“Windows to the Past: Lehigh County” was an exhibition by Matthew Blum that ran from October 24 to November 21, 2019. Blum’s photography brought to life the historic edifices of Lehigh County, places etched in time and registered as national treasures. Utilizing a palette of historical photo printing techniques, from cyanotype to palladium, he captured the essence of structures like the Burnside Plantation and Americus Hotel. The show was not just a visual journey but an educational experience, culminating in a workshop and closing reception that engaged and enlightened the community.
