In 1975, she received her BA from Queen's University where she studied Studio Art. In the 1980’s, high in the mountains of California, a fascination with the beauty of her surroundings inspired her to render her interpretations through photography. She studied a Freeman Patterson photography course at Loon Lake, New Brunswick, and colour photography with Ed Burtynsky in Toronto.

After a few years of experimentation and self-teaching, and inspired by Picasso Still Life drawings and the softness of Renoir paintings, Diana developed her own unique technique of hand colouring fibre base black and white silver gelatin prints. She has received grants from Ontario Arts Council and Hamilton Arts Council and awards from the Canadian Association of Photographers and Illustrators in Communications (CAPIC) and Applied Arts Magazine.
