Not many people know what a photogram is. To help adventurous people create these unusual and fascinating art forms, the Hong Kong Museum of Art is organising a photogram workshop next month. It will be conducted by award-winning photographer Machteld Stikvoort-Zaaruolo from September 24 to November 5 in the museum's printmaking studio. A photogram is produced by using a photographic method that involves transformation of objects by light and chemistry. She will use slides and her own works to explain and teach the techniques involved. Participants will experiment with different objects such as feathers, teddy bears and flowers, together with light and light-sensitive papers, to make their own photograms. The course, backed by the Urban Council will be taught in English on seven successive Tuesdays, with each session being held from 6.30 pm to 9 pm. The course fee is $350 plus about $200 for extra material. Application forms are available at the museum building in Tsim Sha Tsui. The deadline for applications is September 12 and places will be allocated on a first-come first-served basis. For more information call 2734 2155.
