Afterimage or Ghost image

  • One of the most common afterimages is the bright glow that seems to float before one's eyes after looking into a light source for a few seconds
  • If the viewer stares at this image for 20-60 seconds and stares at a white object a negative afterimage will appear (in this case being cyan on magenta). This can also be achieved by the viewer closing his/her eyes and tilting their head up.
