Hello, I've recently aquired a Jobo multitank 5 (2551) with two reels for 4X5. M y question is, how much developer do I use in this system? As I understand it, y ou don't fill the tank completely, and the tank rests on its side submerging any one portion of the film at a time. There is a second part to my question. Someo ne told me, I could use this tank just fine by floating it in water and rotating it myself; however, I don't know how many revolutions per min. I assume you rot ate it in one direction for a few rotations, and then you roll it backwards for one. I do not know this for a fact though, which is why I'm asking you. Also, in this type of developing process, does one have to use more time or less time, a s it is constant agitation. I would apprecitate any detailed information into th is process. Thank you.
