Ghosts everywhere - Halloween must be just around the corner. This is a fascinating piece I saw over at Photojojo.com. William Hundley’s “Entoptic Phenomena” photography series is a collection of ghosts images - but not really. The piece has a link to Mr. Hundley's entire series and also gives away the "trade secret" technique used in producing the images. It's a fun read - check out the entire "otherworldly" article right here.
