About This Book

A practical manual gives step-by-step instructions for producing vivid colored afterimages: by staring at marked spots on printed plates for about twenty seconds under controlled lighting, then viewing a white surface, observers see transient spectres in complementary hues. It offers guidance on illumination, viewing distance, and size perception, and catalogs plate designs and their opposite-color effects. A second popular-scientific section explains retinal persistence, complementary color phenomena, and basic eye anatomy, classifies visual illusions, and argues that many reported apparitions arise from physiological or environmental causes rather than supernatural agency.
