"Nature and Travel" at the Caldwell Gallery features photography by Bruce Beron. The show is on view through Aug. 28.

Beron, a resident of Palo Alto, has been photographing his travels for more than 40 years. He is fascinated by abstract design and looks for "the beautiful and unusual in unlikely places." He notes, "Photography has taught me to see the world differently, with more intensity, more purpose in much more detail."

The gallery is on the first floor of 400 County Center, Redwood City.

Concurrently, in the building's downstairs Community Gallery, is an exhibit of photography by Sherrie Shipley of San Mateo, Ellen Lee of Belmont and Beth Mostovoy and Julie Tremelling of Redwood City.

Exhibitions are curated by Teresa Silvestri and sponsored by the San Mateo County Arts Commission. Gallery hours are 8 a.m. to 5 p.m. Mondays through Fridays. Visit www.co.sanmateo.ca.us.

Birthday show

"Food for Thought," an all-gallery birthday exhibition, opens Wednesday at The Main Gallery in Redwood City. A reception will be held from 4 to 6 p.m. Aug. 10. At the reception, 10 percent of sales will benefit the Second Harvest Food Bank.

The show features work by 21 of the center's artists. Their creations center on food evaluation, ranging from a humorous stance to a more cautious warning.

Among the works is a four-panel painted floor screen, "Food Chain," by mixed media artist Katinka Hartmetz, a work which centers on pesticides and genetically modified food.

Another mixed media artist, Ginger Slonaker, focuses on nursery rhymes, beginning with lines from "There was an old lady who swallowed a fly," twisting the tale to absurdity.

The show will be on view through Sept. 8. The Main Gallery is at 1018 Main St., Redwood City. Gallery hours are 10 a.m. to 3 p.m. Wednesdays through Sundays. Call 650-701-1018 or visit www.themaingallery.org.

Found Colors

Coastside artists and long-time friends Marie LaPrade and Barbara Lambert share the spotlight in the show "Found Colors," which opens with a reception from 5 to 7 p.m. Aug. 9 at the Coastal Arts League Museum.

LaPrade creates both objective and abstract digital photographs. She says, "Even as a child I noticed that there are often subtle hints of the extraordinary hidden among ordinary things." This is what she seeks to capture in her images.

Lambert, a retired psychotherapist, creates impressionist and near abstract acrylic paintings. She has taken a number of art classes, beginning with what she recalls was "a transformational art class taught by Margaret Lindsay in 2005." Now she finds herself applying her "strong, intuitional persona" directly to her artistic expression. She begins her paintings outdoors, en plein air, and finishes them in her studio.

"Found Colors" will continue through Sept. 2. The Coastal Arts League Museum is at 300 Main St., Half Moon Bay. Hours are noon to 5 p.m. Fridays through Mondays. Call 650-726-6335 or visit www.coastalartsleague.com.
