Digital BW, The Print

Clayton,
I ran the gist of the early part of this thread by some Adobe
engineers and beta testers. Aside from the standard "no benefit"
response (of which I was guilty as well), those who had actually tried
it concurred with your results, that in some cases bumping from 8 to
16bits before large edits yielded a benefit. The explanations were
more anecdotal, than an official Adobe position on the matter, but
thanks for putting this information out there. If I get any definitive
technical explanations from Adobe I'll pass them on.
