A hidden gem in Uptown, hidden inside Spirit Square. The Light Factory is a small, but incredibly fantastic museum and cultural hub for photography and film in Charlotte. They hold regular rotating exhibits, summer camps, and adult art classes. I usually browse the current show when I'm in the area or waiting on a performance at McGlohan or The Duke.
Another very fun thing you can catch is the summer film series, outdoor (weather permitting) screenings of films in Transamerica Square (the green between the buildings). This summer saw 80s cult films...all for free!
Cool spot, interesting exhibits, and definitely friendly on the wallet when you need something to do Uptown.
