Joni Lui is a photographer based in Toronto who shoots both fine art and commercial photography. She explores intangible concepts that do not appear to have concrete, physical manifestations. These physical manifestation include the concept of time, nostalgia, dreams, and the ability to tell the difference between reality and fiction.

Her first exhibition was in the Toronto Outdoor Exhibition in 2007 amongst hundreds of fellow artists. She has shown her work in Whippersnapper, The Lennox Contemporary Gallery, Paul Petro Special Projects, and many more. She has produced work for Design Exchange, 2nd Half Gallery, and O'Born Contemporary.

Her most notable achievement is winning the Mobile City photo competition in 2008, a joint initiative of the Italian Chamber of Commerce of Toronto, the city of Toronto, and the Province of Milan. She won a trip to Milan for further photography studies, and exhibited in the Museo di Fotografia Contemporanea. She has been published in Mobile City and Sync Resist.
