Leica is selling a swank advert brochure for $10 -- you can gt an abbreviated PDF on their website.
If you're just wanting to see the photos, which are buy Ralph Gibsin, get a copy of the recent Leica Fotographie Int'l (or was it Leica World?) that also contains them.
(BTW, teh new LFI also has an article on B&W scanning)
If you are a fan of Ralph Gibson, check out a brand new interview with him posted on www.JPIMAG.com. It's a new online photo magazine we are starting. It is not officially being announced yet but the beginnings are up. I am hoping it will be a follow up to Camera & Darkroom that no one can take away from me.
I just found a pretty cool book -- published by Gibson's Lustrum Press in 1978 -- that details some of his late-70's darkroom practices. And a lot of other folks' too. Title "Darkroom" edited by Eleanor Lewis. A second "Darkroom 2" was edited by Kelly Jain but *sigh* my library doesn't have it.
I'm fascinated at his mention in his Bergamn GRaphics interview about scanning WET prints -- I've been reluctant to try but might just go for it (like a wet-gate cine transfer? hmm). The Leica stuff has the most attenuated gray tones I've seen from him yet.
