Black, White, and a Little Local Color
Somerville Toy Camera Festival is a two-month festival that showcases photography created with "toy" cameras, which are essentially rudimentary, low-tech cameras. The opening exhibit of the festival, called "Black, White, and a Little Local Color," opens Saturday at The Washington Street Art Center. About 13 photographers are featured in the exhibit, and the opening reception is from 7 p.m. to 9 p.m. at the art center, 321 Washington St. Other exhibits in the festival will take place at the Nave Gallery and the Nave Gallery Annex.

Tax Free Weekend
As a reminder, you don't have to pay sales tax on Saturday and Sunday on most things that cost less than $2,500. So, go out there and buy something you'll regret!
