Ho's distinctive approach to photography broke with traditional techniques, and framed the uniqueness of Hong Kong. His images, while strictly adhering to the aesthetic sense and pictorial styles of modern photography, are truly sensitive to the realities of ordinary people, such as drivers, construction workers and women wearing cheongsam, all of which can be categorized as works of art.

A fan of black-and-white photography himself, Ho once said in an interview with Hong Kong media organization, M+, "it's not that I don't take color photographs, but I have realized one thing, colors don't fit well in my world".
