Your new exhibition showcases 50 photographs of temples, churches and burial grounds across Southeast Asia. Why are you interested in sacred places? Mary Padua, HKU Department of Architecture assistant professor: 'Consumerism and materialism dominate the everyday aspects of contemporary society in many parts of Asia, especially in urban China. 'Meanwhile, religious places continue to serve as focal points for local culture, and some have evolved into tourist destinations. I wonder what these places represent physically. But I mainly want to celebrate the mundane aspects of sacred places as a visual aesthetic. I'm most interested in contemporary society and various aspects of how people live now in our hyper-manic technologically driven world. And whether I can slow the tempo through my work. You use traditional black and white, as well as digital darkroom techniques. Why? Digital darkroom work allows me to experiment in colour, especially for print-making. I custom-printed most of the colour works in the exhibition. I think it's important to continue with tradition, and black and white photography will continue as a fine-art medium - unless they outlaw the chemicals for environmental reasons.'
