I've been thinking long and hard about the 1:100 Salt process. I like the intense contrast but as we know there's the lighter streak on the right.
My theory is that despite the salt being dissolved, over the 1 hour period there has been some form of seperation of the salt and water on a microscopic level, the salt thus settling to the bottom of the tank.
This may be confirmed by the 1:25 Salt not displaying the streak, due to the much shorter dev' time and the frequent agitation and therefore re-mixing of the Salt/Water/Rodinal solution?
I'm assuming the right hand side of the film was on the bottom, thus receiving the higher salt concentration, therefore producing a darker side to the neg' and as a result, a lighter positive image.
So I'm going to run the test again of the 1:100 Salt. This time dev' will still be 1 hour but with a 10 second agitation every 10 minutes.
Note: Yes there are other methods, developers or films to achieve the same or better result, but I like the look of the neg'. So what's the harm? It's my time, life, money etc . . .
Besides, I really fancy the idea of having a development technique named after me (or my 'net alias).
P.S. Maybe gravity has been the secret achilles heel of Stand Developing all this time. Seperation of Water and Developer with accumulation at the bottom of the tank equals uneven development ??
