"Render ghosts": James Bridle thinks we have another way of haunting digital media. These are people's images that we recycle through multiple uses far removed from their origins. For example, Lena Söderberg becomes Lenna, widely used test image. Stock photos are another instance of render ghosting.
They inhabit a space which exists only in the virtual spaces of 3D computer rendering software, projected onto billboards, left to rot and torn down when the actual future arrives; never quite as glossy or as perfect as our renderings of it would like it to be, or have prepared us for.
The Render Ghosts are waiting for their own end.
The recycled uncanny, perhaps.
