“Just Another Diamond Day” is a show of works by Stephen Bron at Albert Merola Gallery, 424 Commercial St. in Provincetown, opening Friday, July 30 and running through Aug. 18. Bron’s intimate oil paintings are snapshots of small, tender moments — a leaf in the snow, the peeling bark of a birch tree, a bird’s nest on the ground — that feel like a visual diary. They leave one wondering how he does it — before settling into the seduction of his surfaces, and the manipulation of juicy paint that’s alive with possibility. The gallery is open Wednesday through Sunday, 11 a.m. to 5 p.m. There will be a reception on Friday, July 30 from 6 to 8 p.m.
