I have several questions regarding the use of Rodinal to develop sheet film when using either a Jobo rotary processor or BTZS tubes. I shoot 4x5 black and white landscapes; I typically enlarge to 16x20 or 24x30.
First, because these methods use constant agitation, what dilution is best to use? If, as I assume, a higher dilution of Rodinal is preferable, do I have to worry about the developer exhausting since the Jobo drums and BTZS tube in particular have limited capacities?
I have heard that the addition of sodium sulfite to Rodinal helps to soften the grain, which might be desirable for 24x30 prints. I would prefer not to make any noticeable sacrifices in sharpness however. Any advice?
I currently plan to use Ilford FP4+ or possibly FP5+. I have used these films in 35mm in the past and enjoyed them. Until recently I have been using Fortepan 200 film in 4x5 with D-76 1:1.
Thanks in advance
