text: I ordered this book primarily for the benefit of my 7 year old son. We're doing a research project on oceans, and while we have a few good resources, I felt this one, with its 3d imagery, would more likely capture and hold his attention. What I didn't realize was how thoroughly it would capture and hold mine. For me, 3D had always meant multicolored plastic glasses and headaches. Though the book was described as stereoscopic, I didn't understand what that meant. Stereography was something new for me, even if as a form of photography it is over 150 years old. 
  
  This is not a matter of red and blue separations; the 3D results from the human eye's trick of blending 2 photos taken (simultaneously) an eye's width apart.  Photographer Mark Blum is a pioneer in the art of underwater 3d photography, and his work is beautifully displayed here.  Everyone I've shown this book to has been fascinated by it, and I fully expect that when we've finished with our project the book will find its way to permanent display in my home
