    This is for Rodinal? I understand today's commercial Rodinal may be different from the original formula, but I may give it a try.

    I guess that means 3 drops of KBr per ounce of mixed solution - not per ounce of Rodinal?

    Good question! Fond as I am of experimenting, I see no reason to do this? The other way around - yes...

    Next time I fell really adventurous I'll try Dr. Vogel's Acidic Iron Blue Developer. That's exitement and uncertainty enough for me .

    It's done for the same reason that some people like to go scuba diving with helium in their tanks instead of oxygen. It just gives them a different diving experience.

    Man, you are sooo set in your ways.

    The reason people use helium is so they can do deep dives to 250 feet plus and not experience the toxic effects of O2 at that depth. Also at shallower depths say around 180 feet helium is great because you do not experience the narcotic effect O2 gives you at that depth. Something that is kind of important if you are working at depths.

    It's part of using the right tool for the job. All I am wondering is when using film developer for paper is using the "right" tool.

    Hey I'm a crankie old bastard and proud of it, damit! Just ask Aggie.

    Hah!! My chance to jump on someone for an obvious error.

    O2 is narcotic at .... ? Maybe so, but I don't think it would be a good idea to replace ALL of it with helium. Replacing the avaliable nitrogen (N) with helium (He) - and leaving the oxygen alone might work well.

    Where are the smilies ... got 'em ... :P

    My main reason for doing this is to see what happens. I have no practical reason for wanting to do this, but then I have no practical reason for doing anything in photography since it is not my profession. But then again, I've never been accused of being practical

    Eric:

    I was just trying lamely to make a joke. I honestly didn't know that people used helium for diving. I thought it was only used for filling balloons and talking like chipmunks. I thought if you used helium to dive you would die and float quickly to the top. (not good).


    But you are still sooo set in your ways.
