Collections, like people, have personalities. The personalities of good or very good collections are recognizable while remaining at least a little bit unpredictable. That description certainly applies to the collections on display in “An Enduring Vision: Photographs From the Lane Collection,” which runs at the Museum of Fine Arts through March 30, and “Building a Collection: Photography at the Fitchburg Art Museum,” which runs through Sept. 1.
William Lane, one of the MFA collection’s two namesakes, began collecting American Modernist painters and works on paper in the 1950s. He met his future wife, Saundra, in 1962. They began to collect American Modernist photographs, starting with the estate of Charles Sheeler, in 1965.
