The image depicts an indoor classroom or lecture hall environment in Sofia, Bulgaria. Four individuals are visible from behind, seated at wooden desks, facing a front wall. In the left foreground, a male student with short dark hair wears a dark top. Behind him and to his right are three female students; one has dark curly hair, and another with long brown hair wears glasses. A white Epson projector is mounted on the light-colored ceiling, projecting an image onto a white pull-down screen. The projection displays a hand drawing a circle divided into eight segments, illustrating a mathematical or conceptual division, with partially visible Bulgarian text including "Като например заплатите" (As for example salaries). To the right of the projector screen, a white marker board is visible. Fluorescent light fixtures are integrated into the ceiling. Windows along the left wall are covered by white horizontal blinds, allowing diffused light into the room. The walls are a two-tone combination of a lighter yellow/beige on the upper section and a white lower section, separated by a white border. A light blue vertical element is visible near the window frame. On the wooden desks, various objects are present, including a black Dell laptop, a brown cardboard box, and a red cup. In the immediate foreground, a black backpack belonging to the photographer is visible, decorated with multiple colorful pins, including yellow, pink, blue, white, and a heart shape.
