The Light of Day is a retrospective showcasing the work of Irish photographer Tony O'Shea, spanning 4 decades from 1979 to 2019. This photobook was published to coincide with an exhibition of his work at the Gallery of Photography Ireland, and produced by the gallery and RRB Photobooks.

"The Light of Day is full of natural wonders and human struggles that surface from the borderlands during the Troubles and in the rituals and recreation of his [Tony O'Shea's] city. Each image wants to be a short story."- The Irish Times, 2020
