Re: [pure-silver] Re: Light Leaks with Large FormatI think it was Bob Soloman ( The product line guy here in the US for HP Marketing, the Linhof importer) that said the double taper was used just because it was lighter then the single taper..... Or so I remember...... Anyway, if you get info directly from Camera Bellows, please pass it on.... Frank Filippone red735i@xxxxxxxxxxxxx The current double-tapered bellows are too thick, squeeze together too tight and are consequently overburdened. I think the reason for the double-taper was rigidity, but I think that the new bellows materials used by Camera Bellows are more rigid anyway. Why not use single-tapered bellows, which makes it cheaper, and while at a re-design, drop a few folds, losing a bit of extension but gaining a lot durability?
