The three photos on display showed a farm in West Virginia, sand dunes and an interpreter at Colonial Williamsburg, Va.
Gamble said his grandfather had been a photographer, and when he was helping clean out his grandmother's house, he wanted to find the cameras.
"I was always interested in the big lenses," he said.
After locating the cameras, he "played around with them," and started taking photos, he said.
The Greencastle-Antrim High School ninth-grader said he is considering a career in photography.
The Rev. Doug Hodges of Greencastle said he spent about a year creating the sculpture "The Girl From Trang Bang." He also wrote an accompanying poem which tells the story of the 9-year-old Vietnamese girl, Kim Phuc, who was photographed running along a road near Saigon while on fire from napalm.
She survived and now lives in Toronto.
A slightly different version of Hodges' sculpture received an Honorable Mention at the Mechanicsburg Arts Center.
Videographer Andrew Wertner, 18, received a scholarship from the Arts Council, given annually to graduating seniors pursuing a career in the arts.
Wertner's video, "Behind the Camera," was a humorous depiction of the making of a longer video, "Rubber Gangsters III."
The son of Jim and Kathy Wertner, Andrew will attend DeSales University in Allentown, Pa., this fall to major in film and television.
Across the street at the Greencastle Presbyterian Church, the Wentz family of Greencastle played folk and Celtic music.
Yvonne Wentz said she and her husband, Mike, have been playing music together for 18 years. She taught their three sons, Joel, 16, Justin, 14, and J.P., 9.
They perform together about once a month, she said.
Shawn Craver, 32, has been singing and playing clawhammer-style guitar since he was 16. An employee of Citicorp, Craver performs around the Tri-State region about twice a month.
Craver's son Luke, 9, joins him on the banjo occasionally.
