    Ektachrome at E.I. 20,000 processing

    Here is a process I came across back in the 70's for very dramatic, extremely low light motion photography without flash. You can shoot in almost total darkness with faster shutter speeds. The resulting film is actually a "color" negative without the orange mask. Printing requires .2-.5 additional yellow filtration.

    It is a little time consuming but can be worth the effort. This was intended for Ektachrome 200 daylight film.

    In complete darkness***
    Pre soak for 1 minute at 75°

    Accufine standard solution /// agitate 5 sec every 30 sec
    12 min for EI-1200
    18 min for EI-5000
    25 min for EI-10,000
    40 min for EI-20,000

    stop bath of water or acid stop /// agitate continuously
    30 sec.

    Rapid fix mix as for film w/o part B hardener
    5 minutes /// agitate 15 sec / 1 min.

    Lights can be turned on***
    wash in running water 75°
    15 minutes

    c-41 bleach /// agitate - initial 1 minute
    15 minutes

    wash in running water 75°
    30 minutes

    the film can be dried without wetting agents at this point and final process done later

    final process can be done inder normal room lights - standard c-41 process all steps

    I will upload an image I made using this process when I get a chance.

    The C41 bleach step after the fix will destroy part of the image due to the presence of ammonium ion. You should use a ferricyanide - bromide rehal bleach in this step or it will not yield the optimum image.

    Perhaps someone could explain why this would work. If I had home C41 chems I would try this... I encourage someone to!

    I would be very interested in seeing an example of this.

    Ditto! Even a discussion of what's going on here would be interesting.
