Not a book of optical illusions, but a complete treatise on the optical principles used in magic. The book covers Retention of Vision; Position Illusions; Blackout; Angles of Vision; Background masking and blending; Mirrors; Lighting; Lens transmission; Chromatics and much more. If this sounds like one of your high school physics books, fear not. The reading is incredibly interesting and really exciting! The author gives many examples of tricks and illusions using the principles he explains. You will be fascinated (so thats how those are done!). Not just for the stage magic guys. Close-up folks will find lots and lots of valuable information within. This book will become a classic of magic. It belongs on every magicians shelf. [Editor's summary]
