Actually, far from introducing shibboleths, the statement was included
to point out that Zia is not _quite_ the Holy Grail and that for some
goals other processes are better: no invidious comparison at all. I also
admit that I didn't know gum or bromoil prints can equal the definition
of Pt/Pd or Zia: I've never seen one that does but am willing to stand
corrected. Generalizations are doomed to misunderstandings, but magazine
writers are forced to include some generalizations unless the editors
let us have an entire issue for a single story.
BTW, Judy, I'll be in town, almost your neighborhood I believe, next
Tuesday. If you'd be willing to take a little time to show me some of
your work in gum, I'd be delighted to stop by and increase my knowledge
of the topic.---Carl
