An exhibition that opens this month at Pamela Youde Nethersole Eastern Hospital's gallery displays the results of an admirable and fun social project. A volunteer group, Art in Hospital, has been visiting hospitals since February this year to host workshops on 'alternative' photography. The project, the Experimental Photo Lab, provides patients with opportunities to express themselves and achieve self-healing. Patients do not need to have formal art training to benefit from the project - anyone can join in. Many of the Art in Hospital volunteers are artists, so they are good at providing inspiration. Workshops were held at Alice Ho Miu Ling Nethersole Hospital and Queen Elizabeth Hospital in February and March. Renowned photographer Tse Ming-chong shared his experiences of making sun prints with the patients. Sun printing is a natural form of photography that doesn't require a camera. All you have to do is collect transparent or translucent objects, such as leaves, flowers, gauze, cotton, feathers or anything else you come across. Place the objects on photo-sensitive paper, then set your design in the sun or in front of a UV light source for a few minutes. Then rinse the paper in water, and the areas of the sheet that were covered by your chosen objects will be in the same colour as the original piece of paper. The parts that were fully exposed to the sun will turn blue. Art in Hospital will continue hosting sun-printing workshops until December this year. Since the charity started in 1994, they have conducted more than 70 art activities. They have painted murals, organised story-telling sessions, published books and promoted the idea of every hospital having its own art gallery. The organisation began with a young artist who was diagnosed with cancer. He was admitted to a hospital ward that had bare white walls. He vowed that once he recovered, he would do something to improve the hospital environment. His health was finally restored, and, when he left hospital, he kept his promise. Experimental Photo Lab - Photo Exhibition Series I runs from May 23 to July 5 and is open from 9am to 6pm daily. The gallery is in the Oncology Department of the East Block at Pamela Youde Nethersole Eastern Hospital. Admission is free.
