 However, the group's critique of institutional racism in and beyond Britain's art world became a part of the impetus that led to "The Other Story", a seminal survey of African and Asian artists at London's Hayward Gallery in 1989 as well as the founding of the Association of Black Photographers and the establishment of Iniva, the Institute of International Visual Arts – some of which have exhibited Piper's work.His photography was recognised in the 1992 survey by Ten.8 magazine

Piper continued to practise throughout the 1990s, 2000s and 2010s, exhibiting work in prestigious galleries and museums around the world, including, in 1999, the New Museum of Contemporary Art in New York, in 2007, the Victoria and Albert Museum, and, in 2012, "Migrations" at Tate Britain.Examples of Piper's work are held in numerous public collections, including the Arts Council Collection Tate and the Manchester Art Gallery.
