Every picture tells a story or so the cliche goes. If that’s true, then a photographic exhibit opening tonight at the Birmingham Civil Rights Institute offers a look into the lives of 40 families with a Birmingham connection. 40 lesbian families. “Living in Limbo: Lesbian Families in the Deep South” is the creation of award-winning photographer Carolyn Sherer, who herself has been in a committed relationship with another woman for more than 30 years. Sherer tells Greg Bass she was inspired to create the exhibit by the death of a friend and it’s unpleasant aftermath.
