Matthias Geiger has created a world where people leave behind outlines of themselves wherever they go. His series of images is titled Tide.
The aim of Geiger's work is to demonstrate how people have all been in the same place, just at different times. By looking through them one can see the non-human side of things (such as landscapes and architecture). Geiger's silhouettes also blend together, sending the message that humans are not part of an individualist society but rather part of a whole.
The pictures from Matthias Geiger give off a ghostly aura as if the figures are just passing through and that time and space are irrelevant. Perhaps one leaves traces of themselves and just never looks back to notice.
