    Ok, I looked at a few of these on line.

    What I have been considering prior to this is an RO unit.

    I'm going to start a new thread asking for comments on the difference.

    I guess it is determined upon how important the photo is. Would I do it? If the subject was important, yep. One of the things taught at NESOP was recovery from issues.

    Anything can happen in chemistry. I don't happen to believe your hypothesis is correct. Water is more like it.

    Have a great life.

    I stated clearly at the start of the thread that I process multiple rolls per week using this water and have never had a problem.
    Anyone wants to call Adox or Agfa and suggest them to produce Rodinal with tap water - why waste money for distilling water?

    Do the spots appear on the leader and tail?

    Or only within the image frame?

    Good questions.

    Sensor needs cleaning?

    Only in the image. Unexposed areas are clear.

    Had a PM from someone who knows what they are talking about who agrees it is nothing to do with the water. Suggests the Rodinal (Adonal) is to blame.

    Your camera chamber is contaminated with clouds of developer dust? Hmm.

    ... OR ... Check very carefully any areas of the film outside of the images that are a little gray or a lot gray but not black. For example if the leader black shades to gray over the space of a few millimeters, check there very carefully to see if there are spots. And check any pressure streaks or crimp fog or light fog and check at the edges of the numbers and edge markings.

    If the dots are not in any unexposed areas, then it is very localized over development of silver.

    Are there clouds of developer dust in the darkroom air? Unlikely.

    Check the developer to see if it is perfectly clear or if there is sediment that gets stirred up or specks that are suspended almost colloidally. Also, check the developer after it is fully diluted, too.

    This is typical in Pinhole photography

    My first post, way back at the start should have been
    "This look like light scatter in Pinhole photography, was this a pinhole?"

    I thought it, and should have added it to my questions of processing. When I was doing a lot of pinhole I saw them all the time. Even in when not pointed at a strong light source.

    One thing maybe to prove this to you is that you can find the same pattern on different frames. Now one roll may not be enough to see, But on the hundreds of pinhole frames I have done I could see similar patters of black spots.
    D-76 is a standard developer, although not one I use.

    If you suspect the Rodinal, mix 100ml at 1+25 with your tap water, then strain through a coffee filter and check it for sediment. If you have to, you can let it dry and scan the filter to check it.
