JOBO Expert Tanks for 4x5 film processing

[Robert Ruderman]

Hi,

Has anyone any experience with using a JOBO Expert Tank for MANUAL 4x5 processin g? How difficult is it to use (loading film, loading and draining chemistry, et c.)? I am trying to weigh the difference between the expert tank and the 2500 s eries tank.

Thanks, Robert

The common wisdom on Usenet seems to be that the expert drums are marvellous devices giving extremely even development. On the other hand I have f riend who uses the 2500 tank for B&W and he sees no reason to bother with the expert drum.
