Stoškus works with medium- and large-format cameras to create detailed black-and-white photographs of the unspoiled parts of the old town of central Vilnius. Cars, advertising, signs of tourism, and even the presence of pedestrians — all are minimized in order not to detract from the architecture, his main interest.
Following Barocke Sakralarchitektur in Wilna (also published in Polish), for which he contributed the photographs, the first book dedicated to Stoškus's work was Vilnius: Photographs of the Old Town, a collection of some thirty images with an introduction by Raminta Jurėnaitė, who describes Stoškus both within a strong tradition of photography of Vilnius and as akin to Eugène Atget and Bernd and Hilla Becher as a systematic creator of documentary architectural work who is yet not commissioned.
