Hello All,Can the "constant agitation" be the keywords? I can imagine that a periodic "some" inversions in 30sec-1min-2min-etc. is far enough from constant agitation, so Rodinal die later. A friend of mine made an experiment with a third of a roll of T-Max in Rodinal 1+250 (2ml Rodinal in 500ml water), 90min at 24 °C (75 deg F.) Agitation was once in every min for the first ten minutes, then 30sec in every 5 mins. The result was OK, so it seems to me that if the agitation is not continuous, Rodinal doesn't die so soon.
The real question is: is there a difference between eg. 20min of thin rodinal and 40min? Should the rodinal die after 17min there should be no difference... after all, sloshing the film around for a few more minutes in dead rodinal won't change anything.
Personally, I don't care... I spent a few weekends with games like this and found no visible differences in the results, so I use faster development.
