    35mm 140lp/mm film

    I'm always finding amazing little things on Erwin Puts web site. This is one of those.

    "My first results with the new Spur DSX32-64 developer and Copex microfilm are very promising. The useable sensitivity of the film is EI 50, where you get excellent densities over a range of ten stops. The curve looks quite normal and brings a good CI value. This is a much improved result compared with previous attempts to introduce the Gevaert Copex film into pictorial photography. I would prefer ISO32 as exposure index, but that is a matter of taste.
    Resolution is outstandingly good with 140 lp/mm, twice what you get with the M8 and the current crop of digital top SLR cameras."

    I await to see his results.

    I'm presuming you are working with a negative film. Which of the three Copex neg films are you using? Any info an how well it does or doesn't take a pyro stain?
