This indoor shot taken in Leudelange, Luxembourg, shows a classroom or conference room setup. In the background, a projector screen displays a diagram with the text "Même charge prise différemment," followed by "Dans le sens de la longueur" and "Dans le sens de la largueur." Below the screen, a power strip is mounted vertically on the wall, featuring both USB ports and electrical outlets. A sheet of white paper with a green pen on top dominates the foreground. In the lower left corner, a stand with documents can be seen. The room is illuminated by recessed ceiling lights.
