The 5 diptychs of Metro Bastille show the artificial underground features of subway producing mental gaps in our relations with others. D0 shows 5 views of the subway station “Bastille” in Paris photographed during the Covid pandemic. To the empty corridors, distorted shapes and silhouettes of subway passengers photographed before the pandemic have been added. They are parts of masses moving from one point to the other, in an environment close to space alienation. As such, their inability to interact with others erases the boundaries pre and post-Covid, with empty corridors and distorted silhouettes merging into one balanced scene. At D+, the light exposure and appropriate chemical treatment make the silhouettes more visible, though their visibility in time remains questionable due to the lack of fixing solution. At current light exposure, the combined effect between contrasted forms and faded environment exacerbates the ambiguity of human behavior in adverse environments.
