In Camera Lucida, Roland Barthes makes an ontological elaboration on the representation of those who had already been taken down by photographic or video devices and proposes the concept of Ça a été (that-has-been): the images testify the once presence of themselves and connect the past to the future. Eventually, they will reach a whole new existence free from any pre-determined subjects and contexts. Also, the concept itself expands in the rapid communication of information age; on one hand, the technology allows people to connect with people and creates multiple representations which verify the connection between self and others; on the other hand, it also gradually demolishes the remain of the human warmth. By employing the unique recording quality of photoluminescent pigments, these works confirm the waning of the aura and human connections that was once here but now gone by; however, it is also only through this impermanency that we learn to cherish those who and which remain.
