A search for "Rodinal" brings up quite a list of different developers on Freestyle.
For those using Rodinal of some sort, I'm interested to hear which formulation you are using, and if applicable, the differences between them that you have found. Also, why did you choose that formula?
There are numerous and conflicting reports about Rodinal and its many iterations. I don't really care about what Rodinal was in 1920 or 1946 or whatever, and I know that many of our older users here might actually bring that up, but what matters to the modern film shooter, is what you can buy today, off the shelf. I wonder if these different formulations might actually be better, or worse, for certain applications, or are they all basically the same?
A project for another day will be to buy one of each and do a comprehensive test, but that'll have to wait as I have no patience for that right now.
What spurred this question was a fresh bottle of Adonal I just opened. It seems to be different than the last bottle of Adonal I had. Usually when I dilute the developer with water it turns a light orange color. This time it stayed perfectly clear. My negatives seemed a bit "flatter" than normal. Wondering if they had changed the formula, I did some Google searching and the best I could come up with is some claims that Rodinal (Adonal) can get "seasoned" over time from exposure to air. I'm wondering if it was due to being freshly opened - my old bottle of Adonal was at least 6 months old. I have made some great negatives with TMX and other modern emulsions in Adonal but if the developer seasons or changes after exposure to air I'm less inclined to trust it for repeatable results.
