Following in the footsteps of 19th-century botanist Anna Atkins, artist Jesseca Ferguson will demonstrate the cyanotype process using plant materials, on Saturday, January 30 from 10:30 – 1. Ferguson will hand sensitize artists paper and print photograms using ultra-violet light, much as Atkins did when she printed her 1843 book, Photographs of British Algae: Cyanotype Impressions. A buffet-style lunch and a guided tour of the Worcester Art Museum’s Cyanotypes: Photography’s Blue Period will follow the demonstration. To reserve your seat call 1-800-838-3006, or buy online at www.worcesterart.org. WAM members $30, nonmembers $40.
