I've been doing stand dev with Blazinol (Canadian Rodinal) and while I've had good results thus far, I have some questions.. firstly, I've been using 3.5ml per roll of 135, 1:100 dilution, 1 hour duration, agitate at the start for 30sec. NOw, i want to develop some small strips from a pinhole camera I made. about the equivalent of maybe 12 frames of 135. Should I reduce the amount of Blazinol proportionately? So perhaps 1.2 ml or so? Likewise I've been rolling my own film so not every roll is 36 frames.. I've done some test rolls that were 15 frames, 12 frames, etc. Would make sense to me that it would require less developer. Secondly, as i understand it, Stand developing is so forgiving because it basically exhausts all the active developer over the course of the stand time. If so, how critical is the dilution and soup time? I've actually been putting 7ml in 500 so that it fits in the Paterson 4 tank. if you left it for longer than 1 hour, why would it matter if all the developer was exhausted? And, lastly.. I'm trying to wrap my head around this.. Stand dev seems to allow almost everything to be souped in about an hour. Different film stocks, different push/pull amounts, different speeds. (Seems to be a common claim but here is a specific post about it: http://jbhildebrand.com/2011/tutorials/workflow-tutorial-2-stand-development-with-rodinal/ So that would seem to indicate that you could wildly underexpose and/or overexpose on the same roll and the film will magicly know what you want done. The stand process seems to be the same whether you push a film by 4 stops or pull by 2. That seems counter intuitive to me.. Anyway, this has all been amazingly fun thus far. I have been doing standard development with Xtol, D76 and DDX with no problems, I just wanted to wrap my head around what is happening inside the stand dev soup!
