    Rodinal Special: It's Not Rodinal But Is It Special?

    Hi All,

    I am wondering if anyone had any experience or opinions on Rodinal Special (a.k.a. Studional)? I've seen a supply of it and I'm wondering if it's worth picking up a bottle or two. Seems interesting enough, although I understand it has very little in common with standard Rodinal.

    I don't think it's offering anything over & above most one-shot fine grain developers, but it's convenient. I used to use it a lot when it was previously in the UK (early '80's!), but used it at 1+30 rather than the recommended 1+15, increasing the times by about 50%. The neck of the bottle is the right size to use a 20ml syringe, which will just about reach the bottom of the bottle.

    It's sound like it's the equivalent to D-76 (1+1) or XTOL (1+1) in terms of grain and actuance. Would that be correct?

    I've used it and I like it. It's the best developer for Ilford HP5+ that I've found. Now that it's available again, I'm going to buy some. I have the formula -- or what purports to be the formula -- that I found several years ago on a german website, but I'll pass on mixing my own and just use the pre-packaged. FYI, it's not like Rodinal - much finer grain, different look. Try it, I think you'll like it.

    I use it. I like it as a dev*. It's not one-shot, I get under 20 rolls out of half a bottle of conc mixed up to a litre.

    * though I don't like mixing it up - experienced significant vision distortion shortly afterwards.

    I use it to process Agfa Scala as a negative film, and am very happy with its performance.

    I use both Rodinal and Rodinal Special. The name Rodinal Special is a bit misleading as it has little to do with Rodinal as far as I know. Rodinal Special provides finer grain than Rodinal but the short dev times at 1:15 probably does not appeal to a lot of people.

    Unfortunately there is little info on the web for higher dilutions but I worked out my times for use with Acros at 1:30 and like it.

    Agfa Rodinal Special (a.k.a. Agfa Studional) is a P/Q (Phenidone/Hydroquinone) developer. Looking at the Agfa MSDS, I noticed that Triethanolamine (aka 2,2',2" nitrilotriethanol - and aka TEA) is the alkali ingredient. So, sure, buy some if the price is right. Should give results similar to DDX, Microphen and TMax.

    I use it quite a lot with HP5+. I like the results.
