I never use a center column. It compromises the whole triangulation stability effect of the legs themselves. Might be OK for a light field 4x5 at modest extensions,
but not for anything more serious. And I never bought into that "if it's was good enough for EW nonsense". It was good enough for him to not even know how to
drive; it was good enough for him to soak his fingers directly in pyro and mess up his health; and if most of his negatives were significantly enlarged, they'd look awful. But I do commend anything Ries.
