As hinted at by its title, Cynthia Daignault's show "Which is the Sun and Which is the Shadow?" takes light as the overarching subject of its big and small oil paintings. In the gallery's front room, busily brushed, large beige canvases dominate; in one corner, a window in one painting seems to cast light onto a neighboring canvas. Her 2012 show here sported a grid of small canvases of CCTV monitors; this time around, she skips the mediating device. The back room plays host to a grid of 365 small paintings, each showing the sky, whether cloudy or crystalline blue.
