“Struktura Ciemności” is an independent, short student film (an “etiuda filmowa”) directed by Maciej Herzog. It is a project associated with the prestigious National Film School in Łódź (Państwowa Wyższa Szkoła Filmowa, Telewizyjna i Teatralna im. Leona Schillera w Łodzi), a renowned institution in Polish cinema.
I have not seen the film. These captures come from the Nudografia page, which also includes images from her previous nude scene.
According to Google she has another nude scene which is not on Nudografia
