    Rodinal works very well with our current fiber papers.

    Adjust the dilution to get a fully developed image in about 5 minutes.
    Omit the bromide unless you absolutely need it.
    1+25 is a good place to begin.

    You get a different curve than typical developers, and a long scale. Try it out with a 'fat negative', generous exposure and gentle development.

    Sounds good - I'll try it out on some Varigam (oops ADOX FINEPRINT) next time I'm in the darkroom with a well fed negative

    Tom, what are gaslight papers? Matt

    Gaslight papers were fast emulsion papers (usually silver bromide) that could be exposed by gaslight (as opposed to exposure by sunlight). Recall that gaslights were common late in the 19th century and early in the 20th century. Silver chloride contact paper emulsions (Azo, etc.) are slow and require a lot of UV light for exposure.

    If the Rodinal is of the traditional type made with p-aminophenil.HCl, it should have enough potassium chloride in it to serve as antifog for chloride paper. Is AZO the only chloride paper now?

    I've used Rodinal 1+10 for silver bromide paper (ok Ilford multigrade) cause I had no real print dev left, it worked ok no trace of damage to prints stain or anything bad.

    Terrible waste of Rodinal... now I read this recipe oops.

    Rodinal was sold for use with plate and paper, later films for many years, as were Ilford Certinal (released around 1908), Johnsons Azol, Kodak Ltd's Kodinol and a few other Rodinal clones.

    Agfa actually recommend various dilutions for paper ranging from 1 to 20 to 1 to 100 the addition of bromide really depended on the papers being used. It was also recommended for Lantern slides. Original Rodinal was slightly less concentrated than modern R09, 80% of the modern strength.

    HiIan

    Thanks I used Azol for a long time cause I had an Agfa daylight tank and Afga published times for continuous agitation in Rodinal.

    Even way back I was aware they were generic formula.

    You must be at least 103 to remember Azol, Noel :D


    Joking apart it had gone by the time I began serious photography.

    HiIan

    You were correct they offered 1+16 dilution for contacts can't have read the instructions.

    My bottle was the 100cc glass rubber stopper under plastic screw cap, about '62... must have been cheaper than 4s. Still had some Azol left until 79 when I needed to switch to Rodinal.

    I had a periflex gold star in 62 to replace earlier 127 Brownie.

    Seems like yesterday.
