it should have everything you need. Note that my temperature is 24C/75F vs Kodak's temp of 70F. My dev time for N will be 4.5 minutes.

    Thanks

    Thanks Larry. This was exactly what I needed.
