For 50 years, historian Richard Shaw has been collecting and photographing people, places and things in the Bangor area. Some ended up in the eight books he has compiled for Arcadia Publishing. Others have been packed away, waiting for this chance to share them with an audience. Photographs show the Great 1911 Bangor Fire, the 1937 Brady Gang shooting, and 1960s Urban Renewal demolition. Lesser known images picture weddings, river scenes, and life inside the Bangor Daily News, where Shaw worked as an editor and writer for three decades. Early techniques will be explored, when photographers lugging heavy equipment risked life and limb to capture natural disasters on wet plates. Daguerreotypes and three-dimensional stereoscopic images will be shown, along with vintage postcards. The digital revolution will also be probed. A related video will be screened in the seminar’s second hour. Richard Shaw is a Bangor native who writes the monthly Bangor Metro magazine photo feature, “Then & Now.” He is always photographing people and places arond Maine, and every weekend explores antique shops and thrift stores looking for rare tintypes and postcard views. Two of his more unusual finds include a photograph of his mother at an Eastport shop and one of his father in Portland.
