For my own mural darkroom in the future, I'm sure I will come up with something slick for washing, I always do well at figuring it all out. For now, the rental darkroom has what it takes to deal with these monsters.
I love problems because I love solving them.
Drew, where the heck does one locate a 105mm Rodagon G? Is it just the non-Apo version of the lens and is it F/4, 5.6....?
