Pushing E6 film times, starting points

Discussion in 'Film and Processing' started by steve g, Jan 31, 2005.

  1. Greetings<br>
    I am processing E6 film using the Kodak 5L 6bath E6 kit. After two
    runs I have the system down with my Jobo, and I am looking to push. I
    understand that for pushing, you incrase the first developer time. I
    have pushed B&W film before, frequently. Probably 1/2 the rolls I
    shoot get pushed.<br><br>So my question is, what is a good starting
    point for pushing E6 film in the Jobo with the Kodak 6bath kit.
    Should I go by the same general B&W push rules? (1 stop ~1.4-1.5x, 2
    stop ~1.85x-2.25x although for B&W.. it varies a lot by
    film)<br><br>In case it varies by film, I would be doing Fuji Astia,
    Fuji Sensia 100, Fuji Provia 100, Fuji Provia 400, Kodak EC400 and
    Kodak EPL 400X.<br><br>I am mostly just looking for a starting point
    here so I don't have to blow film on just getting to a starting point.
    Once I have a starting point I can tune it for my taste/films, but I
    would rather not just toss it in an extra 50% and see what happens
    without some guidance.
     
  2. Pushing E-6 films requires additional time in the first developer only.

    A 1-stop push = 2 minutes extra time in the first developer, +1/2-stop + an additional 1 mintute...+2-stop + an additional 4 minutes...and so on...
     
  3. Sounds good, I knew that only the 1st dev time increased, but had no idea of what factor that was. I will have to play around with that this weekend.
     
  4. Stephen;

    Remember that a push in E6 equates with a drop in Dmax in the film. Blacks will go gray.

  5. Stephen,

    Depending on the model of Jobo, with the EK 5 liter kit you can also raise the temperature of the first dev bath 8 degrees F for one stop, 12F for two stop and 16F for 3 stop pushes. Corresponding drops are -6F for one stop and -13F for two stop pulls.

    Corresponding times *with this kit are +2, +5, and +10 minutes @100F for 1, 2, and 3 stop pushes; and -2 & -3 minutes for 1 & 2 stop pulls.
