Ms. Fineman wanted to examine the speechlike nature of cellphone photo-chat through a finer lens: artists’ longstanding habit of communing with others of their kind. So last fall she selected a dozen artists of varying ages, origins and sensibilities, working in photography, painting, illustration or multimedia. Each was asked to invite another artist to communicate through a shared iCloud album for several months, however often they liked but without typed messages. (Ms. Fineman could check in, taking the project’s pulse, but not comment.) The museum would exhibit each exchange unabridged; images would be labeled with only the sender’s name and the date sent.

Ms. Fineman had little sense of how her recipe might work, but in April she lifted the lid to find the makings of this marvelous exhibition nearly done: some 1,822 images, including 183 videos. Two conversations are displayed as photographic prints on the gallery’s walls; four are slide (and video) shows on digital monitors. Six are on iPads or printed in books stationed at tables with seating. An inviting, plain-spoken ambience prevails — part gallery, part archive.
