    parodinal as a print developer

    Has anyone else tried this?

    I tried it yesterday. I used the parodinal version that doesn't use potassium bromide. It gave out nicely toned prints on generic paper. I used 1:20 dilution and my usual water bath.

    I haven't tried it yet, but I mean to. What you describe sounds quite similar to this recipe found in the chemistry recipe section on APUG: http://www.apug.org/forums/article.php?a=220

    I"ve thought about this. I did develop Azo a few times in Rodinal 1:20.

    I really liked the final prints i got from this brew...I'm seriously thinking of using this as my primary print developer rather than D76. The prints I made had a warm brownish tone, I cant wait to try this with split - grade printing.

    You use D76 for paper?

    paRodinal should work with paper. I used old sheets of bromide paper to test paRodinal (if it indeed was able to develop) when I was first brewing it. The paper blackened- solid black- almost as soon as it hit the concentrated solution.

    Since paRodinal is just like real rodinal, the comments from the ORWO FORMULAE book could apply- and here is a quote:

    [SIZE=2][FONT=Times New Roman]"R 09 can be used even for developing photographic paper. In doing so, suitable papers show a warm tone.

    Ratio of diluting : Contrast

    1+5 to 1+10 : Normal
    1+20 : Soft
    1+30 to 1+40: Extra Soft (especially for two-bath developing)

    Attention! durability and utilization of highly diluted R 09 developer are less than those of special paper developers."
    [/FONT][/SIZE]

    Some papers, notably those marked 'rapid' RC types have hydroquinone or some other developing agent incorporated in their emulsions. As such they often need only a strong alkaline bath to start developing. These paper often show a rather warm tone when subjected to such alkaline activator baths.

    Since I'm thinking of picking up a bunch of Rodinal here shortly just in case (yeah, I know it's around, but I don't want it getting hard to find on me) I thought about experimenting with something like this after I had some experience with printing. I've heard of the really nice results, but I haven't really seen them. Anyone have some print scans that would give me an idea of how they look?
    No idea what's going to happen next, but I'm hoping it involves being wrist deep in chemicals come the weekend.

    Yeah, I second that, let's see prints if someone has something they want to show.

    EDIT: If that doesn't happen, I'll have to get around to do some myself and post. But that'll take a few days or a week...

    Another consideration. p-aminophenol, the agent of either Rodinal or Parodinal, is synergistic with either hydroquinone or sodium ascorbate. 4 grams (1 teaspoon) of ascorbate in a liter of 1+50 Rodinal is about as active as 1+25 Rodinal. If you use hydroquinone, control the color of the print by adding more or less sulfite.

    Actually the next stage would be adding hydroquinone. The soup i used didn't use potassium bromide, I'm thniking of using by newest batch whech has about a gram of potassium bromide for every 250 ml. how would this affect the print?
