  1. Re: Adox CMS 20 Slides, what bleaching chem ???

    This is very interesting, especially the high temperature processing. Which dilution did you use?

    Re: Overhead still lifes

    Drew, I'm interested in this attachment for a different use - in-camera paper positives. Does the attachment reduce overall image quality?

  7. Re: Adox CMS 20 Slides, what bleaching chem ???

    I'm not Malanov but this is the process which gave me very decent results for Adox CMS 20ii in 135 format, in case you're interested in knowing:

    PEG isn't a magic bullet IMO. Increasing the proportion of an ingredient beyond what is recommended can potentially cause unintended effects. You can try adding hypo, but it may reduce density in...

    Re: B&W Paper Reversal New Method?

    Interesting approach! Did you notice any loss density when using periodate+chloride bleach on paper? As paper has chloride in it, wouldn't Ammonia eat up some of it and lead to loss of density?
  14. Re: Adox CMS 20 Slides, what bleaching chem ???

    Could be due to underexposure. What is your exposure index for this film? It won't give the box speed of 20 in anything other than Adotec developer. I rated the film at 6 and got pretty decent slides.

    Re: agfa neutol wa formula

    Ok, I get it now. This formulation is roughly the same as Kalogen. If its activity is also similar, then you can perhaps start with 1:50 dilution for developing film. Good luck.

    Any darkroom timer app on your smartphone that beaps once every minute should be good. Just make sure you hide the phone in a thick jacket or something that cuts off the light from the phone.
