I use two baths when I am too lazy to use strictly controlled bw developing (like ZS). Thornton's version of Stoeckler formula and Tetenal's Emofin are two which I use most. 'common internet knowledge' says that 2-bath developers are easy, doesn't care about temperature, time or agitation. Ofcourse many of us know that some, like D-23 cares. At least some degree. Emofin also seems to care, as the datasheet suggests fast agitation especially for push developments. Knowing that, I happened to leaf through the book 'The Ansel Adams Guide, Basic Technologies Of Photography, Book 2' by John P. Schaeffer. At page 91 the writer states that result of divided developer was indentical when film was developed using Jobo at 68°F and 80°F. The used developer is not mentioned clearly. It was possible D-23, but could be Farber AB too. That's a bit confusing. Emofin's develop times varies by temperature (according to datasheet). I have impression that results of D-23 derivatives varies as time or temperature changes. The agitation method also affects the result of D-23 derivatives, I presume? How is that actually?
