Hello,
I'm new to developing 4x5 negs. As the title states, I'm looking for a cheap motorized base solution for my jobo expert 3010 tank. I noticed the two most commonly mentioned bases are the one by beseler and the one by unicolor.
Can anyone tell me their experiences with either (mention specific models please). I am interested to know if there would be a variation in development times, etc with a non jobo base (when compared to a jobo processor).
I think I read somewhere that Jobo recommends a 50rpm speed and reverse after 2 rotations, some of the beselers are around 15rpm I believe. Another thing I read was that a 5 minute presoak (using a jobo machine) will give similar development times to tray development charts. Would this still apply as a starting point? (I plan on testing, but want a basis to start on for dev times)
I know that there are some beseler motors that feature reverse and it seems like most people disable the reverse and manually turn the tank every minute or so because the diameter is too large on the jobo for a complete rotation. Is this correct?
Thanks in advance, Dan
