Summertime, the next art exhibit at the Jamaica Plain Branch Library, not only has a timely name, but it also features the work of 19 youth photographers. Ranging in age from 11 to 15 years old, the students are training at the Big Picture Art House, which trains middle schoolers while traveling around Boston. Classes are structured around themes like Storytelling or Street Photography, while others focus on making movies or documentaries. The works on view in Summertime include a mix of subjects and styles -- color, black and white, still life, portrait -- while capturing locations like Old Orchard Beach, the Franklin Park Zoo, the Lynch Family Skate Park in Cambridge, and Narragansett, RI. The students in the show are from Brookline, Jamaica Plain, Roslindale, Newton, and other Boston-area towns.
