Her partner of many years, the cultural journalist and publicist Günter Engelhard, editor of her books and author of many texts about her, created poetic picture titles for her photographs.

Angelika Platen has photographed a considerable amount of contemporary artists, including in Phase I, Georg Baselitz, Joseph Beuys, Christo, Hanne Darboven, Walter de Maria, Dan Graham, Blinky Palermo, Sigmar Polke, Gerhard Richter, James Rosenquist, Günther Uecker and Andy Warhol.

In Phase II, she photographed Marina Abramović, John Armleder, Christian Boltanski, Jeff Koons, Neo Rauch, Julian Rosefeldt and Thomas Struth, among others.

On the occasion of the 1998 exhibition Angelika Platen - Photo Works, the Museum für Moderne Kunst in Frankfurt am Main acquired a collection of the photographs taken between 1968 and 1974.

Her collection begins "on the threshold of the turn of the 20th century" with photographs by Berenice Abbot (Eugène Atget), Man Ray (Pablo Picasso)[1] all the way to Robert Mapplethorpe's and Duane Michal's portraits of Andy Warhol.

[3][4] Angelika Platen is "an outstanding artist portraitist", wrote Andreas Kilb in the FAZ in 2018: Hanne Darboven's 2002 photograph is "one of the masterpieces of the genre because it turns the celebrity into a human view".
