This book showcases an exciting new collection of images from two of the world's leading creators of stereograms. Both based in the United States, Levine and Priester have been at the forefront of the development of this exciting art form. Stereograms are 3-D images hidden within other pictures. They have a long history and their ability to trick our perception has been a source of fascination for centuries. These visual conundrums possess the ability to infuriate and delight us in equal measure. This brand new collection presents a twist on the usual approach, with each illusion deriving from a realistic photographic scene.
