The Portland Museum of Art opens a new show of photographic portraiture Jan. 14. Two newly acquired portfolios by Berenice Abbott and Robert Doisneau, filled with portraits of famous artists and actors of the mid-20th century, prompted this look at the art of photographic portraiture. Drawn from the Museum’s growing collection of celebrity portraits, the exhibition of 35 works will examine the way in which appearance, poses, and props help to define the public perception of an artist’s work, whether it be on the stage or in a museum. The exhibition will also feature portraits of some of Maine’s leading artists including Andrew Wyeth, Stephen Etnier, Louise Nevelson, Robert Indiana, Brett Bigbee, and Dozier Bell, whose work will be on view in the Museum’s third floor galleries. The show runs through April 8. FMI, www.portlandmuseum.org.
