I really like the effect that’s used in Invisibilia, a series of photographs that have had the subject replaced with an illustration:
Maybe the pictures illustrate the idea that we all want to remove ourselves from life, and replace ourselves with fictional, self-created versions of ourself. We want to fictionalise our own existence, and impose order and narrative where there is none. Or maybe it’s just tracing. Either way, I hope you enjoy the pics.
The fun part is that you can do this with your own photos fairly easily. The artist has provided a tutorial that walks you through the process he uses to trace and replace portions of the original image.
