While digging through the archives of her 50-year photographic career, Wales-born Marian Delyth felt as though she were unearthing “fragments of a lifetime of chasing the light”—a reference to William Henry Fox Talbot’s notion of “painting with light.” The “fragments” in this solo exhibition at Ffotogallery are particularly focused on moments of public activism in Wales. Delyth was on hand for the anti-apartheid rallies in the 1980s and photographed the Welsh singer ​​Dafydd Iwan as he performed for a crowd in Cardiff. More recently, Delyth documented the Aberystwyth Clean Water protest in 2024, which saw swimmers and surfers out in the water with cardboard signs. —Paulina Prosnitz
