Gallery Night & Day runs this weekend, Oct. 17-18, and features scores of galleries featuring fresh work. All galleries have free admission during this event.

Cedar Gallery, 326 N. Water St., unveils a new exhibit called "Visions in Layers" that explores two artists with "an obsessive approach to the process of collage."

The artists, Mary DiBiasio and J. Karl Bogartte, use different printing methods, but both reuse portions of past work to create new pieces, layering images atop images.

DiBiasio, an emerging artist, uses an older intaglio printmaking technique called collagraph and a traditional press to print her works. Bogartte is an established artist who uses a contemporary press and an inkjet printer, which produces digital images via Photoshop.

Milwaukee sculptor Demitra Copoulos curated the show, which opens on Gallery Night, Oct. 17, and runs through Dec. 30, 2008.
