[1] Jarcovjáková photographed nightlife, minority groups and marginalised people in the 1970s and 1980s in Prague and West Berlin, and made self portraits.

[2] She made diaristic work of her hedonistic lifestyle, and of the inhabitants of a clandestine gay bar that she visited almost nightly, in 1980s Prague, where the Communist state was institutionally homophobic.

Jarcovjáková's written diaries and photographs from Prague, West Berlin and Tokyo between 1971 and 1987, were published in the 2016 book Černé Roky (The Black Years).

[5][6] Between 1983 and 1985, Jarcovjáková photographed the inhabitants of a clandestine gay bar in Prague, called T-Club, which she frequented visited almost every night,[3][7] using black and white film and a flash.

Sean O'Hagan, writing in The Guardian, described the work as having an "edgy diaristic approach, laying bare a life lived recklessly amid a period of political repression" [. . .]
