I' m thinking about buying a 2521 JOBO Tank and a 4x5 reel in order to process m y 4x5 sheet films by inversion. I know that' s not very economical, from the poi nt of view of chemicals (1500 ml -inversion- vs 270 ml -rotating process with a Jobo Expert system - for 6 sheets) but, on the other hand, I don't have to deal with the price of Jobo Expert Drum. Is somebody on this forum using this process (inversion) and how are the result s ? How to calculate the times of development with such a process ?
Thanks for any reply
