I saw some interesting multiple exposure prints last year by Lucien Clergue at the John Stevenson Gallery in NYC (http://www.johnstevenson-gallery.com...e_2002_tn.html). Apparently, Clergue takes daylight rated film, makes exposures indoors, and then lets the film sit for about a year, then goes out and exposures outdoors over the same negatives. The prints are very interesting. ....lyle
