Behind White Shadows of Image Processing

In Behind White Shadows, the "Angel of History" sends its friends and colleagues an email with the photos of two female figures attached. These two images, modelled after real women, are still seen by many people. However their name and identity remain unknown. The Angel writes: "While contemplating these images, I had to think about other women, whose faces were put through similar histories. Forever resonating within the realms of image processing - wether they chose this fate themselves or not. As it seems your face is amongst them, I wondered if you could share some of your insights." The Angel receives replies subsequently from the leader ladies, Lena, Ariane and a render ghost.
