Collaboration is a tricky thing to pull off. Sometimes the result is atrocious. And other times you get the Declaration of Independence, Rodgers and Hammerstein’s Broadway hits, or the David Bowie-Queen collab “Under Presseure.”

In its collaborative show “Exploring the Roots of Phototraphy,” Gilbert gallery Art Intersections worked with Tilt Gallery and the Herberger School of Design and Art to amass vintage and contemporary works that highlight alternative photo processing techniques. And the result is a show that’s beautiful and educational.

“We have this wonderfully varied exhibition,” says Alan Fitzgerald, Executive Director at Art Intersections. “What we hope will happen out of this is continued collaborative work with other galleries and with other collectors in the valley to continue to build a photographic art community,” he explains.
