This week

• Beginning Friday, the Addison Woolley Gallery presents ”Ghana: An African Portrait Revisited,” an exhibition of photography from the sub-Saharan country. The show opens with a reception from 5 to 8 p.m. Friday as part of the Portland First Friday Art Walk. The exhibition will remain on view through March 26.

The gallery is in the Bakery Building, 61 Pleasant St., Portland.

In 2006, six photographers from New Hampshire — Peter Randall, Nancy Grace Horton, Barbara Bickford, Gary Samson, Charter Weeks and Tim Gaudreau — journeyed to Ghana to document the country on the eve of its 50th independence anniversary.

They were following in the footsteps of American photographer Paul Strand, who traveled the country during the early days of its independence. Strand published a book, ”Ghana: An African Portrait.” The six New Hampshire photographers published their work in 2007 in a book that shares the same title as the exhibition.

In conjunction with the Addison Woolley show, the Museum of African Culture, 13 Brown St., will show Ghanian art and artifacts. For information, visit www.addisonwoolley.com.

• The Portland Museum of Art hosts the annual Youth Art Month Exhibition through April 4, organized in conjunction with the Maine Art Education Association. The show displays more than 100 works of art by students from around the state, in recognition of the role of art education in Maine schools.

The exhibition is open now, and will be celebrated with an opening reception at 5 p.m. Saturday at the museum.
