Confused amateur photographer on cross-processing E6 with C-41

Discussion in 'Film and Processing' started by penny_greenberg, Jan 23, 2008.

  1. I recently got my slide film (I use Kodak Elite Chrome 100) cross-processed
    because my high school teacher a year ago told me to try it out. When I got it
    done at a photo lab, I was confused by the result. I expected the film to be
    positive since when I got my slide film developed, it was always positive, but
    the slides looked negative. Is this supposed to be the result of cross-processing?

    Another question is, what do I do with the cross-processed slide film? The only
    thing I ever did with slide film is use a Daylab, make polaroids, and then did
    emulsion or dry transfers but Daylabs don't invert the colour, so what should I
    do with this negative coloured slide film?

    Thanks for taking your time to read this. Sorry if I sound bewildered or
    unintelligent since I'm really an amateur.
  2. It sounds as if your situation is normal as that is what is expected of using a slide film and processing it as a neg in c-41. If this isn't to your liking you will have to print it like a neg to get a more positive image. Since your end process is with the daylab you might try using negative film and having it cross processed in e-6. This will give you more of a positive image to start with. You should bracket images with a test roll to find a good ISO to start with.
  3. There's no fundamental difference between E6 and C41 film. Either film will yield a negative image when processed in C41 chemistry, and a positive when processed in E6. Color negative film has that pesky orange mask though, so "slides" produced with such film would not look very good, unless there's a very specific effect you're after.
  4. Have your cross processed negatives scanned to a CD or scan them yourself the us an imaging program on a computer to make prints or have prints made at your local pro lab.
  5. Lesson learned, I guess, because I'm confused, why a teacher would suggest this. Why cross-
    process E-6 film to negatives? Ok, for an exercise, but why didn't the teacher have examples
    to show what happens instead of suggesting it? Why ruin good slide film? Ok, I'm a longtime
    slide shooter, but still...
  6. Scott, didn't your teacher tell you you'd have a roll of "art" instead of plain ol' snapshots? ;)

    Best thing to do is scan them and then play with the results in Photoshop.
  7. Tak Imura: Is it possible to use color film (normal C-41 film) with a Daylab? Because I would like to try cross-processing C-41 with E6.
    Fredrik Sandstrom: The only effect I was going for was the slightly green tint that E6 cross-processed pictures look like. So does that mean that when I cross-process C-41 with E6 chemicals, then the film will be a positive instead of a negative?
    Larry Dressler: I'm really into using the Daylab so I'm not all that big on scanning in images. Thanks for the suggestion.
    Scott M. Knowles: The reason she suggested it was because I was doing independent study and she suggested trying cross-processing slide film since I've used slide film before. The thing is, I never tried the cross-processing while I was in her class so she never gave me any more information on it.
    Jeff Kelley: Yeah, I scanned the film and just inverted the colours and it came out somewhat like what I expected to see. Here is a scan of my film (the colours aren't exact and are lighter in real life):
    After I inverted the colours in Photoshop:
  8. When cross processing slide films in C-41 process you will have an increase of contrast and boost of ISO, looking at your strip of negatives I can see that the exposure of neg #8 & #9 was severely over-exposed, #6 & #7 look fair but the lightning in the scene was comming to much from the top, not enough from the front, the eyes are in the dark, but still just work a bit more with photoshop. Cross processing does not give great results without some work and testings. regards,
  9. And a bit more not art but you get the Idea. when I Xpro slide filme I rate it 1-2 stops faster one of my favorites is Elitechrome 200 at 400. Larry
  10. daniel fortier: Just to make sure, slide film cross-processed will come out as a negative like the first strip of film I posted?
  11. yes, in C-41 process all you get is negative.

    When cross processing became popular it was before scanning & photoshop, we had to use an enlarger & print the "funny" negatives it was slow & long to achieve a great print.

    Regarding the way you like to use polaroid print, the only option to get a positive slide that could work would be to shoot Kodak gold 100 GA-135-24 exposed it at 40 ISO and have it process in E-6 normal.

    When cross processing negative films in E-6 slide process there is a loss of speed.

    The 40 ISo is a starting point, also if shooting people try a few frames with a blue filter 80B or 80C it will reduce some of the overall yellow cast that this type of cross process give.

    You could also add filtration in the dialab while making your prints.

    Post some results. regards
  12. SK: Yes you can use C-41 developed in E-6 with your Daylab but as someone already mentioned you would have an orange base to print through. This in itself may be kinda cool but if you wanted to color balance the print you might want to test any filtration (cc gels) to put in front of slide (neg).
    I don't remember the Daylab having much power so you may have to settle if the filtration gets too heavy (too much density). good luck
