The I Spy book series has captured the imagination of millions of readers. Part of what made these books so magical is that all of the images were created with real objects. Photographer and photo-illustrator Walter Wick carefully arranged each scene and hid the objects. Then author Jean Marzollo wrote the rhymes. Since I Spy Walter has written and photographed the Can You See What I See series and Hey Seymour!. Walter's newest book A Ray of Light uses beautiful photographs to teach kids about the principals of light.
