“Two by Two: Two Couples, Four Photographers” is on view through Jan. 6 at Maine Farmland Trust Gallery, 97 Main St. The public is invited to hear a talk by the artists — Ralph Hassenpflug, Kathryn Oliver, Drew Sanborn and Margaret Lindsey Sanborn — Friday, Nov. 18, at 4:30 p.m., followed by a 5:30 to 8 p.m. opening reception

When it comes to photography, these couples are two peas in a (tri-)pod. For both pairs, being photographers together is a core part of their relationship — not unlike farming is to many farming couples. At Maine Farmland Trust Gallery, each of these four photographers is showing a selection of his or her work.

Oliver has been an artist her whole adult life. She met Hassenpflug when he contacted her to collaborate on a photo series in May 2013. It was a dance series, and she participated as the subject. Shortly thereafter, they became good friends and eventually fell in love.

“Ralph inspired me to step behind the lens myself,” said Oliver. “So we continue to bounce ideas off each other, share critiques but we pursue our own projects independently.”

Hassenpflug was born in West Germany and studied European literature in Germany and France. He immigrated to the United States in 2002. He is a self-taught photographer who regularly presents his work in national and international shows. Both often work in black and white and their images are rather dream-like, said curator Anna Witholt Abaldo, “but that is where the resemblance stops.”

The Sanborns typically photograph and exhibit together. They often spend several hours working at the same location — it could be an old farm, an abandoned mill site or perhaps an historical building, said Margaret, who was not a photographer when the couple met.

“I would come along when he was taking pictures,” says Margaret, and Drew proceeded to give her a camera. “I had liked photography in my childhood — but I was always interested in abstract stuff, and was told I was taking the wrong kind of pictures!”

A common thread in their work is their interest in the still-visible remainders of Maine’s 19th- and early 20th-century history. Abandoned machinery from farms and factories, evolving rural landscapes and even libraries of vintage books are all viewed with a contemporary sensibility.

“Margaret and Drew know how to do justice to the beauty and personality of all things old,” said Witholt Abaldo.

MFT Gallery is open weekdays from 9 a.m. to 4 p.m. For more information, visit mainefarmlandtrust.org. Maine Farmland Trust, a statewide, member-powered nonprofit working to protect farmland, support farmers and advance farming, created its gallery to celebrate agriculture through art and to inspire and inform the public about farming in Maine.
