Peter Ashworth is an English photographer. Ashworth initially specialized in music photography, between 1979 and 2000. In the 1980s, he worked with many UK artists including The Smiths, Depeche Mode, Eurythmics, Soft Cell, Jimmy Page and The Associates.
He has also performed as a musician with various bands, including Marc and the Mambas (with Marc Almond), The Gadgets, and The The. In 1980, Ashworth—using his Triash pseudonym—was briefly a member of the band The The with Matt Johnson. In 1982–1983, he played drums as a member of Marc and the Mambas.
He now works predominantly in fashion and style/culture photography, working with fashion designers such as Stephen Jones, Basso & Brooke and Atsuko Kudo. He is known in part for his photography of fetish subjects, for creating sets and shooting on location using lighting techniques that explore the textures and cut of his subjects.
Ashworth's work is featured in The National Portrait Gallery permanent collection archive, consisting of twelve images: Adam and the Ants - Kings Of The Wild Frontier; Annie Lennox - Eurythmics: Touch & Face to Face portrait; Frankie Goes To Hollywood - Welcome To The Pleasuredome; Soft Cell - Bedsitter & Non-Stop Erotic Cabaret; Associates - Sulk; Erasure - phone-booth; David Sylvian - portrait; Julian Cope - Saint Julian (album); Visage - debut sleeve; Steve Strange - portrait.
