Born in Los Angeles, California, on July 10, 1969, she is the daughter of Bridget (née Mori) and the actor David Hedison.

[3] As a photographer,[1] in 2005, she exhibited the (Re)Building series, which addressed themes of loss, transition and recovery while using construction as a metaphor for memory in the architecture of the subconscious.

Her series of large format photographs entitled Ithaka, which takes its title from the CP Cavafy poem of the same name, was shot in the temperate rain forest of North America.

[citation needed] Hedison's work is represented in public and private collections worldwide, and her photographs have been shown in solo and group exhibitions in galleries and museums throughout the US and Europe, including Los Angeles, New York, and London.

[13] Hedison has also appeared in multiple television series including Showtime's The L Word as con artist Dylan Moreland.
