    Re: Thick lines and patches on negative

    I have a cheap machine for producing distilled water so it's not a problem for me. I'm getting much cleaner negative when using distilled water in all stages of the process.

    Yes, it is light on the negative, and therefore, dark on the positive image. It's happened on the short side as well, and always with neutral background. Neutral, meaning no texture, such as water or...

    Thanks for the suggestion. Using distilled also improved a lot. With distilled water and energetic agitation, everything seems to be fine so far.

    The two lenses are Schneider and Nikon. The filter holder is a brand new Formatt Hitech.

    On the outside both lenses seem just fine. But I hear a grinding noise when screwing the holder adaptor.
