A thought photograph by Ted Serios (ca. 1967), taken from the book: ‘Photographs of the Unknown’. Serios claimed the ability to project mental images onto photographic film, sometimes with the lens cap still on and sometimes with no lens at all on the camera. Once, trying to ‘picture’ the Hilton Hotel at Denver, Colorado, he obtained this image of the Chicago Hilton instead. Pseudo-scientific studies on his work contain highly intriguing footage. This kind of psychic imagery recalls notions of ‘seeing without a seer’.
