Photojournalist Kristen Ashburn has trained her lens on devastation of the political kind (Iraq) and devastation of the natural kind (Hurricane Katrina). In BLOODLINE: AIDS AND FAMILY at the Atlanta Photography Group Gallery, the New York-based photographer turns to devastation of the human kind. Beginning in 2001, Ashburn traveled to sub-Saharan Africa and spent months documenting the impact of the disease on the family and social landscape. The results are 31 black-and-white lightbox images of the young and the old, the healthy and the sick, caught in unguarded everyday moments. Ashburn speaks about her work Sat., JAN. 31. Artist talk: Free. 10:30 a.m. Exhibit: Through March 6. Free. Wed.-Sat., noon-4 p.m., or by appointment. Tula Art Center, 75 Bennett St., Space B-1. 404-605-0605. www.atlantaphotographygroup.org.
