Ghosts and Spectres

Here is another interactive display, in 1864 J.H.Brown published a book called Spectropia, we have taken 4 of his prints to display here; By staring at one of the images for roughly 25″ without blinking and then looking away at the white screen on the wall the visitors will see the image of the spectres appear before them floating on the wall, this is due to an illusion called afterimage, a phenomenon where the image continues to appear in one’s vision after the exposure to the original image has ceased.
