Hello Everybody,
I'm Théo from France. I'm 24 years old, and i begin to shoot with an US Camera. A Speed Graphic Graflex 4x5.
I'm at the step of the processing. But i have a lot of question about the system of the Beseler Base. I explain.
I use "Microphen" developer, on the explanation of this developer, it is written : "For rotary tank with continuous agitation and no presoaking, reduce above development by 15%". I found this sentence a little blurry. Because, all rotary system have not the same speed and other settings can change. I have a rotary base "Color by Beseler" with no reverse system.
I have make a simulation. I have put the two 2509n spire in my 2550 tank + 600ml of water. I have use my chronometer and my Jobo Tank make 40 revolution per minute.
So, i'm a little confusing about 2 things:
First: At which % i must adjust my developing time, with all this information? (I know for exemple that a CPE2, works at 30rpm in "speed 1" and 75rpm in "speed 2")
Second: I have seen a lot of person on many page of this forum who say that they don't change the sense of the Jobo tank during the rotation in unic direction. And a other person change the position of the tank... So: "Who is right?"
Thanks to help me
