MANY OF THE photographs in "In This Instant" have appealing-sounding titles referencing food, home, and family. And a few of the images actually deliver on their monikers, like Kirsten Nordine's Sprite and Cookies, an affectionate look at the colorful clutter of her teenage sister's bulletin board. But this wholesome and clean-looking slice of life is the exception among Nordine's photos, the rest of which closely examine household dirt: a pillowcase yellowed with years of use, for instance, or the remnants of a home haircut on a linoleum floor. Maybe a family member wouldn't think twice about this stuff, but an outsider (or someone who feels like an outsider) would, and Nordine comes off like an alienated teenager bent on portraying her family in the worst possible light. David Black and Kathryn Miller also focus on bits and pieces of the everyday – Black through informal portraits of his family members, and Miller through her unconventional views of a house (looking out from under the bed or examining pale spots on a wall where picture frames once hung). Rebecca Veit's Prim and Pink series comes at the end of the show, and after so many close-ups of facial pores and carpets and smelly-looking pillowcases, it's easy to read her photos in a somewhat similar way, although it's unclear whether her title is intended to be ironic. Veit focuses on a woman's body – her face as she eats a spoonful of grapefruit, her knees balancing a teacup, her hands folding a blanket. The woman is obviously coiffed and pretty, but it's impossible to miss the tiny flaws that the rest of the show has conditioned us to look for. Arm hair, leg hair, and little cuts and moles all loom large in a way that is simultaneously fascinating and icky. Wed.-Fri., 1-5 p.m., 521 Seventh St., S.F. (415) 864-2222. (Lindsey Westbrook)
