    Tetenal E6 avaialble in USA again

    Tetanal E6 has finally arrived at Freestyle Photo! For those who have not used it, I highly recommend it. Gives results as good as the Kodak chemisry, but easier to use. German engineered.

    Nice, I just got the Fuji 7 bath kit from England and cobbled together the replensher version of the Kodak chemistry thinking that this stuff was getting very rare. Nice to see the Tetenal kit!

    wow! thats scary. can we leave the stabilizer off at the end of processing or use some other form of stabilizer? I understand some other kits like Arista's E-6 kit doesn't even use a stabilizer. Any thoughts?

    Formaldehyde is required for E-6

    Back around the year 2000, the makers of C-41 films changed the formulation so formaldehyde or its precursor, formalin, was no longer required for stability. Sadly, they did not do this for E-6 films. If you have a 6-bath process that includes a pre-bleach step, the formaldehyde/formalin is in the pre-bleach. If you're using a 3-bath kit like the Tetenal kit, it's in the last step.

    If you want your slides to be archivally stable, you must use a formaldehyde or formalin based stabilizer. There's no getting around it. Photo Engineer has written an extensive post about this on APUG, but I forget exactly where it is.

    Shoot more film.
    There are eight ways to put a slide into a projector tray. Seven of them are wrong.

    Sure you can, if you don't want your slides to be stable.

    WTH? If you're scared of working with something because it contains formalin, I'd suggest staying out of the darkroom entirely. It's just not that dangerous.

    WTH indeed! What is it, ya wanna live forever??

    Wear rubber gloves. Provide adequate ventilation. I used to load the tank, and then soup it in the kitchen with the exhaust fan running. Problems solved.

    I would also suspect that the amount of formalin present, and the typical exposure to the user would be of little consequence.

    Exactly. I dissected animals stored in the stuff in high school, and even at home with some Jr. Biology kit or something, when I was a child. Large scale industrial use or people who are exposed all day every day as part of their jobs are a different matter. Soaking your film in a bit of it now and then - that's all it takes. Some reasonable care. If people are really worried about formalin, hope they never find out about the various things under the kitchen sink.

    You may not, but I value my life and take MSDS sheets seriously.

    Did you do a study on this?

    I have made sure I have enough ventilation in my small darkroom. When I do E-6, I keep the door open. But I still want to treat carcinogenic chemicals with respect. There is a reason why E-6 processing has been relegated to the crazy few.

    The stabilizer is a required step, see B&W film doesn't need it, because silver is a natural bactericide, in colour films the silver is fixed out, and bacteria love gelatin, so it needs to be poisoned in some way so that the bacteria don't eat it. C41 films now use a different chemical for this, E6 uses formaldehyde for this.
