I just acquired a "Color by Beseler" processing tube for 16x20. I intend to use this for processing B&W paper by rolling it by hand. (I don't have enough space for 5 16x20 trays) I was hoping instructions on how to load this thing will be rather obvious but it's not. Can someone familiar with this help? Seems there's almost no information on the "net" on how to use the tube itself.
When I take one side of the cap off, it's just a cap. When I take the other side off, it has a long inner attached to it that goes the length of the tube. This inner tube sits non-concentric to the outer tube. On inside, there are ridges along the length of the tube. What is this inner tube for??
How does the paper go into this and secured? I don't see any obvious slots, clamps, etc to secure the paper in any way. Does it just get rolled length wise, emulsion side facing in and gets inserted along the perimeter? How does it even stay without collapsing when chemistry goes in and get rolled?
Sorry, it's so basic but I can't seem to figure this out....
